The Family Hyaenidae comprises four species of carnivorous mammals found in Africa and Asia. They are commonly known as hyenas, but there are various synonyms for this family. The subfamily Hyaeninae is sometimes used to refer specifically to the three species of hyenas, while the term "hyaena" is also used. The term "hyaenid" is sometimes used to refer to the entire family, while "hyaenoids" can be used to distinguish them from other carnivorous mammals. Additionally, the term "bone-crushing dogs" is occasionally used to describe hyenas, as they are known for their powerful jaws and ability to consume almost all parts of their prey.
