Goblin Shark

The next position on the list of the weirdest deep sea fish is the Goblin shark. A rare deep-sea shark species is the goblin shark. It is the sole surviving member of the 125 million year old family Mitsukurinidae, which is sometimes referred to as a "living fossil." With an elongated, flat snout and strongly protruding jaws bearing conspicuous nail-like teeth, this pink-skinned mammal has a striking character. When mature, it is typically between 3 and 4 m long, although it can get much bigger, like the one that was reportedly taken in 2000 and measured 6 m.

Benthopelagic goblin sharks are found at depths more than 100 m throughout the world on upper continental slopes, underwater canyons, and seamounts. Adults are often found at a higher depth than juveniles. Some scientists think that these sharks might also dive for brief periods of time to depths of up to 1,300 meters.

Having said that, the creature's capacity to expand its jaw forward as it opens its mouth. Cephalopods, crabs, and teleost fish make up the majority of their food. These fish rarely interact with people. Some are used to make liver oil in Japan after being caught as bycatch. A small number of specimens were captured alive and brought to public aquariums, but they quickly perished.
