Snow crabs get their name from the color of their meat, which turns a bright, snowy white when cooked. The connection to snow goes even deeper than a common name, though. The scientific genus for these crabs, Chionoecetes (pronounced ki-no-see-tes), comes from Greek roots meaning “snow inhabitant,” combining “chio” (snow) and “ioketes” (inhabitant).
The Meat That Inspired the Name
NOAA Fisheries puts it plainly: “The snow-white meat is what gives the snow crab its name and its reputation as a delicacy.” When you crack open a cooked snow crab leg, the flesh inside is distinctly white, with a delicate, tender texture that sets it apart from the darker, more fibrous meat of some other crab species. This visual quality made the name intuitive for fishermen and consumers alike, and it stuck as the official common name in both the U.S. and Canadian markets.
A Name Built Into the Science
What’s unusual about snow crabs is that the “snow” connection wasn’t just a marketing choice. When scientists classified the genus Chionoecetes, they baked the concept of snow right into the Latin name. These crabs live in some of the coldest ocean waters on the planet, burrowing into soft, muddy bottoms in seas where ice is a seasonal reality. So the name works on two levels: the white meat and the frigid, snow-adjacent habitat.
In Alaskan waters, snow crabs are found in the Bering, Beaufort, and Chukchi Seas, typically in water less than 650 feet deep. They prefer sandy or muddy ocean floors where they can dig in to hide from predators and feed on small animals living in the sediment. These are genuinely cold-water creatures, thriving in conditions that would be inhospitable to most marine life.
Snow Crab vs. Tanner Crab
There’s a common source of confusion here. The genus Chionoecetes includes several species, but only one is officially called “snow crab” in U.S. fisheries: Chionoecetes opilio. Its close relative, Chionoecetes bairdi, is properly called Southern Tanner crab, though it’s sometimes marketed under the snow crab label. According to NOAA’s processors guide, “Snow crab is the correct common name for Chionoecetes opilio and not for C. bairdi.” Tanner crabs are larger and have a slightly different flavor profile, but the two species look similar enough that the names get swapped in restaurants and grocery stores.
The Alaska Department of Fish and Game notes that Tanner crab are “often marketed under the name snow crab,” which means that if you’ve eaten “snow crab” at a buffet, you may have actually been eating Tanner crab. True snow crab legs are thinner than Tanner crab legs and have that characteristic fine, white, sweet meat.
Where Snow Crabs Stand Today
Snow crabs made headlines in recent years after their population in the Bering Sea collapsed dramatically, leading to a closed fishing season that shocked the industry. The picture is improving, but slowly. The 2025 trawl survey showed strong increases in the abundance of mature males and females, which fisheries managers described with “great optimism.” However, large males, the ones the fishing industry prefers, remain at low levels. As a result, the directed fishery for Bering Sea snow crab remains closed for the 2025/26 season, with a total allowable catch set at zero despite a theoretical limit of nearly 13 million pounds.
The recovery is real but incomplete. Younger crabs are filling in, which is a promising sign for future seasons, but it takes time for those smaller crabs to grow into the size class that supports a commercial harvest. For now, snow crab on your plate is more likely to come from Canadian Atlantic fisheries, where a separate population supports its own quota system.
