Characteristics

Phorcus snails are characterized by their small, conical shells that are typically brightly colored and patterned. The shells have a distinctive pointed apex and a wide, rounded base. They are usually smooth or have fine, spiral ridges. The operculum, a hard, plate-like structure that closes the shell opening, is typically multispiral and horny.

These snails are herbivorous and feed on algae and diatoms. They have a distinctive radula, a ribbon-like structure with rows of teeth, that they use to scrape food off surfaces. The radula is highly specialized and adapted for their herbivorous diet.

Environment

Phorcus snails are found in a variety of habitats, including rocky shores, tide pools, and sandy bottoms. They are typically found in shallow, coastal waters and are often seen clinging to rocks, seaweeds, or other hard surfaces. They are common in temperate and subtropical regions around the world, with a particular abundance in the Mediterranean Sea.
