Stellaria solaris

Stellaria solaris is a species very diffused in tropical Indo-Pacific, on sandy or muddy bottoms at a certain depth. The elegant shell, flat, with a decidedly solar look, may reach 13 cm, even if rarely exceeds 10 cm. The foot of the animal is divided in two parts, the fore one serves for locomotion, and the rear one is destined to the operculum formation. It eats algae and detrital foraminifers and to escape from predators often disguises the shell gluing with its long proboscis small shells, bivalves fragments and other elements deemed valid it collects, in the habitat where it moves © Giuseppe Mazza
