Gastropods are found worldwide. Gastropods are by far the largest group of molluscs. Their 40,000 species comprise over 80% of living molluscs.

Gastropods are distributed throughout the ocean, and on land, essentially everywhere except the most extreme polar regions. They occur as far north as Point Barrow, Alaska (USA) at 71°23′20″N (J. Nekola, personal communication, January 17, 2011) and as far south as the sub-Antarctic islands (Solem & van Bruggen, 1984). They do not occur on the Antarctic continent.

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.
