Hyenas are animals that may resemble dogs in appearance, but they are actually more closely related to cats. Spotted hyenas are the only hyenas that live in groups called clans led by the females, which grow to be bigger than the males. Hyenas come in four spieces: Spotted, Brown, Striped, and Aardwolf. Striped and brown hyenas are mostly scavengers, while spotted hyenas are primarily hunters but may also scavenge. Aardwolves eat insects, mainly termites.
