Cryptolithodes sitchensis, known as the umbrella crab and the turtle crab,[3][4] is a species of king crab native to coastal regions of the northeastern regions of the Pacific Ocean, ranging from Sitka, Alaska to Point Loma, California.[5] Its carapace extends over its legs such that when it pulls in its legs, it resembles a small stone. It lives in rocky areas from the low intertidal to depths of 37 m (121 ft).[5][6]
