"Because males develop antlers not only on the tops of their heads - but also a second row on their lower jaws that curl up and away from their heads - the zoo calls the babirusa 'the strangest looking' of the world's roughly 20 species of wild swine."
The lifespan in the wild for the babirusa is about 10 years old, and they can live up to 20 years in captivity, according to the zoo.
