Elsewhere, it is found on rocky shores and reefs. It was previously known as Astraea calcar. Features: 3-4cm in diameter. Shell thick, flattened conical shape. Calcar means 'spur' and indeed, the outer shell has a spiral of blunt bumps and spikes. The shell is usually encrusted and thus well camouflaged on the rocks.
