A diver holds two giant king crabs off the coast of Norway in the Barents Sea. The red king crab (Paralithodes camtschaticus) is an invasive species in the Barents Sea that is rapidly expanding its range to the south along the coast of Norway (by up to 40 km per year) and northwards towards Svalbard.
This crab is native to the northern Pacific Ocean, from Vancouver Island and the coast of Alaska, including the Aleutian Islands, across to the coastal waters of the Kamchatka Peninsula and Japan. The largest of the king crabs, its leg span can reach 1.8 metres and it can weigh well over 12 kilos.
