The world’s oddest sharks live in Japanese oceanic trench
Living fossils and snouts like sword blades. Deep sea sharks have developed odd appearances. For unknown reasons, the deep waters around the Japanese islands are the home of sharks that are very different from their peers. A few have been known for quite a while, as they are regularly caught by line fishermen, but several of the sharks were only discovered very recently.
The most well-known example is the goblin shark, which has a large, protruding mouth and a long, pointed snout that seems almost like a sword among some individuals. The shark has never been studied in its natural habitat, so scientists do not know much about it or the purpose of the sword.
Frilled sharks are just as odd. They are very primitive sharks that look like hundred-millionyear-old fossils discovered through-out the world. Frilled sharks are not much like sharks, rather they resemble large, powerful eels. Instead of having their mouths on the lower side like other sharks, the mouths are located at the very front of the creatures.
