Cryptolithodes sitchensis, known as the umbrella crab and the turtle crab, 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. 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).
