The fossa is Madagascar's largest predator. It has a flexible body, long tail, and sharp claws that allow it to climb trees well and hunt lemurs.
The fossa differs from mongooses and cats in its agility on trees and long tail. It is important for Madagascar's forests because it regulates the population of other animals.
