Trochus maculatus

Family Trochidae

This snail (shell up to 8cm high) is very abundant on reefs and rocky shores, feeding on algae.

A larger and rarer relative (shell up to 15cm) T. niloticus is often collected and polished to remove the dull outer shell layer to reveal the beautiful nacreous or "mother-of-pearl" layer, and sold as curios or made into buttons.

Family Trochidae

This is common on most rocky shores, grazing on algae. In some instances, sponges and tunicates grow on the shell surface, giving it a spongy texture, often with bright colours (orange and brown). (Shell 1-2.5cm).
