Other names for crabs in this genus include "queen crab" (in Canada) and "spider crab" – they are known by different names in different areas of the world. The generic name Chionoecetes means snow (χιών, chion) inhabitant (οἰκητης, oiketes); opilio means shepherd, and C. opilio is the primary species referred to as snow crab. Marketing strategies, however, employ snow crab for anything in the genus Chionoecetes. The name "snow crab" refers to their being commonly found in cold northern oceans.
Snow crab are caught as far north as the Arctic Ocean, from Newfoundland to Greenland and north of Norway in the Atlantic Ocean, and across the Pacific Ocean, including the East Sea[disambiguation needed], the Bering Sea, the Gulf of Alaska, Norton Sound, and even as far south as California for Chionoecetes bairdi.
Seven extant species are currently recognised in the genus:
- Chionoecetes angulatus Rathbun, 1893 – triangle tanner crab
- Chionoecetes bairdi Rathbun, 1893 – tanner crab, bairdi, or inshore tanner crab
- Chionoecetes elongatus Rathbun, 1925
- Chionoecetes japonicus Rathbun, 1932 – beni-zuwai crab
- Chionoecetes opilio (Fabricius, 1788) – snow crab or opilio
- Chionoecetes pacificus Sakai, 1978
- Chionoecetes tanneri Rathbun, 1893 – grooved tanner crab
Crabs are prepared and eaten as a dish in many different ways all over the world. The legs are usually served in clusters and are steamed, boiled, or grilled. Snow crab can also be used as an ingredient in other dishes such as snow crab macaroni and cheese.
