The Red King Crab, also called Kamchatka or Alaskan King Crab, is one of the largest crabs and is
native to the cold seas of the north Pacific Ocean. It's body width can be nearly a foot (28 cm) and its legspan nearly 6 feet (1.8 metres).
It is a brown, reddish-brown or plum brown colour (but, like lobsters, bright red when cooked).
While it is under severe overfishing pressure in its native area (and harvested individuals typically well below the
dimensions above), it has become a thriving invasive species in the Barents Sea and North Sea (off Norway), having been introduced by the
Soviet Union, having few natural predators there and out-competing or devouring native marine life.
