The goblin shark (Mitsukurina owstoni) is one of Earth’s rarest and most elusive sharks. It’s also one of the weirdest. With its distinctive, hornlike snout and protrudable jaws, the pink-skinned living fossil is the only surviving representative of a family lineage that dates back nearly 125 million years.
