Sand crabs are known by this name mainly because they spend an important part of their lives buried below the sand. As other crustaceans, they are characterized by the possession of antennae, a structure that has several important roles in their behaviour and physiology.
For instance, they are an important feature in their feeding behaviour. When a sand crab feeds, it begins by showing only its eyes and first pair of antennae.
