How Do Crabs Move?

Answer

A crab has 8 legs used for walking and 2 claws. A crab's legs do not allow them to crawl straight forward. They can only crawl side to side. One set of 4 legs push the crab, and the other 4 pull the crab. You can find more information here: http://www.sci-ctr.edu.sg/ssc/detailed.jsp?artid=1094&type=6&root=4&parent=4&cat=35

Crabs move by legs. Their claws serve to protect them from danger and allows them to move about in the water or on land. Crabs are very tasty and will probably move away from you to keep from being eaten.
