Queen conch  (Strombus gigas)

This gastropod produces a large spiral shell with spines that are thought to be for protection (3). The shell has a wide, flared lip that is a rich pink colour (4). Within the shell, the gastropod's head has two pairs of tentacles; the larger ones carry eyes whilst the smaller pair provides a sense of smell and touch. The large foot is visible at the lip of the shell (3). The large, beautiful shell has been prized by tourists in recent years, but was previously valued more for its meat (2).
