They can be found anywhere in the world and can be found at every part of the ocean. You can find them on the rocky shore to the deepest darkest parts of the sea. Crabs are a part of the decapod group deca means 10 legs other members of this group are lobsters,shrimp , and prawns. They all have 2 sets of claws that they use to crush or catch prey but the crabs also use them to fight and communicate to other crabs. World wide there are around 4,500 known types of crab. Crabs usually watch sideways but crabs like the spider crab can walk back and forth but that’s only because of their very large legs. Most crabs are omnivores meaning that they eat both plants and meat, because of this crabs are scavengers. The yeti crab is a very interesting and unappreciated creature.
