What are all the fossa?

The term "fossa" can refer to two different contexts: a genus of carnivorous mammals native to Madagascar, specifically the Cryptoprocta ferox, which resembles a small cougar and is the island's top predator; or to anatomical depressions or cavities in various organisms, such as the fossa ovalis in the human heart. In the context of anatomy, fossae (plural of fossa) serve various functions, including housing nerves or blood vessels. If you meant a specific type of fossa, please clarify!
