Goblin Sharks

 Goblin Shark Head

 

Goblin sharks are strange deep sea sharks just like the Megamouth shark. This shark has one unique characteristic that no other shark has. Its head is shaped totally different then other normal sharks with one long snout, you will clearly see this on the pictures. The skin of the goblin shark is also remarkable pink-gray. It also has a mouth full of sharp teethes that are sharp enough to bite a big peace of flesh out of someones body.

The Goblin shark, also called Mitsukurina Owstoni can be found on depths of 200 meters and more. They mostly live in temperate waters around the world like Japan, Gulf of Mexico and the Atlantic Ocean. These sharks are mainly found around Japan where many other deep sea creatures are found like the Giant Spider Crab.

The feeding behavior of this shark is just as those of other predators in its area. He feeds himself with deep sea fishes, squids and anything else that seems tasty to eat (for example Crabs)

The Goblin Shark was first described by David Starr Jordan in 1898 who caught a specimen in Japan. Some years later many other scientists have described this fish, but the encounters with this shark were so rare. At the end they named the shark after the name of the Japanese Zoologist Kakichi Mitsukuri who brought it to Jordan for a proper identification and description.

 

 Goblin Shark Aquaria

 

The Goblin Sharks live in waters of 200 meters, like I said before, but there are specimens who have been caught at greater depths of 1300 meters. In the last decencies only 45 specimens of this kinds of shark have been found or caught.  Most of these specimens have been seen around Japan, New Zealand, Australia and in some countries in Africa. These countries are known for their rare deep sea fishes and the Goblin Shark isn't an exception.

Out the 45 specimens who where caught or seen, we can conclude that these sharks can grow up to 3.3m and weigh around 160 kg. Probably there are bigger ones then this, but for now there isn't any proof of it. The tail of the Goblin Shark has a strange form and its other fins also have a strange shape. It seem like the Goblin Shark hasn't evolved for thousands of years. The Goblin Shark doesn't have a special eyelid that protects its eyes like other sharks have; When they attack a pray and what's amazing about this is that it has one huge liver! The Liver of The Goblin Shark can be about 25% of its total body weight.

The Goblin Shark hunts mostly in deep sea areas where it's very dark. Therefore they have electro sensitive organs in their snout. Almost every sharks has it and when they locate their pray they swim to it and kill it in a fraction of a second. The reproduction happens oviparous (the eggs hatch in the body of the mother and the hatch lings emerge as living young goblin sharks).

The Goblin Shark is classified as a specie of Least Concern. Humans haven't seen these animals a lot and pollution hasn't a great damage on these depths. So for now there aren't any programs to protect this specie.

"In the first century A.D., Pliny the Elder-in a bout of oceanic hubris-pronounced that there were precisely 176 species of marine fauna and that, ''by Hercules, in the ocean . . . nothing exists which is unknown for us.'' Would that we could summon Pliny from his celestial Hall of Shame and thwack him over the head with Claire Nouvian''s The Deep: The Extraordinary Creatures of the Abyss.
