Snails are gastropods a word that means “stomach foot.” This refers to the way in which the snail’s foot is modified for locomotion. The foot has a muscular foot and a fleshy footpad which helps the snail move along by contracting and expanding. Snails use their foot to glide across the ground and they often leave a trail of slime behind them.

Snails are hermaphrodites meaning that they have both male and female reproductive organs. They can mate with other snails or with themselves. During mating two snails exchange sperm and each snail then fertilizes its own eggs. Snails lay their eggs in gelatinous sacs which they attach to rocks or other hard surfaces. The eggs hatch into larvae which look like small adults. The larvae eventually settle into an adult stage during which they grow their shells.
