Ribbed limpets are small mollusks that grow to about one inch in length. They are very difficult to distinguish due to their highly variable color patterns, but generally are gray with greenish-brown bands and a wavy margin. During low tide they remain in place and then move around and forage when the water levels again rise. Ribbed limpets are preyed upon by shore birds, crabs and sea stars. They are able to regrow chipped or broken pieces of their shell if needed.
