22 Animals That Start with Z: Wild, Domestic, and Hybrid Species from Zander to Zuchon
October 24, 2026
Animals that start with Z are scarce in English, and most borrow their names from one famous striped grazer. Outside the animals with “zebra” in the name, the letter has few entries. Even the borrowed names can mislead. The zebra shark, for one, is a spotted shark, though its young have stripes.
This list covers 22 animals: freshwater predators, island primates, burrowing rodents, domestic cattle, and several hybrids that people created on purpose or by accident. Each entry has a short history, and many have a US connection. Zebra mussels clog Great Lakes pipes, zebu blood runs through Texas cattle, and zebra finches chirp in living rooms across the country.
If you are working through the alphabet, the previous page on animals that start with Y covers the letter just before this one.
1. Zander
The zander (Sander lucioperca) is a freshwater predator that European anglers often call pike-perch. It ranges across Europe and western Asia and has been introduced elsewhere. It favors large rivers, lakes, and some brackish coastal waters. Its glassy eyes help it hunt in murky water at dusk.
American anglers already know its closest relative. The walleye (Sander vitreus) belongs to the same genus and has the same reflective eyes and sharp teeth. Zander share European waters with pike and perch, which appear in our list of animals that start with P.
2. Zanzibar Leopard
The Zanzibar leopard (Panthera pardus adersi) is a leopard subspecies that lived only on Unguja, the main island of the Zanzibar archipelago off Tanzania. Islanders hunted it heavily through the 1960s and 1970s. Many people on the island believed some villagers kept leopards for witchcraft, which made the cats targets.
No living animal has been confirmed in decades, and many biologists treat the subspecies as extinct or very close to it. Reports of sightings still surface. None has produced a verified breeding population.
3. Zanzibar Red Colobus
The Zanzibar red colobus (Piliocolobus kirkii) is a monkey found only on Zanzibar, Tanzania. The species name honors Sir John Kirk, a British physician and colonial official who lived on the island in the nineteenth century and sent specimens home. Males and females carry shaggy red-brown fur with a pale belly and a black face fringed with white.
The monkeys live in the island’s forests and farm edges, including the Jozani Forest. They are best known for an odd habit: they chew charcoal from burned trees. Only a few thousand remain, and habitat loss and road deaths are the main threats.
4. Zarudny’s Jird
Zarudny’s jird (Meriones zarudnyi) is a small, gerbil-like rodent of dry steppe and desert country in Iran and neighboring Central Asia. Few photographs of it exist, so it rarely appears on animal lists. That obscurity is part of its appeal.
The jird is named for Nikolai Zarudny, a Russian ornithologist and explorer who spent years surveying Persia and Central Asia in the late nineteenth and early twentieth centuries. Like other jirds, it digs burrows that shelter it from daytime heat and eats seeds and plant matter.
5. Zebra
Zebras are wild horses’ closest striped relatives. They belong to the genus Equus, which also includes wild asses and donkeys. There are three living species, and the plains zebra (Equus quagga) is the most common. The other two are the mountain zebra (Equus zebra) and Grévy’s zebra (Equus grevyi).
| Zebra Species | Range | Distinguishing Trait |
|---|---|---|
| Plains zebra | Eastern and southern Africa | Broad stripes, compact build |
| Mountain zebra | Southwestern Africa | Dewlap under the throat, grid pattern on rump |
| Grévy’s zebra | Kenya and Ethiopia | Narrow stripes, large rounded ears, largest wild equid |
Why zebras have stripes has puzzled naturalists since Darwin’s day. Zoologist Tim Caro of the University of California, Davis, and his colleagues have argued that the pattern mostly discourages biting flies. Zebras have never been successfully domesticated, unlike their cousins the horse and donkey. Przewalski’s horses and African wild asses have not been either.
6. Zebra Duiker
The zebra duiker (Cephalophus zebra) is a small antelope endemic to Liberia, Ivory Coast, Sierra Leone, and Guinea, which prefers lowland rainforest. Its gold or red-brown body carries black stripes, which give the animal its name. The word “duiker” comes from Afrikaans for “diver,” a nod to how these antelope plunge into thick brush when startled.
Duikers are shy forest animals, and bushmeat hunting and logging have pushed the zebra duiker toward the edge. Antelope fans can compare it with others in the animals that start with D list.
7. Zebra Finch
The zebra finch is a small, chattering songbird. Two species exist, the Sunda zebra finch and the Australian zebra finch. They were once classed as one species before ornithologists divided them. The familiar pet-store bird is the Australian form (Taeniopygia castanotis), while the Sunda form is Taeniopygia guttata. It is native to Australia and commonly lives in dry grasslands and open areas.
In the United States, zebra finches are among the most common pet birds, and they are a mainstay of neuroscience labs. Young males learn their songs by copying an adult tutor, much as human infants learn speech. Readers who enjoy birds can browse more names in our bird names that start with Z guide.
8. Zebra Mussel
The zebra mussel (Dreissena polymorpha) is a thumbnail-sized, striped mollusk. It is native to the Black and Caspian sea region and is now an invasive species in North America. Scientists first found it in Lake St. Clair in 1988. Ships probably carried it in ballast water from Europe.
From the Great Lakes, zebra mussels spread through the Mississippi River system and, in 2007, reached Lake Mead in Nevada. They filter huge volumes of water, which clears lakes but starves native plankton feeders. They also coat water intake pipes, boat hulls, and native mussel shells.
Pro Tip: Boaters can slow the spread by cleaning off plants and mud, draining all water from the boat and gear, and letting everything dry before moving to another lake. Many state wildlife agencies publish these steps as “Clean, Drain, Dry.”
9. Zebra Pleco
The zebra pleco (Hypancistrus zebra) is a small, black-and-white striped armored catfish. It is a freshwater catfish endemic to the Xingu River in Brazil. That single river is the only natural home it has, which makes the species vulnerable to dams and habitat change.
Aquarists prize it, and fish with such tiny ranges often sell for high prices. Brazil regulates the collection of wild specimens, so captive breeding supplies much of the aquarium trade. Hobbyists in the US keep it in warm, well-oxygenated tanks with caves for shelter.
10. Zebra Shark
The zebra shark (Stegostoma tigrinum) is a slow, bottom-dwelling shark with a tail nearly as long as its body. Young sharks have dark stripes, which inspired the name. Adults develop leopard-like spots instead. It prefers marine waters but also lives in freshwater and brackish habitats.
Common Mistake: The zebra shark is not the leopard shark that Californians see in San Francisco Bay. That species (Triakis semifasciata) is a different animal. In Australia, though, “leopard shark” is a common alternate name for the zebra shark.
TRVST lists the zebra shark as endangered. Large public aquariums in the US exhibit the species and take part in breeding programs.
11. Zebra Spitting Cobra
The zebra spitting cobra (Naja nigricincta) lives in the dry savannas and scrublands of southwestern Africa, including Namibia and Angola. It is also called the zebra snake, after the dark bands across its body. Like other spitting cobras, it can spray venom from its fangs toward an attacker’s eyes.
The spray does little harm on intact skin, but venom in the eyes causes intense pain. The standard first aid is to flush the eyes with plenty of water and get medical care. Zebra spitting cobras eat rodents, lizards, and toads, and they usually retreat rather than fight.
12. Zebra Tarantula
The Costa Rican zebra tarantula (Aphonopelma seemanni) is the species most people mean by this name. It is a large spider with striped legs that lives in burrows. It is native to Central America, and the pale stripes on its knees explain its other name, the striped-knee tarantula.
It is a popular pet in the US because it is hardy and relatively calm, though its hairs can irritate skin and eyes. Americans have their own tarantulas too. Several Aphonopelma species live in the Southwest and cross roads in the fall, and you can read more about them in our animals that start with T list.
13. Zebrafish
The zebrafish (Danio rerio) is a tiny minnow-relative with blue and silver stripes. It is native to South Asia. Its embryos are transparent, so scientists can watch organs form under a microscope. That trait made it a standard lab animal in medical research.
Zebrafish have another talent. They can regenerate heart tissue, and researchers are studying how to apply that to human hearts. Americans meet the species in pet stores, too, including the brightly dyed fluorescent versions sold since 2003 as GloFish. Scientists engineered those to glow under ordinary light.
Key Insight: The Z in “zebrafish” earns the animal a spot here, but its fame comes from the lab, not the wild. Few animals that start with Z have done more for human medicine.
14. Zebu
The zebu (Bos indicus) is a domestic cattle type that has a hump above its shoulders and loose skin around the neck. It originated in South Asia and has been domesticated worldwide. People raise zebu in many warm regions for milk, meat, and farm work. The hump stores muscle and fat, and the loose skin helps the animal shed heat.
Zebu shaped American ranching more than most people realize. The Brahman breed, developed in the southern United States around the turn of the twentieth century from imported zebu stock, thrives in the heat and humidity of the Gulf Coast. Texas ranchers still cross Brahman bulls with British breeds to produce heat-tolerant calves.
15. Zenaida Dove
The Zenaida dove (Zenaida aurita) is a Caribbean bird. It is about 12 inches long and eats grains, seeds, and insects. Its range covers the Caribbean and parts of the Yucatán Peninsula. It has a warm cinnamon-brown body with a bluish-gray wing patch and a white band on the wing’s rear edge.
The genus name has a romantic history. Charles Lucien Bonaparte, a French naturalist who spent years in the United States studying American birds, named Zenaida for his wife, Zénaïde. Mourning doves in American backyards belong to the same genus.
16. Zigzag Salamander
The zigzag salamander (Plethodon dorsalis) is a slim, small amphibian of the eastern United States. A reddish-orange stripe with wavy edges runs down its back and gives the animal its name. It lives on forested, rocky hillsides and around cave entrances, and spends daylight hours under logs and stones.
Like other lungless salamanders in its family, it breathes through its skin, so it needs damp ground to survive. Unlike frogs, it skips the tadpole stage, and females lay eggs on land and guard them. Hikers in the Appalachians and the Midwest are most likely to spot one after a rain.
17. Zokor
The zokor is a mole-like rodent built for tunneling. One species, the Siberian zokor (Myospalax myospalax), lives in southern Siberia and Kazakhstan. Other zokors live in China, which is why some lists place them there. They dig tunnels underground.
Zokors have tiny eyes, short fur, and long front claws, and they spend nearly their whole lives below ground. Farmers sometimes treat them as pests because they eat roots and bulbs. On the Tibetan Plateau, however, their mounds loosen soil and shape the grassland.
18. Zonkey
A zonkey is a zebra-donkey hybrid. A zonkey is a hybrid of a zebra and a donkey. Some sources call the same animal a zedonk. Most zonkeys have a donkey’s body and ears and zebra stripes on the legs and sometimes the neck.
These animals are almost always sterile. Offspring of a domestic horse and another equid, such as a zebra or a donkey, are normally sterile. The parents have different chromosome numbers, and the mismatch prevents healthy egg or sperm formation. Zonkeys turn up at small farms and zoos, where keepers often describe them as stubborn and surefooted.
19. Zorilla
The zorilla (Ictonyx striatus), also called the striped polecat, lives across sub-Saharan Africa. It is a small skunk-like mammal that sprays a strong smell when scared. It is not a skunk, though. It is a weasel relative that evolved the same black-and-white warning pattern, much as American skunks did, so predators learn to leave it alone.
It hunts at night for rodents, insects, and snakes. If a predator ignores the warning, the zorilla may play dead or spray. Comparing it with the striped skunk is easiest with our animals that start with S list.
20. Zorse
A zorse is a zebra-horse hybrid. It differs from a zonkey, which crosses a zebra and a donkey. Most zorses have a horse’s build and stripes on the legs and hindquarters. Like other horse-zebra crosses, they are almost always sterile.
The animal has a famous place in nineteenth-century science. In 1820, Lord Morton’s mare, a chestnut Arabian cross, produced a foal sired by a quagga, a now-extinct plains zebra subspecies. Her later foals by an Arabian stallion also showed faint stripes, and Charles Darwin discussed the case as evidence for “telegony,” the idea that a first mate could influence later offspring. Modern genetics rejects the idea.
Przewalski’s Horse Origins and Ancient Horse Breeds
Zorse breeding leads naturally to a question about horse history. Przewalski’s horses are critically endangered horses of Mongolia, long called the last truly wild horse. Russian explorer Nikolai Przhevalsky described the horse in 1881 after an expedition to find it. Many were captured around 1900 by Carl Hagenbeck and placed in zoos.
The animal is also the only equid that crosses fertilely with the domestic horse. Przewalski’s horse has 66 chromosomes against 64 in a domestic horse, and their offspring have 65. Today the horses live in reintroduction sites in Mongolia, China, and Kazakhstan.
Important Note: Przewalski’s horse often turns up in searches for the oldest horse breed in the world, but it is a wild lineage, not a breed. Sources also disagree on when it split from the line leading to domestic horses. The National Zoo cites mitochondrial DNA pointing to a common ancestor 500,000 years ago, while Wikipedia gives 160,000 to 38,000 years ago. Estimates vary with the method and the samples used.
The origins debate has shifted over time. For decades, scientists called the species the true wild ancestor of domestic horses, but a 2011 sequencing study found that Przewalski’s horses form their own clade, separate from the domestic lineage. A later genomic study pointed to Botai horses, which are linked to a culture of 3700 to 3100 BCE. The Smithsonian notes that some scientists see this as evidence that Przewalski’s horses may have been domesticated.
For the history of horse breeds, the best archaeology comes from Kazakhstan. The first signs of domestication, including harnessing, milking, and corralling, date to about 3500 BC at a Botai settlement. Chariot burials from about 2500 BCE give the most direct evidence of horses as working animals. Named breeds came much later, once breeders kept written pedigrees. To see how some of those breeds are catalogued, try our list of horse breeds that start with B, which includes the old North African Barb.
21. Żubroń
The żubroń is a hybrid of the European bison (Bison bonasus) and domestic cattle (Bos taurus). Its name comes from the Polish word “żubr,” meaning European bison. Polish breeders experimented with the cross in the nineteenth and twentieth centuries, near the Białowieża Forest, where the bison survived. The aim was a hardy, cold-tolerant animal with lean meat.
American ranchers ran a similar experiment on the Great Plains. In the 1880s, Texas rancher Charles Goodnight tried crossing American bison with cattle in the Panhandle, producing what became known as the cattalo. Today’s beefalo are mostly cattle with a share of bison ancestry, and they remain a niche meat product. You can compare the American bison with its European cousin in our animals that start with B list.
22. Zuchon
The Zuchon is a designer dog, a cross between a Bichon Frise and a Shih Tzu. Breeders in the United States popularized the pairing in the 2000s, and the mix goes by other names, including Shichon and Tzu Frise. Both parents are small companion dogs, and the offspring usually weigh 10 to 15 pounds with a soft, curly coat.
The American Kennel Club does not recognize the Zuchon as a breed, since mixes of two recognized breeds are considered crossbreeds. Unlike the sterile hybrids above, the Zuchon is not a cross between species. Both parents are domestic dogs (Canis lupus familiaris), so Zuchon can breed with each other and with other dogs.
| Hybrid | Parents | Fertility |
|---|---|---|
| Zonkey | Zebra and donkey | Nearly always sterile |
| Zorse | Zebra and horse | Nearly always sterile |
| Żubroń | European bison and domestic cattle | Partial; male hybrids generally sterile |
| Zuchon | Bichon Frise and Shih Tzu | Fertile (same species) |
That completes the 22 animals that start with Z, from a Zanzibar cat that may be gone to a lap dog bred in American living rooms. The letter is a good reminder that few names in the animal world are what they seem: spotted sharks, skunk-like weasels, and hybrids with Polish and American histories.
