The Rarest Oinker
Mysterious, elusive, one pair of nipples, mostly-hairless.  There’s just something so touchingly familiar about the Babirusa.  Cave paintings from 35,400 years ago depict our fascination with this enigmatic pig.  The male Babirusa’s upper tusks grow vertically out of its upper jaw, like a teenage mustache.  And like a teenage mustache, these upper tusks act as a shield to protect it from other male Babirusa during their battles for island supremacy.  If these janky teeth are not ground down, eventually they can spiral back and pierce their skull. Found only on a few remote islands north of Australia, this is the rarest oinker in the world.
