8 Desert Animals That Eat Cactus, From Javelinas to Longhorn Beetles
October 24, 2026
Desert animals that eat cactus seem to defy common sense. A prickly pear pad bristles with spines and hair-fine glochids that can lodge in skin for days. Even so, across the Sonoran, Mojave, and Chihuahuan deserts, and in the Old World deserts where camels roam, a handful of species treat the plant as both pantry and water jug.
This article profiles eight of them, from a slow-moving Mojave reptile to a beetle that spends its larval life inside the plant. Each animal has its own method for dealing with spines, and several have a human history of their own, including federal research plots, a failed military experiment, and a long run of myths.
The table below gives a quick comparison before the sections that follow.
| Animal | Cactus Part Eaten | Typical Region |
|---|---|---|
| Desert Tortoise | Pads, fruit, flowers | Mojave and Sonoran Deserts |
| Javelina | Pads and fruit | Southwestern US, Texas, Mexico |
| Coyote | Fruit and pads | Throughout North America |
| Gila Woodpecker | Fruit and nectar | Sonoran Desert |
| Arabian Camel | Pads and fruit | Arabia, North Africa |
| Desert Bighorn Sheep | Young saguaro flesh, barrel cactus | Southwestern mountains |
| Antelope Jackrabbit | Pad flesh | Southern Arizona and Sonora |
| Longhorn Cactus Beetle | Roots, stems, pads | North American deserts |
1. Desert Tortoise
The desert tortoise (Gopherus agassizii) is mainly a grazer. It burrows in the sand or rests in rock shade during hot days, and it eats grasses, wildflowers, and other plants, including cactus pads. Cactus becomes a bigger part of the menu when the rains fail.
The U.S. Geological Survey documented this with a radio-tagged male in California’s Santa Rosa Mountains. He was eating beavertail prickly pear during extreme drought, when it was the only food available with any moisture. The tortoise had to cope with the tiny glochids that cover the pads.
Tortoise science has a surprisingly precise starting date. Agassiz’s desert tortoises reach the southern edge of their mostly Mojave Desert range near Joshua Tree National Park, where modern research began in 1978 with a census of a one-square-mile area called the Barrow Plot. USGS later surveyed two western Sonoran Desert sites from 2015 to 2018 and found high female mortality during California’s 2012 to 2016 drought.
Taxonomy has shifted too. Biologists now treat the Sonoran population as a separate species, Gopherus morafkai, so the Mojave animal keeps the Agassiz name. Tortoises also spend much of the year underground, which earns them a place among the animals that sleep a lot. Readers browsing by letter will also find them among the animals that start with D.
2. Javelina
Javelinas (Pecari tajacu), also called collared peccaries, look like small wild pigs. They are not true pigs, though, and belong to the peccary family. The common name is generally traced to a Spanish word for a spear or javelin, a likely nod to their tusks.
No animal in this list is more closely tied to prickly pear. The Arizona-Sonora Desert Museum notes that javelinas eat prickly pear spines and all, tearing off bites with large canines, and because they lack sharp cutting teeth, much fibrous material stays on the pad. They chew as they walk, so scraps fall from their mouths and sometimes leave a short trail.
Texas wildlife biologists describe the technique in more detail. According to the Texas Parks and Wildlife Department, prickly pear makes up more than half of the javelina diet on most ranges. A javelina may drag a pad along the ground to break off larger thorns, pin it with a foot, and shred it between its canines.
The cactus also doubles as drinking water. Where surface water is missing, prickly pear can meet most of a javelina’s water needs, and because the cactus is low in nutrients, the animal adds mesquite beans, juniper berries, and wild grapes. Javelina kidneys also concentrate nitrogen wastes efficiently, which limits water loss, and filter out the oxalic acid found in cactus.
Important Note: Sources disagree on how to label the javelina diet. Texas Parks and Wildlife calls the animal omnivorous, while a 2013 Arizona Daily Independent natural-history piece calls javelinas herbivores. Arizona sources describe a plant-based diet with occasional insects or eggs, which is the safest summary.
Javelinas have also moved into suburbs. In developed areas they may be drawn to garbage, pet food, and bird seed, which can create conflicts with people and pets.
3. Coyote
The coyote (Canis latrans) is better known as a hunter of rodents and rabbits. Coyotes also eat snakes, a habit covered in the list of animals that eat snakes, and they share range with many of the reptiles in this roundup of snakes that live in the desert. Cactus fruit is a seasonal side dish rather than a staple.
Prickly pear is one of the plants they use. Coyotes and bobcats, along with rabbits and ground squirrels, will eat prickly pear fruit and pads when they are available. Animal Dive’s list of cactus eaters places the coyote beside the javelina, bighorn sheep, and pronghorn.
The coyote’s flexible appetite helps explain its success. The name itself comes from the Nahuatl word coyotl, and the animal appears as a trickster in many Native American stories of the Southwest. A predator that will also eat sweet, ripe tunas needs fewer lucky hunts to get through a dry summer.
4. Gila Woodpecker
The Gila woodpecker (Melanerpes uropygialis) is the bird most closely linked to the saguaro. It feeds on cactus fruits and nectar, and it excavates nests in saguaro stems. The woodpecker’s chisel work does not seem to kill the plant, since saguaros respond by sealing the wound.
That scar tissue hardens into a woody lining, often called a saguaro boot. Tohono O’odham and other desert peoples have long used the dried boots as containers. The abandoned holes then become rental housing. According to Succulent Care Hub, elf owls, screech owls, purple martins, finches, and sparrows may reuse the cavities once the woodpeckers leave.
Gila woodpeckers also hunt insects, which puts them in the same conversation as the animals that eat crickets. Their mix of fruit, nectar, and bugs lets one bird stay put in the Sonoran Desert year-round.
5. Arabian Camel
The Arabian camel (Camelus dromedarius), or dromedary, is the only Old World animal on this list. It is a large mammal with a single hump on its back, and lists of cactus eaters regularly include it. A-Z Animals ranks it first among animals that eat cactus without injury.
Camels’ leathery mouths do the protective work. Their thick lips and tough palates shield against spines. Prickly pear itself is a newcomer in the Old World, since the plant spread from the Americas to the Mediterranean and North Africa after Columbus.
The most unusual chapter happened in the United States. In the mid-1850s, the U.S. Army imported camels to Texas for desert transport, and the animals later worked survey routes across the Southwest. The Camel Corps faded out around the Civil War, but stories of stray camels in Arizona lingered for decades.
Camels in captivity eat very differently from camels in the Sahara. Zoos and farms feed them baled forage, which is why they also show up with the animals that eat hay.
6. Desert Bighorn Sheep
Desert bighorn sheep (Ovis canadensis) climb steep rock faces, but they come down for cactus. In drier parts of the Sonoran Desert, bighorn sheep, mule deer, jackrabbits, and packrats are known to eat the young flesh of the saguaro for moisture. Wildlife observers have also reported rams using horns and hooves to break into barrel cacti.
The habit matters most in summer, when springs shrink and green forage disappears. Bighorns are mainly browsers and grazers that take shrubs, grasses, and the leaves of desert plants, much like the creatures on the list of animals that eat leaves. Cactus is the emergency water supply.
Bighorn numbers fell across the West in the 1800s and early 1900s because of unregulated hunting, habitat loss, and disease passed on by domestic livestock. State wildlife agencies later moved sheep into empty ranges, and many desert herds in the Southwest descend from those transplants.
7. Antelope Jackrabbit
The antelope jackrabbit (Lepus alleni) is a hare, not a rabbit, and it is one of the most cactus-friendly hares in North America. Nimble and small-mouthed, it can eat cactus flesh while avoiding the large spines. Its range centers on southern Arizona and northwestern Mexico.
The A-Z Animals article pairs the antelope jackrabbit with a handful of other spine-proof feeders. The closely related black-tailed jackrabbit shows the family’s physical gear. Its long ears help regulate body temperature, and it can leap up to 20 feet and run up to 40 miles per hour. Another source notes that jackrabbits nibble young pads, especially after rains bring new growth.
Anyone who knows hares from cartoons may expect a carrot habit. Real jackrabbits prefer desert shrubs, grasses, and cactus, so the animals that eat carrots list has more to do with farms and gardens. Their springing gait puts them among the animals that hop.
8. Longhorn Cactus Beetle
The smallest cactus eater here is the longhorn cactus beetle (Moneilema spp.). This genus of insects feeds on and lives inside various cactus species in North American deserts. The relationship starts early. In the larval stage, the insects bore into cactus roots and stems.
Adults stay on the plant and take its tissue. They feed mostly on chollas, prickly pear, and young saguaro, and an armor-like exoskeleton lets them walk on the stems without injury. A cholla with a hollowed, wilted stem often has a beetle larva inside.
Pro Tip: Wild cactus eaters are easy to spot in the evening near washes and prickly pear patches. Keep a safe distance from javelina herds with young, and do not leave pet food outdoors.
Taken together, the eight animals show how many ways a spiny plant can feed a desert. Some chew through the spines, some avoid them, and one spends its larval life inside the stem.
