turban snail Astraea calcar Family Turbinidae updated Mar 09 Where seen? This snail with a flattened wheel-shaped shell is sometimes seen on our offshore Southern islands, or rocky shores together with its relatives of the Family Turbinidae. 'Calcar' means 'spur' and indeed, the shell has a spiral of blunt spikes. Features: 3-4cm in diameter. Shell thick, flattened conical shape with a spiral of blunt bumps and spikes. The shell is usually encrusted and thus well camouflaged on the rocks. Shell opening is smooth and pearly. Small, chalky operculum that is hemi-spherical. |
