Snails
Gastropoda
EOL Text
The Class Gastropoda includes snails and slugs. Most gastropods have a single, usually spirally coiled shell, but the shell is lost or reduced in some groups. Many snails have an operculum, a plate that closes the gastropod's opening. Shelled gastropods have mantles, while those without shells have reduced to absent mantles.
Gastropods have a muscular foot used for creeping in most species. In some, the foot is modified for swimming or burrowing. Most gastropods have a well-developed head that includes eyes at the end of one to two pairs of tentacles.

Gastropods, the only mollusks with terrestrial representatives, occur in nearly every habitat type. On land they’re found in wet and dry areas, including deserts; from low to high elevations; from tropical to polar latitudes (as high as there is humic material and leaf litter). Inland aquatic habitats range from puddles to lakes and rivers, fresh to salt water, and include sulfurous hot springs. In the ocean they occupy all habitat types, from deep ocean basins and hydrothermal vent communities to high intertidal splash zones and from warm tropical waters to cold polar seas.

Gastropods feed on very small things. Most of them scrape or brush particles from surfaces of rocks, seaweeds, animals that don't move, and other objects. For feeding, gastropods use a radula, a hard plate that has teeth.
Gastropod feeding habits are extremely varied, although most species make use of a radula in some aspect of their feeding behavior. Some graze, some browse, some feed on plankton, some are scavengers or detritivores, some are active carnivores.
