Marketing strategies, however, employ snow crab for any species in the genus Chionoecetes. The name "snow crab" refers to their being commonly found in cold ...
Chionoecetes opilio is a stenothermic organism, and temperature significantly affects its biology throughout its life history, from embryo to adult. Small changes in temperature (< 2 °C) can increase the duration of egg incubation for C. opilio by a full year. [1]
Snow crab are caught as far north as the Arctic Ocean, from Newfoundland to Greenland in the Atlantic Ocean, and across the Pacific Ocean, including the Sea of Japan, the Bering Sea, the Gulf of Alaska, Norton Sound, and even as far south as California for Chionoecetes bairdi. Fishing for opilio (and rarely bairdi) crab has been the focus of ...
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.
