This shellfish can be found clinging to rocks in coastal areas across northern Australia. The best place to look for them is between high and low tide levels, but their camouflage and preference for crevices can make them difficult to find. A series of plates across the back of the mollusc give it the appearance of an Armadillo. A tough, roughened skirt surrounds the plated shell to further protect the animal. The creature often curls up into a ball when removed from the rocks. A sharp blow, or prising with a stout object, is often required to break its suction . . .
