On the Antarctic Peninsula massively migrating king crabs

On the Antarctic Peninsula massively migrating king crabs that used to be held away from the cold waters. But climate change could cause a change in the whole ecosystem.

King crabs like cold sea water, but at a certain temperature, they can not take magnesium absorbed by sea water.

Therefore, up to this point they have never met in the cold waters off the coast of Antarctica. But in recent months the temperature has changed radically.

Crabs began to invade sea urchins living peacefully in the waters surrounding the Antarctic Peninsula.

Scientists are surprised, because they were

Antarctica is waiting for the invasion of hermit crabs

The seabed surrounding the Antarctic Peninsula, is threatened by the insatiable hermit crab. The attacker — a bright red deep predator — marching in step with the global warming.

Systematics highlighted this crustacean just five years ago, setting as Neolithodes yaldwyni and placing among the 120 other species of Lithodidae. Scientists call it the ecosystem engineer as crab burrows into the seabed, feeding on worms and other small animals. This activity (under certain population size) has enormous implications for the entire marine food chain.

Laura Grange of the University of Hawaii (USA) and her colleagues studied the Palmer Basin —
