Starshell astraea, Sebastes ruberrimus

The starshell astraea is an herbivorous, bottom-dwelling gastropod of the Caribbean Sea, with close relatives in warm waters around the world. They are also often seen in home aquariums. They are members of a family commonly known as turban snails because of the shape of their hard conical shells, and come in many colors and sizes up to six inches in length. Like land-dwelling snails, sea snails build their home in chambers as they grow and use it as armor against predators such as fish, sea stars, and crustaceans.
