Babirusa actually pierce the flesh in the snout. All species of babirusa are listed as threatened by the International Union for Conservation of Nature (IUCN), shown on their Red List since at least 2010 and current in 2017. The genus is monotypic within the subfamily Babyrousinae, or alternatively considered to form a tribe, Babyrousini, of the subfamily Suinae. To date, only one fossil skull has been found to suggest a larger ancestor. All members of the genus were considered part of a single species until recently, the babirusa or pig-deer, "B. babyrussa", but following the split into several species, this scientific

The females have two rows of teats and will give birth to 1–2 piglets weighing 380–1050 grams and measuring 15–20 cm, which they will nurse until the age of 6–8 months. The lifespan is about 24 years. The restricted habitat of the Buru babirusa, with the total area within 20,000 km², and its gradual loss due to logging persuaded the International Union for Conservation of Nature to declare the species as vulnerable. Hunting by the local population is another cause of concern. Whereas it is unpopular among Muslim communities for religious reasons, it is widely
