Chionoecetes opilio (snow crab)

Synonyms: Cancer opilio; Chionoecetes behringianus; Chionoecetes chilensis; Peloplastus pallasi

Wikipedia Abstract

Chionoecetes opilio, also known as snow crab, is a predominantly epifaunal crustacean native to shelf depths in the northwest Atlantic Ocean and north Pacific Ocean. It is a well-known commercial species of Chionoecetes, often caught with traps or by trawling. Male C. opilio with a total length above 91 millimetres (3.6 in) long are the most commonly trapped, especially around Canada and Newfoundland. This crab genus is found across northern parts of the Atlantic and Pacific oceans. There are seven species in the genus Chionoecetes, all of which bear the name "snow crab." Chionoecetes opilio is also related to Chionoecetes tanneri, commonly known as the tanner crab, and other crab species found in the cold, northern oceans.
