the Goblin Shark. Described by people lucky enough to have seen one as almost "bubblegum pink", these deep sea sharks are identifiable by their extendable jaws and sharp bristling teeth. They sport a blade shaped snout that is much longer than most sharks, and very obvious when the jaws are protruding. They can reach a size of over 10 feet long and live about 200 metres deep. They live on deep sea squid, crabs and fish.
