What are hyenas? Do they really laugh? Hyenas are dog-like mammals found in Africa and South Asia. They are mostly nocturnal, resting by day in dense vegetation.
At dusk, these expert scavengers emerge to feed on the remains of dead animals, eating body parts left by other carnivores.
Hyenas communicate with each other by leaving scent markings within their territory. Spotted hyenas also make loud, whooping calls, which sound like manic laughter, to alert others of their presence.
The spotted hyena is the largest and most powerful member of the hyena family. A pack of hyenas is intimidating enough to drive larger predators, such as lions, away from their own kill.
Spotted hyenas not only scavenge for dead animals, but also hunt live prey. When in a pack they can bring down a zebra or even a wildebeest with ease.
