Biology & Habitat

Appearance

Alaska snow crabs have a hard rounded shell, four pairs of walking legs, and one pair of claws. On top they are brownish in color and underneath they are lighter. Their eyes are green or greenish blue. Males and females can be distinguished by the shape of their abdominal flaps. On males this flap is triangular, and on females it is broadly rounded.

Biology

Male Alaska snow crab can reach 6 inches in shell width but females seldom grow larger than 3 inches. Scientists estimate that snow crabs may live for up to 20 years. Females can carry up to nearly 100,000 eggs, depending on their size. They hatch their larvae in the spring when there is plenty of food in the water column. When the eggs hatch, the larvae look like tiny shrimp.

Where They Live

Range Alaska snow crabs are found off the coast of Alaska in the Bering, Beaufort, and Chukchi Seas. Habitat Alaska snow crabs prefer soft sandy or muddy ocean bottoms, typically in water less than 650 feet deep, where they can burrow if threatened by predators and where they can feed on the animals living in the sediment.

Commercial Fishery & Harvest

In 2024, there were no commercial landings of Alaska snow crab because the commercial fishery was closed. Gear types, habitat impacts, and bycatch: The fishing fleet is made up of a variety of vessels, from small inshore vessels to large-scale “super crabbers” that fish in the Bering Sea. Commercial fishermen use crab pots to harvest snow crab. They bait the pots with chopped herring, mackerel, or squid and lower the pots over silt and mud ocean bottoms. After a couple days, fishermen haul the pots back on board, empty them, and sort the catch – then start all over again.
