Babirusa Babirusa The babirusas, also called deer-pigs () are a genus, Babyrousa, in the swine family found in Wallacea, or specifically the Indonesian islands of Sulawesi, Togian, Sula and Buru. All members of this genus were considered part of a single species until 2002, the babirusa, "B. babyrussa", but following the split into several species, this scientific name is restricted to the Buru babirusa from Buru and Sula, whereas the best-known species, the north Sulawesi babirusa, is named "B. celebensis". The remarkable "prehistoric" appearance of these mammals is largely due to the prominent upwards incurving canine tusks of the males, which

However, in 2003, the International Commission on Zoological Nomenclature decided that the scientific names of the wild species have priority over the scientific names of domesticated species, therefore mandating the use of "Equus ferus" for the horse, independent of the position of the domesticated horse. Przewalski's horse occupied the eastern Eurasian Steppes, perhaps from the Urals
