There are 127 known extant native mammalian species in Sulawesi. A large percentage, 62% (79 species) are endemic, meaning that they are found nowhere else in the world. The largest of these are the two species of anoa or dwarf buffalo. Other artiodactyl species inhabiting Sulawesi are the warty pig and the babirusas, which are aberrant pigs. The only native carnivoran is the Sulawesi palm civet (Asian palm and Malayan civets have been introduced). Primates present include a number of nocturnal tarsiers ("T. fuscus", Dian's, Gursky's, Jatna's, Wallace's, the Lariang and pygmy tarsiers) as well as diurnal macaques (Heck's, the booted, crested black, Gorontalo, moor, and Tonkean macaques). While most of Sulawesi's mammals are placental and have Asian relatives, several species of cuscus, arboreal marsupials of Australasian origin, are also present ("Ailurops ursinus" and "Strigocuscus celebensis", which are diurnal and nocturnal, respectively).
