What do snow crabs eat?
Snow crabs are scavengers and they eat Dead fish or other animals after the other predator is done with it. They also eat algae, seaweed, and other plants
If you are shopping for snow crab and find some that have barnacles, black spots or molting on the shell. This does not affect the quality of the crab, these are called "dirty" crab (crabs that have not molted). These snow crabs are usually priced cheaper because of the appearance, but the real bonus is that they are much meatier because they have not molted. They are safe to eat.
