Origin: [L., a ditch. See Fosse.]
The fossa is a cat-like, carnivorous mammal that is endemic to Madagascar. It is a member of the Eupleridae, a family of carnivorans closely related to the mongoose family. Its classification has been controversial because its physical traits resemble those of cats, yet other traits suggest a close relationship with viverrids. Its classification, along with that of the other Malagasy carnivores, influenced hypotheses about how many times mammalian carnivores have colonized the island. With genetic studies demonstrating that the fossa and all other Malagasy carnivores are most closely related to each other, carnivorans are now thought to have colonized the island once around 18 to 20 million years ago. The fossa is the largest mammalian carnivore on the island of Madagascar and has been compared to a small cougar. Adults have a head-body length of 70–80 cm and weigh between 5.5–8.6 kg, with the males larger than the females. It has semi-retractable claws and flexible ankles that allow it to climb up and down trees head-first, and also support jumping from tree to tree. The fossa is unique within its family for the shape of its genitalia, which share traits with those of cats and hyenas.
A vital or natural hollow within the body of an animal, human or mammal.
There are a variety of fossa within the human body e.g. cranial fossa any one of three hollows (anterior, middle, and posterior) in the base of the cranium for the lobes of the brain, popliteal fossa located at the posterior of the knee.
