Ever wonder why crabs wave their pincers around? They are actually using them to communicate and will even use their pincers to make drumming noises!  

More than 6,700 species of crabs have been identified. Some crabs live exclusively in the ocean[1], while others live along the shoreline, and some crabs live in freshwater instead of the saltwater environment of the ocean. Still, others live full time on land, but always near water of some type.
