The Trochidae are a taxonomic family of very small to large sea snails. This family is commonly known as the "top snails", because in many species the shell is shaped like a toy top. Most species in the family live either in the intertidal zone or in the shallow subtidal zone, but some live in deeper water. They are usually abundant on solid, suitable substrates, like rocky shores and reefs. This family of snails consists of herbivores, grazing with their radulae on rocky surfaces, feeding on algae and vegetable detritus, and more rarely by filter-feeding.
