The move Aliens introduced most of us to a monster that had a second smaller set of jaws open up from it’s mouth which seemed totally retarded but cool. The goblin shark pretty much has the same thing which is totally worthy of some retard attention…
The goblin shark, Mitsukurina owstoni, is a deep-sea shark, the sole living species in the family Mitsukurinidae. The most distinctive characteristic of the goblin shark is the unorthodox shape of its head. It has a long, trowel-shaped, beak-like rostrum or snout, much longer than other sharks’ snouts. Some other distinguishing characteristics of the shark are the color of its body, which is mostly pink, and its long, protrusible jaws. When the jaws are retracted, the shark resembles a pink grey nurse shark, Carcharias taurus, with an unusually long nose.
Mitsukurina owstoni is found in the deep ocean, far below where the sun’s light can reach at depths greater than 200 m. They can be found throughout the world, from Australia in the Pacific Ocean to the Gulf of Mexico in the Atlantic Ocean. They are best known from the waters around Japan, where the species was first discovered by modern science.
Goblin sharks feed on a variety of organisms that live in deep waters. Among some of their known meals are deep-sea squid, crabs and deep-sea fishes. Very little is known about the species’ life history and reproductive habits, as encounters with them have been relatively rare. As seemingly rare as they are however, there seems to be no real threat to their populations and so they are not classified as endangered species by the IUCN.
Goblin sharks can grow 11 feet (3.3 m) long and weigh 350 lb (159 kg). They have the typical shark’s semi-fusiform body. Unlike the common image of sharks, M. owstoni’s fins are not pointed and instead are low and rounded, with the anal and pelvic fins significantly larger than the dorsal fins. Their heterocercal tails are similar to the thresher shark’s, with the upper lobe significantly longer proportionately than other sharks’. In addition, the goblin shark’s tail lacks a ventral lobe.
The pink coloration, unique among sharks, is due to blood vessels underneath a semi-transparent skin (which bruises easily), thereby causing the coloring. The fins have a bluish appearance. Goblin sharks lack a nictitating membrane. They have no precaudal pit and no keels. The front teeth are long and smooth-edged, while the rear teeth are adapted for crushing.
Up to 25% of the goblin shark’s body weight can be its liver.
