The aardwolf generally doesn’t eat carrion like its larger cousins do—its diet mainly consists of insects (especially termites), which it catches with a long, sticky tongue.

Aardwolves have thick yellow or brown fur with dark stripes, with bushy tails and long manes that run along their necks and backs. The mane is used to make the aardwolves appear bigger and intimidate predators, since they are neither fast runners nor especially good fighters. They do have strong jaws, but their teeth have evolved for eating insects rather than attacking larger animals. They average 22–31 inches long, and weigh 15–22 pounds.

The aardwolf is nocturnal, and sleeps in underground burrows during the day. These animals are very territorial, and use scent glands to mark the area containing their dens (a mating pair may claim and rotate through multiple burrows, using only one or two at a time). The breeding season occurs in late June/early July, with a litter of 2–5 cubs born 90 days later.
