The spotted hyena’s famous “laugh” is actually a sound made to alert other group members to a source of food. This noise can be heard up to three miles away, and is one of many sounds made by this sociable species to communicate with each other.
Hyenas are skilled hunters as well as scavengers, and their large, powerful jaws allow them to chomp through every part of their prey, including the skin and bones. The only parts which cannot be digested are hair, horns and hooves - the hyena will regurgitate these in pellets.
Hyenas are found in many habitats, including woodland, savannah and desert, though being nocturnal, they are rarely observed. Human-wildlife conflict has long been a problem. Hyenas are known to have eaten people, though it is more likely that they will kill livestock, which results in them being targeted by hunters.
