Today students learned about gastropods. Gastropod means "stomach foot" and includes all snails and anything else that makes one shell. Gastropods have one foot, one shell, and one siphon.
Some shells are spiral and have an operculum to act as a door for when they hide inside.
Other shells are not spiral and the snail has good suction power so that predators have a difficult time pulling the snail off the rocks.
Students separated shells into bivalves and gastropods. They also practiced identifying shells and sorting them based on other characteristics.
