The Greenland shark, Somniosus microcephalus.




We know that the white shark can reach up to 6 meters long (18 ft) and, of course, is a large predator. But in terms of dangerous sharks, and murderers of large dams, we must speak of one that surpasses the great white shark, The Greenland shark.

This shark receives other name as the sleeper shark, gurry shark, ground shark, grey shark, or by the Inuit languages name Eqalussuaq.

This large shark of 7 meters (21 ft) long, lives at great depths to 2,500 meters (9.000 ft) , where no sunlight reaches. In the dark, the view is useless and the smell takes over. So when his refined sense of smell perceives the slightest speck of blood of any of its wounded prey, manages to capture it even found over 1 mile away.


It is true that by living most of his time in cold, dark waters, the shark has to reserve its precious energy, so their movements are slow ... as lazy. But make no mistake. The Greenland Shark up to the surface and when it finds its prey, it is less aggressive than any other shark, either the white shark, the bull shark or tiger shark. In many specimens have been caught, have been found walruses, seals and even polar bear parts. I imagine it, a polar bear, thanks to global warming has to swim across large distances between icebergs and boreal shark lurking down, biting, tiring, exhausting to death by drowning of a polar bear, already difficult to survival.


Thought to be one of the few animals that, together with the sperm whale and Pacific sleeper shark, comes to feed on giant and colossal squid.

Finally, much more can be said of this shark, but concluded by good news, we can rejoice in knowing that, for now, this enigmatic shark is not endangered.

Curiosity: The first image shows the eye "something". Now it is a very common parasite of this species.
