Juvenile snow crabs mature in cold-water pools on the ocean floor that are sustained by melting sea ice. If waters warm above the 2 °C maximum necessary for juvenile development, their normal nursery habitat will be reduced significantly. Adults are similarly unlikely to tolerate conditions of more than 5 °C. [7]
Chionoecetes bairdi is a species of snow crab, alternatively known as bairdi crab and tanner crab. C. bairdi is closely related to Chionoecetes opilio, and it can be difficult to distinguish C. opilio from C. bairdi.
