Why do warthogs have warts?
Well, they don’t! The wart-like protrusions from which warthogs get their name (males have four and females have two) are actually made of cartilage and grizzle and serve a very important purpose. When fighting, these “warts” guard soft, delicate body parts, like the eyes, from the tusks of other warthogs. In fact, when warthogs fight, their tusks line up almost perfectly with their opponent’s warts. This is not to say that their fights aren’t dangerous, they just aren’t worth losing an eye over.
