In a study of fossa diet in the dry deciduous forest of western Madagascar, more than 90% of prey items were vertebrates, and more than 50% were lemurs. The primary diet consisted of approximately six lemur species and two or three spiny tenrec species, along with snakes and small mammals. [ 32 ]
The fossa (Cryptoprocta ferox) is a smaller relative of C. spelea that still survives.. Although some morphological differences between the two fossa species have been described, [17] these may be allometric (growth-related), and in their 1986 Mammalian Species account of the fossa, Michael Köhncke and Klaus Leonhardt wrote that the two were morphologically identical. [18]
The Malagasy or striped civet (Fossa fossana), also known as the fanaloka (Malagasy, [fə̥ˈnaluk]) or jabady, [5] is an euplerid endemic to Madagascar. [6] It is the only species in genus Fossa . The Malagasy civet is a small mammal , about 47 centimetres (19 in) long excluding the tail (which is only about 20 centimetres (7.9 in)).
Its only confirmed predators are the fossa and the bush pigs, [8] but raptors are also suspected. Protection from predators, avoiding parasite vectors, and enhanced thermoregulation are three theories that are not mutually exclusive to explain the selection of sleeping location. [9] The fossa hunts the Great bamboo lemurs in large numbers.

The traits enabled animals to check area on land for safe spots if being chased by a predator in water, as well as being useful for searching for prey items above the water. The water-based lateral line system was used substantially by these aquatic tetrapods to detect danger from predators. [ 2 ]
The wide and tall temporal fossa allowed for a very large temporalis muscle, which extends from the side of the cranium to the coronoid process of the mandible. The temporalis was not only large and strong, but also had a long moment arm (and thus higher torque) due to the coronoid process shifting forwards.
Dogs are usually cursorial mammals and are gracile in appearance, often relying on their teeth to hold prey; bears are much larger and rely on their physical strength to forage for food. Compared to dogs and bears, cats have longer and stronger forelimbs armed with retractable claws to hold on to prey. Hyenas are dog-like feliforms that have ...
