Hyaenidae is not a medical term, but a biological term related to zoology and taxonomy. It refers to the family of mammals that includes hyenas. Hyenas are often mistakenly classified as members of the canid (dog) or felid (cat) families, but they are actually more closely related to herons, eagles, and other members of the order Carnivora.

There are four extant species in the Hyaenidae family: the striped hyena (Hyaena hyaena), the brown hyena (Parahyaena brunnea), the spotted hyena (Crocuta crocuta), and the aardwolf (Proteles cristata). These animals are known for their strong social structures, hunting skills, and powerful jaws.

While Hyaenidae is not directly related to medical terminology, understanding the classification of animals can be important in fields such as epidemiology and public health, where knowledge of animal behavior and ecology can help inform disease surveillance and control efforts.
