Hyenas groom themselves often like felids and viverrids, and their way of licking their genitals is very cat-like (sitting on the lower back, legs spread with one leg pointing vertically upward). However, unlike other feliforms, they do not "wash" their faces. They defecate in the same manner as other Carnivora, though they never raise their legs as canids do when urinating, as urination serves no territorial function for them. Instead, hyenas mark their territories using their anal glands, a trait found also in viverrids and mustelids, but not canids and felids.[29] When attacked by lions or dogs, striped[30] and brown hyenas[31] will feign death, though the spotted hyena will defend itself ferociously.[23] The spotted hyena is very vocal, producing a number of different sounds consisting of whoops, grunts, groans, lows, giggles, yells, growls, laughs and whines.[29] The striped hyena is comparatively silent, its vocalisations being limited to a chattering laugh and howling.[32]
Mating between hyenas involves a number of short copulations with brief intervals, unlike canids, who generally engage in a single, drawn out copulation.[29] Spotted hyena cubs are born almost fully developed, with their eyes open and erupting incisors and canines, though lacking adult markings.[33] In contrast, striped hyena cubs are born with adult markings, closed eyes and small ears.[34] Hyenas do not regurgitate food for their young and male spotted hyenas play no part in raising their cubs,[29] though male striped hyenas do so.[35]
The striped hyena is primarily a scavenger, though it will occasionally attack and kill any defenseless animal it can overcome,[30] and will supplement its diet with fruits.[36] The spotted hyena, though it also scavenges occasionally, is an active pack hunter of medium to large sized ungulates, which it catches by wearing them down in long chases and dismembering them in a canid-like manner. The aardwolf is primarily an insectivore, specialised for feeding on termites of the genus Trinervitermes and Hodotermes, which it consumes by licking them up with its long, broad tongue. An aardwolf can eat 300,000 Trinervitermes on a single outing.[7] Hyenas are also known for their characteristic calls which sound like laughs
