The animal in the video looks like a boar, but no ordinary boar has four tusks protruding from its snout. 

This is a babirusa or "deer-pig". It belongs to the swine family but looks like a deer with tusks instead of antlers. The mammal is native to a few Indonesian islands. 

The tusks give the babirusa a remarkable "prehistoric" appearance. However, only males have prominent canine tusks. 

The tusks pierce the flesh of its snout, growing outward and curving backward toward its forehead. The lower canine tusks also grow upward. 

The function of the tusks is fighting. The upper tusks are used for defense, while the lower are offensive weapons. 

If a babirusa does not grind its tusks, they keep growing to the point where they can enter its own skull. 

Despite its scary appearance, the babirusa is not an aggressive animal. Like other pigs, it mainly eats leaves, roots and fruits. 

One interesting fact about babirusa is, it lacks the bone in its nose, so it never digs the ground with its nose like other swine do. 

Though many people do not know about the animal, the babirusa is on the brink of extinction. Two of the three species of babirusa are listed as "vulnerable" by International Union for Conservation of Nature (IUCN), while the other one is "endangered" with a small population of 1,000 individuals. Threats include trapping and hunting, and habitat loss caused by logging and other agricultural activities.
