SCIENTISTS have been stunned by the discovery of a shark that had eaten a polar bear. Part of the jaw of a young polar bear was found in the stomach of a Greenland shark in Svalbard, northern Norway.
Kit Kovacs, of the Norwegian Polar Institute, said: "We've never heard of this before.
"We don't know how it got there. We can't say whether or not the shark took a swimming young bear or ate a carcase.

I once read a novel about a fight staged by a promoter in a third world country between a Great White shark and a grizzly.
If the fight took place on land, I’d bet on the grizzly.
So that’s where the polar bears are going...
A Great White will eat anything, especially when it’s hungry. And polar bears do swim. This is probably old news to the Polar Bear and Shark communities.
What! It seems someone forgot to notify the Greenland sharks that Polar Bears are now a protected species...
The Greenland shark, Somniosus microcephalus, also known as the sleeper shark, gurry shark, ground shark, grey shark, or by the Inuit Eqalussuaq, is a large shark native to the waters of the North Atlantic Ocean around Greenland and Iceland. These sharks live further north than any other shark species. They are closely related to the Pacific sleeper shark. [1] The size of the Greenland shark is impressive; it is so large that its largest recorded specimen are comparable to (and may exceed) that of the great white shark.
Greenland sharks are deep-water sharks, living at depths up to 2,000 m (6,600 ft). Though famously sluggish when hunted (they can be dragged out of the water with one’s bare hands), they feed on agile prey such as fish, and on mammals like seals.[2] The stomachs of a few Greenland sharks have even been found to contain pieces from reindeer, horses, and even parts of a polar bear. An entire reindeer, minus its antlers, was found in the stomach contents of one Greenland shark. Greenland sharks are even cannibalistic, eating each other, because they are immune to each other’s toxic flesh.
This shark frequently has a relationship with a parasitic copepod, Ommatokoita elongata, that attaches itself to the cornea of the eye and feeds on the shark’s corneal tissue; the resulting scar tissue leads to partial blindness of the shark.[3] Also, studies show the Greenland shark could probably detect light from darkness. The copepod is a whitish-yellow creature that was said to be bioluminescent, but this was proven false by American shark parasitologist George Benz. Some theorize that the function of the copepod is to attract prey for the shark, like a fishing lure. This is suggested by the fact that these normally sluggish sharks have been found with much faster-moving animals (such as squid) in their stomachs. However, the theory of copepods acting as fishing lures is weakened by reports by Canadian wildlife biologists in Arctic Canada, where Greenland sharks have been sighted snatching caribou from the water’s edge. Biologists know little of the shark’s reproduction and life cycle, aside from ovoviviparity; its lifespan may be as long as 200 years.[4][5]
Recently, the Greenland shark has been regularly observed in the St. Lawrence Estuary, where it swims in deep and shallow water. The Greenland shark in the St. Lawrence is not completely devoid of the parasitic copepod, Ommatokoita elongata, and a number of specimens without the parasite do show signs of scarring on the cornea. In fact, the population in the St. Lawrence appears to be very visual. [6]
[edit] Greenland sharks as food
The flesh of a Greenland shark is poisonous when fresh. This is due to the presence of the toxin trimethylamine oxide, which, upon digestion, breaks down into trimethylamine, producing effects similar to extreme drunkenness. Occasionally, sled dogs that end up eating the flesh are unable to stand up due to the neurotoxins. However, it can be eaten if it is boiled in several changes of water or dried or rotted for some months (as by being buried in boreal ground, exposing it to several cycles of freezing and thawing). It is considered a delicacy in Iceland and Greenland.
Similar toxic effects occur in the related Pacific sleeper shark, but not in most other shark species, whose meat is often consumed fresh [7].
This is pretty funny. What? I am SHOCKED a shark that is a carnivore acting like one?? Amazing. These same scientists are the same ones who are POSITIVE Global Warming is Man Made. Bunch of Rocket Scientists they’ve got there.
MMMMMMM. Shark. Bear. Surf and turf special.

Note that they nab carabou from the beach.
It’s like fishing, but in reverse.
The shark flesh is poison.
Lol. Great article on Bigfoot, Barry Bonds and Giant Badgers in a steel cage match.

Anyone blame Global Warming yet? Polar Bears are now in the water being eaten by sharks because their ice is all gone?
The circle of life baffles Liberals.
Aww

The polar bear enviro nuts will be calling for a bounty on sharks.

I think it was called "Earth in the Balance" and the polar bear wins with help from the UN.
Even more dangerous than manbearpig. It's manbearsharkpig, half man, half bearshark and half pig.
I once saw one eat a rockin chair.
