Most modern snails [Caenogastropoda]

Description

This huge group includes many of the snails divers commonly notice on rocks, sand, and seagrass—often with spiraled shells and varied colors. Depending on the species, you might see them grazing on algae or tucked into crevices, sometimes with a quick retreat when approached.
