The fossa, Madagascar's largest native carnivore, resembles a small puma.  It has semi-retractile claws and carnassial teeth resembling those of a cat.  The fossa is quite agile; it quickly leaps from tree to tree and branch to branch, and even moves suspended below branches. The tail assists with balance and serves as a brake. The ankles on its hindfeet are “reversible,” enabling the fossa to both ascend and descend trunks head first.     

While the fossa is a very adept tree hunter and will track arboreal lemurs (its prey of choice) for long periods, it will also hunt and cover large distances on the ground.
