Characteristicas of group: They live in shallow water they feed on worms, mussels, and slugs. They come in varieties of colors from dark blue or green to a light colored pink or white color. They have thin shells and no operculum because their bodies are too big to go into thier shell. When babies are made they attach to thier shell and then they detach themselves off the shell and onto a thick mucus thread that gets buried in the sand untill they are born.
