The hyena is a carnivorous mammal known for its distinctive appearance and social behavior. Found primarily in Africa and parts of Asia, hyenas are often recognized by their strong jaws and unique vocalizations, which can sound like laughter. They are divided into four species: the spotted, brown, striped, and aardwolf. Hyenas are scavengers and hunters, often working in groups called clans. Their social structure is matriarchal, with females typically being larger and more dominant than males. Despite their reputation, hyenas play a crucial role in their ecosystems by helping to control animal populations and clean up carrion.
