Above the Goblin shark

1. The first goblin shark was found in 1897 and in 1909. people believe that the goblin is a related to a extinct sharks called Scapanorhynchus and Anomotodon. The shark got is name by it goblin like nose and face. And the species was named by Jordan in honor of avid wildlife collector Alan Owston, who acquired the first specimen from a Japanese fisherman.

2. The Goblin shark is a deep-water shark usually found near the sea bottom, at depths of around 250 m. The deepest specimen ever caught was found at 1,300 m. There are only about 45 known specimens of Mitsukurina owstoni. Most goblin sharks that have been caught  from Japan where it was first discovered, specifically in an area between Tosa Bay and Boso Peninsula. The species’ Pacific range is rather large. M. owstoni specimens have been found in the waters off South Africa, from various sites throughout the western Pacific Ocean. Goblin sharks have also been found off the coasts of Australia and New Zealand. In the Atlantic Ocean, they have been found in the western Atlantic off French Guiana, in the eastern Atlantic in the Bay of Biscay and off Madeira and Portugal. On the other side of the Atlantic, goblin sharks have been found in the Gulf of Mexico.

3. Goblin sharks can grow to 11 feet (3.3 m) long and weigh 350 lb (159 kg). They have the typical shark’s semi-fusiform body. Unlike most 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, 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.

4. Goblin sharks hunt by sensing the presence of prey with electro-sensitive like most shark, due to the absence of light in the deep waters where it swims. Once a shark finds its prey, it suddenly protrudes its jaws, while using a tongue-like muscle to suck the victim into its sharp front teeth. Some prey they have been known to feed on include deep-sea rockfish, cephalopods and crustaceans.

5. Next to nothing is known of the goblin shark’s reproductive habits. Even though a pregnant goblin shark has never been caught or found, as members of the order Lamniformes, they are assumed to be ovoviviparous; their eggs mature and hatch inside the mother’s body and the shark gives birth to live young.
