Luckily for the remaining clams, Blue Crabs also like to eat Salt Marsh Cordgrass, Eel Grass, and Sea Lettuce. So, now you know. With all those legs, it's easy to see why crabs are such good swimmers. It can easily grow a new leg to replace the other one. The eyes of the crab are on the end of stems.
Crustaceans can molt and shed their shells.
When this happens to the Blue Crab, it is no longer a hard shelled crab. It is a soft shelled crab. Females molt 18 -20 times to reach their final molt. Males molt 21 -23 times so they are larger. When molting, the shell cracks down the back, and the crab slowly backs out.
