Goblin Shark

A goblin shark is a very intriguing species of a shark because of that one gif shown on Discovery Channel. It is a deep-sea shark that can grow up to 5 m in length and is found at depths below 100 m with a conservation status of “Least Concern.” Since goblin sharks are deep sea creatures they tend to feed mostly on the organisms dwelling in that area. In the “all of a sudden” gif below a goblin shark appears to bump into an object blindly and suddenly spews forth “another creature” still attached to the carcass of the original goblin shark. Doing some research I was able to find that this “other creature” is actually an extension of the creatures jaw. The fact that the skin around that area on the goblin shark is extremely loose allows the jaw to elongate in such a manner. Another interesting fact about the goblin shark is that its mouth is filled with ampullae of Lorenzini  (highly sensitive receptors in the skin that basically detect temperature and even other organisms by picking up electric fields produced by that organism). Creatures like this are cool to observe, but if you’re a deep sea diver you might want to bring some extra protective gear or just resort to scuba diving.
