The animal in these photos is a ferox which is a carnivorous mammal that are found throughout forested areas of Madagascar. It is the largest of the predatory mammals of the island. The fossa hunts small to medium sized animals, from fish to birds. It is particularly adept at hunting lemurs, and is the predominant predator of many species, with only Madagascar's large snakes and Nile crocodiles being larger. Its prehistoric ancestors reached the size of a lion.
