Snow crabs are a species of crab found primarily in the cold waters of the North Pacific and North Atlantic Oceans. They are known for their sweet, tender meat and are often harvested for commercial purposes. Snow crabs have long legs and a hard shell, typically featuring a light brown to reddish color. These crabs are usually caught during the winter months when they migrate to shallower waters for mating. Fisheries use traps to catch them, and they are a popular seafood choice in many restaurants. Snow crabs are also an important part of the ecosystem, serving as both predator and prey.
