This species is as close as youll get to a calm crab, well on the rockyshore perhaps. Rockyshores tend to be great places for small juviniles to live, but they can get much larger, with much scarier claws out to sea. Its these larger adults which are caught to eat, hence the name edible crab. Often purple, with thick shells these crabs tend to prefer to act like pebbles if disturbed. They are also super cute in my opinion wit two little eyes close together and often blowing bubbles! See there cute faces in this video!
