Jenneria pustulata

Small jewel of the sea, the Jenneria pustulata is a 15-27 mm gastropod that lives between the madrepores along the coasts of Pacific from California to Peru and Galapagos. The borders of the mantle that, if wholly expanded cover the shell, have ramified papillae with rings red, yellowish and black, having a sensory function, a little like what happens with the cowries, close relatives that, apart showy sculptures with orange studs, recall also in the shape. Hidden during the day, gets out by night to gnaw in peace the coral polyps, especially those of the genus Pocillopora © Giuseppe Mazza
