Lithodes maja, the Norway king crab, is a species of king crab which occurs in colder North Atlantic waters off Europe and North America. It is found along the entire coast of Norway, including Svalbard, ranging south into the North Sea and Kattegat, the northern half of the British Isles (with a few records off southwest England), and around the Faroe Islands, Iceland, and off south-eastern Greenland. In the West Atlantic, it ranges from the Davis Strait between Greenland and Canada south to The Carolinas in the United States.
The whole body is brown or orange and is covered with large spikes. It lives on both soft and hard bottoms. Like most king crabs, females are asymmetrical, with the left side of the abdomen considerably larger than the right, although specimens with the reverse of this are occasionally found.
