Cryptolithodes sitchensis variously known as the umbrella crab Sitka crab or turtle crab is a species of lithodid crustacean native to coastal regions of the northeastern 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 17 m (56 ft).
