The phylogeny of king crabs as hermit crabs who underwent secondary calcification and left their shell has been suspected since the late 1800s. [4] They are believed to have originated during the Early Miocene in shallow North Pacific waters, where most king crab genera – including all Hapalogastrinae – are distributed and where they exhibit a high amount of morphological diversity.
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.
