description Masked Crab Overview
The Masked Crab, also called the helmet crab, is a burrowing marine crab of the family Corystidae found in the eastern North Atlantic and nearby waters. It has unusually long antennae that fit together to form a tube extending above the sediment. The tube helps draw water to the crab while it remains buried in sandy seabeds, where it feeds on small organisms and organic matter.
