Deep Sea Predators You Didn't Know Existed

All right, let's go. Number 10, the Goblin Shark. In 1898, the Japanese ichthyologist Kakichi Mitsukuri received a strange specimen pulled from the deep waters off Yokohama. It looked like nothing in the scientific record. A long flattened snout extending from its skull like a blade. A jaw that could detach from the rest of its face and shoot forward into open water. He sent it to American zoologist David Starr Jordan, who classified it as Mitsukurina owstoni, the only living member of a family that should have gone extinct over 100 million years ago. The creature was a survivor from the Cretaceous period, a relic that had been hunting in the lightless deep while dinosaurs walked above and continents rearranged themselves and entire oceans rose and fell.
