Key takeaways

Chester Zoo in the UK recently announced the birth of Rana, a rare babirusa piglet, bringing attention to this threatened Indonesian species.
The babirusa is endemic strictly to four Indonesian islands, namely Sulawesi, Togian, Sula, and Buru.
Classified as Vulnerable on the IUCN Red List, the species faces severe threats from African swine fever, habitat loss, and hunting.
Female babirusas give birth to only 1 to 2 piglets per litter after a gestation period of 155 to 161 days.

Chester Zoo in the UK recently announced the birth of a rare babirusa piglet named Rana.
Wild populations of this species are currently declining due to African swine fever, habitat loss, and hunting across Indonesia.

The babirusa (genus Babyrousa) is commonly referred to as the pig-deer and represents one of the oldest wild pig species.
The name babirusa comes from the Malay language, reflecting its distinct physical appearance and stag-like upper tusks.
This species is strictly endemic to four islands in Indonesia: Sulawesi, Togian, Sula, and Buru.
It inhabits tropical rainforests, swamps, and wetlands, preferring areas near riverbanks and natural ponds rich in aquatic plants.
The species is currently classified as Vulnerable on the IUCN Red List of Threatened Species.

Male babirusas have upper canine teeth that grow upward, pierce through the skin of their snout, and curve backward toward the forehead.
Female babirusas give birth to only 1 to 2 piglets per litter after a gestation period of 155 to 161 days.
They feature barrel-shaped bodies covered in sparse grey-brown skin, and newborn piglets uniquely lack protective camouflage stripes.
They are active omnivores that use hooves to dig for roots, stand on hind legs to reach high leaves, and run at speeds up to 30 mph.
They communicate using grunts and tooth-clattering, and display a unique ploughing behavior by pushing their heads through soft sand.

Babirusas play an important role in seed dispersal and forest regeneration, serving as key indicators of overall ecosystem health.
They belong to an ancient lineage depicted in prehistoric Indonesian cave art, and captive breeding helps protect their genetics from extinction.
