Overview

Found on sandy bottoms, over off-shore reefs, frequently caught in trawling nets.
They feed on sea urchins.

Cassidae can grow very large and their shells resemble Roman Helmets. These are sand dwellers mainly hunting sea urchins such as sand dollars, using chemicals to penetrate through the hard case via the anus or by drilling a hole.
