82 Animals That Start with E: From Eagles to Eyelash Vipers
October 23, 2026
Few letters of the alphabet produce a stranger mix of wildlife than E. Within a single list you get continent-spanning raptors, a lizard so secretive that herpetologists call it the “Holy Grail of reptiles,” a wolf with fewer than 500 individuals left on Earth, and a fish capable of delivering a jolt strong enough to stun a horse.
This collection of animals that start with E spans mammals, birds, reptiles, amphibians, insects, and more than a dozen dog and livestock breeds that trace their names to English counties, Siberian forests, and Swiss mountain valleys. Whether a reader is hunting for animals beginning with E for a classroom project or simply curious how many distinct creatures claim this letter, the 82 entries below cover the full range, including several endangered animals starting with E that conservationists are racing to protect.
1. Eagle
Eagle is a catch-all name for roughly 60 species of large birds of prey found on every continent except Antarctica. The golden eagle (Aquila chrysaetos) is one of the most widespread, hunting rabbits and ground squirrels across mountains and open country in the Northern Hemisphere. Eagles rely on exceptional eyesight, estimated to be several times sharper than human vision, to spot prey from great heights. Many species mate for life and reuse the same massive nest, or eyrie, for decades, adding fresh branches each breeding season.
Birdwatchers often confuse eagles with smaller raptors like kestrels and kites, which share similar hunting techniques but occupy a very different size class covered in our bird names that start with K guide.
2. Eagle Ray
Eagle rays glide through tropical and subtropical waters using wing-like pectoral fins that can span several feet across. The spotted eagle ray (Aetobatus narinari) is easy to recognize by the white polka dots scattered across its dark back, a pattern that helps it blend into sunlit, sandy seafloors. Unlike stingrays, eagle rays spend most of their time swimming in open water rather than resting on the bottom, and they feed by crushing mollusks and crustaceans with flattened teeth plates. Despite a venomous tail spine, they pose little threat to swimmers unless provoked.
3. Eared Grebe
The eared grebe (Podiceps nigricollis) is a small diving waterbird best known for one of the most dramatic body transformations in the bird world. Before migration, it can double its body weight by gorging on brine shrimp, becoming so heavy that it temporarily loses the ability to fly. Large staging flocks gather at saline lakes such as Mono Lake in California and the Great Salt Lake, where hundreds of thousands can congregate at once before completing their nighttime migratory flights.
4. Earless Monitor Lizard
The earless monitor lizard (Lanthanotus borneensis) is a semiaquatic reptile found only on the island of Borneo, and it is the sole living member of its entire family, Lanthanotidae. The earless monitor lizard is a semiaquatic, brown lizard native to the Southeast Asian island of Borneo, and it is the only living species in the family Lanthanotidae. Despite the name, these lizards are capable of hearing, although they lack a tympanum, an ear opening, and other externally visible signs of ears. They grow up to 1.6 feet (50 centimeters) long, with slender bodies, tiny limbs, and tails they can grasp things with.
Important Note: The earless monitor lizard is protected under CITES Appendix II and is illegal to collect or trade in most of its range. Its secretive, burrowing lifestyle makes wild sightings exceptionally rare, which is part of why herpetologists prize any confirmed encounter.
5. Earthworm
The common earthworm (Lumbricus terrestris) spends most of its life tunneling through soil, swallowing dirt and organic matter as it goes. This burrowing behavior aerates soil and recycles nutrients, making earthworms one of the most important invertebrates for healthy gardens and farmland. Earthworms breathe through their skin rather than lungs, which is why they need consistently moist conditions to survive and often surface after heavy rain.
6. Earwig
The European earwig (Forficula auricularia) carries a pair of pincer-like appendages called cerci at the rear of its body, used mainly for defense and to grip prey such as aphids. Despite an old folk myth suggesting earwigs crawl into human ears to lay eggs, they are harmless to people and rarely bite unless handled roughly. Earwigs are mostly nocturnal, hiding in dark, damp crevices during the day and emerging at night to feed on decaying plant matter and small insects.
7. East Siberian Laika
The East Siberian Laika is a hardy spitz-type dog (Canis lupus familiaris) developed by indigenous hunters in the forests of eastern Siberia to track elk, bear, and sable. Built for extreme cold, the breed carries a dense double coat and the compact, muscular frame typical of working northern dogs. Independent and high-energy, East Siberian Laikas are better suited to active owners with space to roam than to apartment living.
8. Eastern Barred Bandicoot
The eastern barred bandicoot (Perameles gunnii) is a small, nocturnal marsupial once common across the grasslands of southeastern Australia before introduced foxes and cats drove it to the brink of extinction on the mainland. Conservation breeding programs and predator-free fenced reserves have since helped reestablish wild populations in Victoria and on islands off Tasmania. The species uses its long, pointed snout to dig for insects, worms, and roots at night, retreating to a nest of grass during the day.
9. Eastern Bluebird
The eastern bluebird (Sialia sialis) brings a flash of sky-blue plumage to meadows, orchards, and golf courses across eastern North America. Males display a brighter blue back with a rust-colored breast, used to attract mates and defend nesting cavities from competitors. Because natural tree cavities have become scarce, backyard nest boxes have played a major role in helping bluebird populations recover after a mid-20th-century decline tied to habitat loss and competition from introduced starlings.
10. Eastern Box Turtle
The eastern box turtle (Terrapene carolina) is named for its hinged lower shell, which closes almost completely to protect the head, legs, and tail from predators. These slow-moving reptiles can live for 50 years or longer in the wild and tend to stay within a small home range of just a few acres for their entire lives. Eastern box turtles are omnivorous, eating everything from mushrooms and berries to slugs and earthworms as they shuffle through forest leaf litter.
11. Eastern Brown Snake
The eastern brown snake (Pseudonaja textilis) is one of the most venomous land snakes in the world and a significant cause of snakebite incidents across eastern and central Australia. Despite its dangerous venom, the species is actually shy and will typically flee rather than confront a threat, only striking when cornered or startled. Eastern brown snakes are agile hunters, pursuing mice, lizards, and other small vertebrates through grasslands and farmland.
12. Eastern Chipmunk
The eastern chipmunk (Tamias striatus) is instantly recognizable by the dark stripes running down its reddish-brown back and the way its cheeks bulge when stuffed with seeds and nuts. Rather than fully hibernating through winter, eastern chipmunks enter a lighter torpor, periodically waking to snack on food stashed in underground burrow chambers. A single burrow system can stretch more than 10 feet and include separate chambers for sleeping, storage, and waste.
13. Eastern Coral Snake
The eastern coral snake (Micrurus fulvius) displays a warning pattern of red, yellow, and black bands that inspired the familiar rhyme “red touch yellow, kill a fellow.” This secretive species spends much of its life underground or hidden beneath leaf litter in the southeastern United States, rarely encountering humans despite carrying potent neurotoxic venom. Several harmless snake species have evolved similar banding as a defense strategy, making accurate identification important before assuming any banded snake is safe to handle.
14. Eastern Cottontail
The eastern cottontail (Sylvilagus floridanus) is the most widespread rabbit species in North America, thriving in everything from suburban backyards to farmland edges and open woodlands. Females can produce several litters a year, a reproductive strategy that helps offset heavy predation from hawks, foxes, and snakes. Cottontails rely on freezing in place and sudden bursts of zigzagging speed, rather than burrowing, to escape danger.
15. Eastern Diamondback Rattlesnake
The eastern diamondback rattlesnake (Crotalus adamanteus) is the largest rattlesnake species in the world, with some individuals exceeding seven feet in length. Its diamond-patterned back provides excellent camouflage in the pine forests and coastal scrub of the southeastern United States, where it ambushes rabbits and rodents from coiled positions. Like other pit vipers featured in our animals that start with V list, it uses heat-sensing pits near its nostrils to detect warm-blooded prey in total darkness.
Pro Tip: Most rattlesnake bites happen when people try to handle or kill the snake rather than simply giving it space. If a rattlesnake is encountered on a trail, the safest response is to back away slowly and let it move on undisturbed.
16. Eastern Dobsonfly
The eastern dobsonfly (Corydalus cornutus) spends up to three years as an aquatic larva, known as a hellgrammite, hunting other insects along the bottoms of clean, fast-flowing streams. Adult males develop enormous curved mandibles that look menacing but are too weak to deliver a meaningful bite, used instead for grappling with rivals during mating. Fly fishers prize hellgrammites as bait because their presence signals healthy, well-oxygenated water.
17. Eastern Fence Lizard
The eastern fence lizard (Sceloporus undulatus) is a small, spiny-scaled reptile often spotted clinging to tree trunks, fence posts, and woodpiles across the eastern and central United States. Males flash bright blue patches on their throats and bellies during territorial displays, doing push-up-like movements to show off the color to rivals and potential mates. These lizards bask openly in sunny patches to regulate body temperature before darting after insects.
18. Eastern Glass Lizard
The eastern glass lizard (Ophisaurus ventralis) looks remarkably like a snake, but a closer look reveals the telltale signs of a legless lizard, including movable eyelids and visible ear openings. When grabbed, it can detach part of its tail in a defense called autotomy, a trick that gives the species its “glass” nickname since the tail appears to shatter away. The detached tail segment continues to wriggle, distracting predators while the lizard escapes to safety.
19. Eastern Gorilla
The eastern gorilla (Gorilla beringei) is the largest living primate, with adult males sometimes weighing over 400 pounds in the mountain forests of central Africa. Despite their imposing size, eastern gorillas are predominantly herbivorous, spending much of each day foraging for leaves, stems, and fruit within tight-knit family groups led by a dominant silverback. Habitat loss and poaching have pushed the species to critically endangered status, with ongoing conservation efforts in Rwanda, Uganda, and the Democratic Republic of the Congo.
20. Eastern Gray Squirrel
The eastern gray squirrel (Sciurus carolinensis) is one of the most recognizable backyard mammals in North America, equally at home in city parks and deep forests. Each squirrel buries thousands of nuts every autumn in a practice called scatter hoarding, and research shows they rely heavily on spatial memory and smell to relocate their caches months later. Introduced populations have also become established in parts of Europe, where they sometimes outcompete native red squirrels for food and territory.
21. Eastern Green Mamba
The eastern green mamba (Dendroaspis angusticeps) is a slender, vividly green snake that spends most of its life in the forest canopy of East Africa, rarely descending to the ground. Its coloration provides near-perfect camouflage among leaves, making encounters with humans uncommon despite the snake’s potent neurotoxic venom. Eastern green mambas are shy by nature, preferring to flee through branches rather than confront a threat.
22. Eastern Hognose Snake
The eastern hognose snake (Heterodon platirhinos) is famous for one of the most theatrical defense displays in the reptile world. When threatened, it flattens its body, hisses loudly, and may strike with a closed mouth to appear venomous. If that bluff fails, the snake flips onto its back, convulses, and plays dead, often with its tongue hanging out, until the danger passes. This harmless species primarily eats toads, using enlarged rear teeth to help deflate them during swallowing.
23. Eastern Indigo Snake
The eastern indigo snake (Drymarchon couperi) is the longest native snake species in the United States, with some individuals reaching over eight feet. Its scales reflect a deep, iridescent blue-black sheen in sunlight, giving the species its name. Eastern indigo snakes are immune to the venom of many of the pit vipers they share habitat with and are known to prey on rattlesnakes, making them an important natural check on venomous snake populations in longleaf pine ecosystems.
24. Eastern Lowland Gorilla
The eastern lowland gorilla, or Grauer’s gorilla (Gorilla beringei graueri), is a subspecies of the eastern gorilla found in the lowland and montane forests of the eastern Democratic Republic of the Congo. It is the largest of all gorilla subspecies, and decades of regional conflict have made population monitoring difficult, though surveys suggest numbers have dropped sharply since the 1990s. Bushmeat hunting and habitat disruption from mining remain the most pressing threats to its survival.
25. Eastern Screech Owl
The eastern screech owl (Megascops asio) is a small, well-camouflaged owl that relies on gray or reddish-brown plumage to blend seamlessly into tree bark during the day. Despite its name, the species doesn’t actually screech; its call is a descending, whinny-like trill often mistaken for a small horse. Eastern screech owls are cavity nesters, frequently taking over old woodpecker holes in suburban yards as readily as deep forest.
26. Eastern Woodrat
The eastern woodrat (Neotoma floridana) builds elaborate stick nests, sometimes called pack rat middens, that can be reused and expanded by generations of the same family line over many years. These nests often incorporate found objects, shiny trinkets, and food caches, and some middens have been studied by scientists for the ancient plant material preserved inside. Eastern woodrats are primarily herbivorous, foraging on nuts, fungi, and green vegetation near rocky outcrops and forest edges.
27. Echidna
The short-beaked echidna (Tachyglossus aculeatus) is one of only five living species of monotreme, the small group of mammals that lay eggs instead of giving live birth. Covered in sharp spines similar to a hedgehog’s, an echidna curls into a tight ball when threatened and can also dig itself into the ground with surprising speed. Alongside the platypus covered in our animals that start with P guide, the echidna represents one of evolution’s strangest surviving branches.
Key Insight: Monotremes split from other mammals more than 150 million years ago, meaning echidnas and platypuses retain reptile-like traits such as egg-laying that disappeared from every other living mammal lineage.
28. Eel
True eels, represented by species such as the European eel (Anguilla anguilla), live one of the most mysterious life cycles in the animal kingdom. They begin life as tiny larvae in the open ocean, drift for months or years toward coastal rivers, then spend most of their adult lives in fresh water before making one final migration back to the sea to spawn and die. Their long, serpentine bodies allow them to wriggle through mud, gravel, and even damp grass when moving between bodies of water.
29. Egret
The great egret (Ardea alba) is a tall, elegant wading bird found near wetlands, rivers, and coastlines on every continent except Antarctica. During breeding season, egrets grow long, delicate plumes once so prized by the fashion industry that overhunting nearly wiped out some populations in the early 20th century, spurring the creation of some of the first modern bird protection laws. Like the wading birds in our bird names that start with I list, egrets hunt by standing motionless in shallow water before striking at fish with lightning speed.
30. Egyptian Mau
The Egyptian Mau is a naturally spotted domestic cat breed (Felis catus) believed to descend from ancient Egyptian cats, and its name comes from the Egyptian word for cat. Unlike many spotted cat breeds that achieved their pattern through crossbreeding with wild species, the Mau’s rosettes are a naturally occurring trait passed down through centuries. The breed is known for strong hind legs and remarkable speed, with some sources crediting it as one of the fastest domestic cat breeds.
31. Egyptian Vulture
The Egyptian vulture (Neophron percnopterus) is a smaller, more slender relative of the large vultures covered in our animals that start with V guide, and it stands out for a remarkable tool-use behavior. It is one of the few birds known to use tools in the wild, picking up stones and dropping them onto thick-shelled ostrich eggs to crack them open for food. Once common across Europe, the Middle East, and Africa, the species has suffered sharp population declines from poisoning and habitat loss, earning it endangered status on the IUCN Red List.
32. Eider
The common eider (Somateria mollissold mollissima) is a large sea duck found along northern coastlines in Europe, Asia, and North America, prized historically for the exceptional insulating quality of its down feathers. Eiders dive to the seafloor to pry mussels and other shellfish loose, swallowing them whole and crushing the shells in a muscular gizzard. Females incubate their eggs using down plucked from their own breasts, a practice humans later adapted for eiderdown bedding.
33. Eland
The common eland (Taurotragus oryx) is the second-largest antelope species in the world, with spiraled horns and a muscular build that can make bulls weigh close to a ton. Despite their bulk, elands are surprisingly agile jumpers, capable of clearing fences over eight feet tall when startled. Much like the large grazing bovids featured in our animals that start with Y list, elands roam open savanna and woodland across southern and eastern Africa in loose herds.
34. Electric Eel
Despite its name, the electric eel (Electrophorus electricus) is not a true eel at all but a knifefish related to catfish and carp. Roughly 80 percent of its body is made up of specialized electric organs capable of generating shocks exceeding 600 volts, used both to stun prey and to navigate murky Amazonian waters where vision is nearly useless. A single electric eel can discharge repeated pulses in rapid succession, a strategy researchers believe may have helped inspire early designs for the electric battery.
35. Elephant
The African bush elephant (Loxodonta africana) is the largest living land animal, with bulls capable of weighing over six tons. Elephants are famed for complex social bonds, long memories, and the ability to communicate over long distances using low-frequency rumbles that travel through both air and ground. A single adult elephant can consume hundreds of pounds of vegetation a day, making the species a keystone force in shaping savanna and forest ecosystems.
| Animal | Typical Weight | Habitat | Notable Trait |
|---|---|---|---|
| Elephant (Loxodonta africana) | Up to 6+ tons | African savanna and forest | Largest living land animal |
| Elephant Seal (Mirounga leonina) | Up to 4 tons (males) | Sub-Antarctic beaches | Largest living seal species |
| Emperor Penguin (Aptenodytes forsteri) | Up to 90 lbs | Antarctic ice and sea | Tallest, heaviest penguin species |
| Electric Eel (Electrophorus electricus) | Up to 44 lbs | Amazon basin rivers | Generates shocks over 600 volts |
36. Elephant Seal
The southern elephant seal (Mirounga leonina) is the largest living seal species, with bulls able to reach nearly four tons thanks to a trunk-like nose used to amplify roaring calls during breeding season battles. Like the pinnipeds covered in our animals that start with W list, elephant seals can dive to extraordinary depths, with some individuals recorded descending beyond 1,500 meters in search of squid. They spend most of the year alone at sea, gathering on beaches only to breed and molt.
37. Elephant Shrew
Elephant shrews, also called sengis, are small, long-snouted mammals native to Africa that are surprisingly unrelated to true shrews covered in our animals that start with S guide, belonging instead to a distinct order more closely tied to elephants and manatees. The round-eared sengi (Macroscelides proboscideus) uses its flexible, trunk-like nose to probe leaf litter for insects, often covering impressive distances for its tiny size while foraging. Despite the name, elephant shrews are monogamous and form long-term pair bonds that defend shared territories.
38. Elf Owl
The elf owl (Micrathene whitneyi) is the smallest owl species in the world, weighing barely more than a handful of coins and standing roughly as tall as a soda can. This tiny nocturnal hunter nests almost exclusively in cavities carved by woodpeckers in saguaro cacti and desert trees across the southwestern United States and Mexico. Despite its size, the elf owl is a capable predator of scorpions, moths, and other desert insects, much like the other nighttime hunters profiled in our bird names that start with Z list.
39. Elk
The elk, or wapiti (Cervus canadensis), is one of the largest members of the deer family, and bull elk produce a haunting, high-pitched bugle call during autumn mating season that can carry for miles across mountain valleys. Like the large cervids profiled in our animals that start with R list, elk undertake seasonal migrations between high-elevation summer range and lower winter grounds. Bulls grow and shed a new set of antlers every year, with mature males sometimes carrying racks weighing over 40 pounds.
40. Emerald Cockroach Wasp
The emerald cockroach wasp (Ampulex compressa) is a small, metallic-green insect with one of the most unsettling reproductive strategies in nature. The female stings a cockroach twice, first to temporarily paralyze its legs, then with a precisely targeted sting into the brain that suppresses its escape reflex. She then leads the docile cockroach, like a pet on a leash, into a burrow where her larva will eventually hatch and feed on it from the inside.
41. Emperor Angelfish
The emperor angelfish (Pomacanthus imperator) is a strikingly patterned reef fish found throughout the Indo-Pacific, instantly recognizable by its bold blue and yellow horizontal stripes. Juveniles look almost nothing like adults, sporting concentric blue and white circles instead of stripes, a disguise that may help them avoid aggression from territorial adult angelfish. These fish graze on sponges and algae along coral reefs, playing a small but steady role in reef health.
42. Emperor Goose
The emperor goose (Anser canagicus) breeds along the remote coastal tundra of Alaska and the Russian Far East, standing out among waterfowl for its silvery-gray plumage scalloped with black edging. Unlike many geese that migrate long distances inland, emperor geese tend to stay close to coastal and estuarine habitats year-round. Local Alaska Native communities have long relied on traditional, carefully regulated harvests of the species, which helped inform modern conservation management after population declines in the late 20th century.
43. Emperor Newt
The emperor newt (Tylototriton shanjing) is a strikingly colored amphibian native to the mountain forests of Yunnan Province in China, easily identified by its black body and bright orange ridges along the head, limbs, and tail. Like many brightly colored amphibians, its coloration serves as a warning to predators that its skin secretes mild toxins. Emperor newts spend much of the year on land, returning to slow-moving streams and ponds only during the breeding season.
44. Emperor Penguin
The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species, standing around four feet tall and built to endure some of the harshest winters on Earth. Unlike most birds, emperor penguins breed during the brutal Antarctic winter, with males incubating a single egg on their feet for roughly two months without eating while huddling in massive colonies for warmth. Chicks are raised entirely on sea ice, with parents taking turns trekking dozens of miles to open water to find food.
Pro Tip: Emperor penguins are often confused with the slightly smaller king penguin. A quick way to tell them apart is the emperor’s larger size and the sharper, yellow-to-white gradient on its neck patches.
45. Emperor Tamarin
The emperor tamarin (Saguinus imperator) is a small South American monkey famous for a long, flowing white mustache that reportedly inspired its name as a nod to a German emperor’s similarly dramatic facial hair. These primates live in small family troops in the rainforest canopy of the western Amazon basin, communicating through a wide range of chirps and whistles. Emperor tamarins typically give birth to twins, with the father and other group members sharing infant-carrying duties.
46. Emu
The emu (Dromaius novaehollandiae) is the second-tallest living bird after the ostrich, and like the flightless giant covered in our animals that start with O list, it has traded flight for powerful legs built for covering long distances across the Australian outback. Emus can sprint at speeds up to 30 miles per hour and are strong swimmers when crossing rivers. In an unusual twist among birds, the male emu takes over nearly all incubation and chick-rearing duties after the female lays her eggs.
47. English Angora Rabbit
The English Angora rabbit (Oryctolagus cuniculus) is a domestic breed prized for an extraordinarily thick, silky wool coat that can grow several inches long if left untrimmed. Unlike the wild cottontails and hares profiled in our animals that start with R list, English Angoras require regular grooming to prevent painful matting and are commonly kept for their fiber, which is spun into luxury yarn. The breed’s fluffy face and ear tufts give it a distinctly ornamental appearance among rabbit breeds.
48. English Bulldog
The English Bulldog is a stocky, short-muzzled dog breed known for a loose, wrinkled face and a famously laid-back temperament. Originally bred in England for the brutal sport of bull-baiting before the practice was banned in the 19th century, the breed was gradually reshaped into the gentler companion dog recognized today. Its distinctive flat face, a trait called brachycephaly, means the breed is prone to breathing difficulties in hot weather and benefits from careful temperature management.
49. English Cocker Spaniel
The English Cocker Spaniel is a medium-sized sporting dog developed to flush and retrieve game birds across the English countryside, a role that still shapes its high energy and keen nose today. Slightly taller and leaner than its American Cocker Spaniel cousin, the breed carries long, silky ears and a merry, ever-wagging tail that has become something of a breed trademark. English Cocker Spaniels thrive with daily exercise and tend to form strong bonds with their families.
50. English Crested Guinea Pig
The English Crested Guinea Pig (Cavia porcellus) is a smooth-coated breed distinguished by a single rosette, or “crest,” of reversed fur in the center of its forehead, usually in a contrasting color to the rest of its coat. This small cavy breed is otherwise similar in temperament to other short-haired guinea pigs, social, vocal, and happiest living in pairs or small groups. Breeders prize the crest as the defining feature separating it from the otherwise identical American Crested variety, which requires a crest matching the body color.
51. English Foxhound
The English Foxhound is a scent hound bred over centuries in England for the specific stamina and pack cooperation needed to pursue foxes across long cross-country hunts. Built with a deep chest and powerful legs, the breed can maintain a steady running pace for hours, historically trailing behind on horseback hunts that spanned entire estates. English Foxhounds are rarely kept as typical house pets today, as their intense energy and strong pack instincts suit working or kennel environments better than solitary home life.
52. English Longhorn Cattle
The English Pointer is a lean, athletic gundog developed to locate game birds and freeze in a distinctive “point” stance, nose and tail aligned toward the hidden prey, to signal hunters before the bird is flushed. This instinctive pointing behavior is so deeply ingrained that puppies often display it naturally before any formal training begins. English Pointers need substantial daily exercise and mental stimulation, making them better suited to active households than sedentary ones.
53. English Pointer
The English Setter is one of the oldest gundog breeds, with a silky, feathered coat often marked in a speckled pattern called belton, ranging from blue-flecked to orange or liver-colored ticking. Bred to locate game birds and then crouch, or “set,” low to the ground rather than point, the breed’s gentle, affectionate temperament has made it a popular family companion well beyond hunting circles. English Setters require regular coat maintenance to prevent matting around the ears and feathering.
54. English Setter
The English Shepherd is a versatile farm dog bred in England and later refined in North America for general-purpose herding, guarding, and vermin control on working farms. Unlike many single-purpose herding breeds, the English Shepherd was valued for adaptability, handling livestock, watching children, and hunting small pests all in the same day. The breed remains closely tied to its working roots, often thriving best with a job to do rather than life as a purely ornamental pet.
55. English Shepherd
The English Springer Spaniel gets its name from its traditional job of “springing,” or flushing, game birds from dense cover for hunters. Slightly larger than the Cocker Spaniel, the breed combines a sturdy, athletic build with the same friendly, eager-to-please temperament that has made spaniels popular family dogs for generations. English Springer Spaniels require regular exercise to match their working-dog energy, even in households that never go hunting.
56. English Springer Spaniel
The English Toy Terrier is a small, sleek, black-and-tan breed descended from the same ratting terrier stock that once worked in English factories and homes to control rodent populations. Despite its diminutive size, the breed retains a sharp, alert temperament and a surprising amount of terrier tenacity for its compact frame. English Toy Terriers are considered a relatively rare breed today, with far smaller numbers than many other historic terrier lines.
Pro Tip: When comparing working and companion dog breeds, energy level matters more than size. A small, intense terrier like the English Toy Terrier can need just as much mental stimulation as a much larger working dog.
57. English Toy Terrier
The Entlebucher Mountain Dog is the smallest of the four Swiss mountain dog breeds, developed to herd cattle and guard farms in the Swiss Alps. Its tricolor coat and sturdy, muscular build echo its larger cousins, but the breed’s compact size made it especially practical for nimble work moving livestock through narrow mountain pastures. Much like the working and herding breeds covered in our dog breeds that start with R guide, Entlebuchers are intelligent, energetic dogs that need a clear job or consistent exercise routine.
58. Entlebucher Mountain Dog
The Epagneul Pont Audemer is a rare French spaniel breed named for the Normandy town where it was developed, prized historically for retrieving waterfowl from marshes and ponds. Its curly, water-resistant coat is a defining feature that sets it apart from most other spaniel breeds, giving it strong protection against cold, wet hunting conditions. The breed remains uncommon outside France, where dedicated enthusiasts continue to preserve its working lineage.
59. Epagneul Pont Audemer
The ermine (Mustela erminea), also known as the stoat, is a slender, fast-moving mustelid famous for a seasonal coat change that turns its brown summer fur almost pure white in winter, aside from a black-tipped tail. This same winter coat was historically harvested for luxury fur trim used on royal robes across Europe. Fierce for its size, the ermine can take down prey several times its own body weight, a trait shared with other small predators profiled in our animals that start with W list.
60. Ermine
The Canadian Eskimo Dog is one of the oldest and rarest Arctic sled dog breeds, developed over thousands of years by Inuit communities for pulling heavy loads across sea ice and tundra. Exceptionally strong and endurance-built, the breed was historically essential to survival and transportation across the Canadian Arctic before snowmobiles became widespread. Today, the breed’s numbers have dropped sharply, and conservation groups actively work to maintain its remaining bloodlines.
61. Eskimo Dog
The Eskipoo is a modern crossbreed combining the American Eskimo Dog and the Poodle, typically inheriting a soft, curly-to-wavy coat along with a playful, alert temperament from both parent breeds. Because Eskipoos are a mixed rather than standardized breed, size and coat texture can vary noticeably between individual litters. The cross is popular among owners seeking a companion dog with the Poodle’s lower-shedding coat combined with the American Eskimo Dog’s affectionate, family-oriented personality.
62. Eskipoo
The Española giant tortoise (Chelonoidis hoodensis) is a Galapagos subspecies that came perilously close to extinction in the mid-20th century, with only around a dozen individuals remaining in the wild by the 1960s. A captive breeding program using the surviving tortoises, including a famous male named Diego, successfully rebuilt the wild population to over 2,000 individuals before the last breeding tortoises were released back onto Española Island. The species carries a distinctive saddleback shell shape, an adaptation that lets it stretch its neck higher to reach sparse vegetation on its arid home island.
Key Insight: The Española giant tortoise recovery is considered one of conservation’s great success stories, showing how a tiny founder population can rebuild an entire subspecies with sustained captive breeding effort.
63. Española Giant Tortoise
The Estrela Mountain Dog is a large, powerfully built livestock guardian breed from Portugal’s Serra da Estrela mountains, historically tasked with protecting sheep flocks from wolves. Its thick double coat, available in short or long varieties, provides insulation against harsh mountain winters while its calm but fiercely protective temperament makes it an effective guardian. Despite its imposing size, the breed is known to be notably gentle and patient with the families and livestock it considers its own.
64. Estrela Mountain Dog
The Ethiopian wolf (Canis simensis) is Africa’s most endangered carnivore and the rarest canid species on the planet, found only in a handful of isolated highland pockets of Ethiopia above roughly 3,000 meters. Its range is limited to seven isolated mountain ranges at altitudes of 3,000–4,500 meters, with the overall adult population estimated at 360–440 individuals, more than half concentrated in the Bale Mountains. Though these rare wolves are solitary hunters, they live in packs of 3–17 individuals at high densities defending exclusive territories centred around a dominant breeding pair, a social structure that helps the species specialize almost entirely on hunting Afroalpine rodents.
Important Note: Major threats to the Ethiopian wolf include habitat loss and fragmentation due to agriculture and overgrazing, disease outbreaks, road kills, and persecution. Among endangered animals starting with E, the Ethiopian wolf remains one of the most closely monitored, with conservationists vaccinating domestic dogs near wolf habitat to prevent rabies outbreaks from spreading into remaining packs.
65. Ethiopian Wolf
The Eurasian beaver (Castor fiber) was hunted to near extinction across much of Europe by the early 20th century for its fur and scent glands, but reintroduction programs over the past several decades have returned it to rivers in Britain, Germany, and beyond. Much like the semi-aquatic rodents covered in our animals that start with N list, Eurasian beavers reshape entire landscapes by building dams that create wetlands, which in turn boost biodiversity for fish, birds, and amphibians. A single beaver family can fell dozens of trees a year to maintain its lodge and dam system.

The Eurasian jay (Garrulus glandarius) is a strikingly patterned woodland bird with a pinkish-brown body, a bold black mustache mark, and flashes of electric blue on its wings. Jays are prolific acorn hoarders, burying thousands each autumn and inadvertently helping to plant new oak forests across their range in Europe and parts of Asia. Highly intelligent, Eurasian jays can mimic other birds’ calls and even imitate human voices in captivity.
67. Eurasian Jay
The Eurasian lynx (Lynx lynx) is the largest lynx species in the world, built with long legs, tufted ears, and broad paws that act like natural snowshoes across its forested range from Western Europe to Siberia. Much like the bobcat profiled in our animals that start with B list, the Eurasian lynx is a solitary, stealthy hunter relying on ambush rather than long chases to take down roe deer and other prey. Reintroduction efforts have slowly expanded its range back into parts of Central Europe where it had vanished.
68. Eurasian Lynx
The Eurasian red squirrel (Sciurus vulgaris) is native to forests across Europe and parts of Asia, easily recognized by its reddish coat and prominent ear tufts that grow thicker in winter. Populations in the United Kingdom and parts of Ireland have declined sharply over the past century due to competition from introduced eastern gray squirrels and a squirrelpox virus that gray squirrels carry without harm but that proves fatal to reds. Conservation efforts now focus on protecting isolated red squirrel strongholds from further gray squirrel encroachment.
69. Eurasian Red Squirrel
The Eurasian wolf (Canis lupus lupus) is the most widely distributed wolf subspecies, ranging historically from Western Europe across Russia into parts of East Asia. Slightly smaller on average than North American gray wolves, Eurasian wolves form tight family packs led by a breeding pair and communicate through howls that can carry for miles across open terrain. After near-eradication across much of Western Europe by the mid-20th century, natural recolonization and legal protections have allowed populations to rebound in countries including Germany, France, and Poland.
70. Eurasian Wolf
The Eurasier is a German breed developed in the mid-20th century by deliberately crossing the Wolfspitz, Samoyed, and Chow Chow to produce a calm, family-oriented companion dog. Unlike its more high-strung spitz ancestors, the Eurasier was specifically bred for a gentle, even temperament, making it well suited to households seeking a loyal but low-drama dog. The breed’s thick double coat and reserved-but-affectionate nature have made it increasingly popular beyond its native Germany.
71. Eurasier
The European badger (Meles meles) lives in complex underground burrow systems called setts, which can be passed down and expanded by generations of the same badger clan for over a century. Unlike the solitary American badger, European badgers are highly social, often living in small family groups that share grooming duties and sleeping chambers. Much like the wolverine covered in our animals that start with W list, badgers are powerful diggers with a varied diet that includes earthworms, small mammals, and fruit.
72. European Badger
The European edible dormouse (Glis glis), also called the fat dormouse, spends up to seven months of the year in deep hibernation, one of the longest sleep periods of any mammal. Much like the smaller dormice covered in our animals that start with D list, this species bulks up significantly on nuts and seeds before winter, sometimes doubling its body weight to survive the long dormant period. Ancient Romans reportedly considered the species a delicacy, which is the origin of its unusual common name.
73. European Edible Dormouse
The European goldfinch (Carduelis carduelis) is a small, vividly colored finch with a bright red face and golden-yellow wing bars that make it one of the more eye-catching garden birds across Europe, North Africa, and parts of western Asia. Flocks of goldfinches are traditionally called a “charm,” a nod to their musical, twittering calls. These birds specialize in extracting seeds from thistles and teasels using a uniquely narrow, pointed beak suited to reaching deep into spiky seed heads.
74. European Goldfinch
The European mink (Mustela lutreola) is one of the most endangered mammals in Europe, having disappeared from roughly 90 percent of its historic range due to competition and disease from the larger, introduced American mink. This semi-aquatic hunter relies on rivers, streams, and wetlands, feeding on fish, amphibians, and small mammals along the water’s edge. Conservation breeding programs in several European countries now aim to establish mink populations on predator-free islands, isolated from American mink competition.
75. European Mink
The European polecat (Mustela putorius) is the wild ancestor of the domestic ferret and shares its relative’s musky scent glands, used both for marking territory and as a defense against predators. Once persecuted heavily as a perceived threat to game and poultry, polecats have recovered strongly across much of Britain and continental Europe in recent decades thanks to legal protection. These nocturnal hunters prey heavily on rabbits, rodents, and amphibians within hedgerows and woodland edges.
76. European Polecat
The European robin (Erithacus rubecula) is a small, round songbird with an unmistakable orange-red breast, celebrated across Britain as a beloved garden visitor and a familiar symbol on winter holiday cards. Unlike many songbirds, European robins are fiercely territorial year-round and will aggressively defend their patch even against much larger intruders. Both males and females sing, a relatively unusual trait among European songbirds, which helps them hold separate territories through the winter months.
77. European Robin
The European tree frog (Hyla arborea) is a small, bright green amphibian equipped with sticky toe pads that allow it to climb smooth leaves, branches, and even glass with ease. Males produce a surprisingly loud, rasping call during breeding season that can be heard from considerable distances despite the frog’s tiny size, often just a couple of inches long. European tree frogs are sensitive indicators of wetland health, and population declines in parts of their range have been linked to habitat drainage and pollution.
78. European Tree Frog
The European wildcat (Felis silvestris) looks remarkably similar to a striped domestic tabby, but it is a genuinely wild species with a thicker, bushier ringed tail and a far more solitary, elusive nature. Much like the larger wild felids profiled in our animals that start with T list, European wildcats are strictly territorial, ambush hunters that avoid human contact whenever possible. Hybridization with free-roaming domestic cats has become one of the biggest threats to the genetic integrity of remaining wildcat populations in parts of Scotland and continental Europe.
Key Insight: Because European wildcats interbreed readily with domestic cats, conservationists now consider genetic “purity” screening just as important as habitat protection for preserving the species long term.
79. European Wildcat
The evening bat (Nycticeius humeralis) is a small, fast-flying insect-eating bat common across the southeastern and central United States, emerging shortly after sunset to hunt beetles, moths, and other flying insects over fields and woodland edges. Maternity colonies can number in the hundreds, with females forming tight nursery roosts in tree cavities or buildings to raise pups communally. A single evening bat can consume a substantial portion of its body weight in insects each night, making the species a valuable natural pest-control ally for farmers.
80. Evening Bat
The eyed click beetle (Alaus oculatus) is named for the pair of large, dark, eye-like spots on its thorax, a bluffing pattern that makes the harmless insect look far more intimidating to predators than it actually is. If flipped onto its back, the beetle can snap a spring-loaded joint between its thorax and abdomen with an audible click, flinging itself into the air to right itself again. This same clicking mechanism also startles would-be predators long enough for the beetle to make its escape.
81. Eyed Click Beetle
The eyelash viper (Bothriechis schlegelii) is a small, arboreal pit viper found in the rainforests of Central and South America, named for the distinctive scales above its eyes that resemble long eyelashes. The species comes in a striking range of color morphs, from mossy green to vivid yellow, which help it blend into the specific foliage of its home range while it waits motionless for passing frogs, lizards, and small birds. Although rarely fatal to healthy adults, its venom can cause significant local tissue damage, and any bite should be treated as a medical emergency.
From the tallest eagle’s-eye view of a mountain valley to the smallest click beetle flipping itself out of danger, this E animals list shows just how much variety one letter of the alphabet can hold. Several entries on this page, including the Ethiopian wolf, the Española giant tortoise, and the European mink, remain active conservation priorities, a reminder that even well-known-sounding names can belong to genuinely rare creatures. Readers curious about other letters can continue the alphabet with lists covering animals that start with D, animals that start with S, or animals that start with W for more species worth discovering.
