The goblin shark is a very rare, deep water specimen. It is not a threat to humans, since it lives at depths that humans can only visit via submarine.
This unmistakable shark's most recognizable feature is its long, paddle-like snout. The snout's use is unknown, but some scientists believe it allows the shark to have more ampullae of Lorenzini, therefore making its sense of electroreception stronger. Goblin shark juveniles are white to pinkish light gray dorsally and white below. Adults are pink to light tan, and preserved specimens are gray. The jaw is able to protrude very far. Their skin is soft and flabby. Goblin sharks have 5 gills on each side, two dorsal fins, no fin spines, no nictitating membranes, and their mouths are behind their eyes.
