A snail is a shelled gastropod. The name is most often applied to land snails, terrestrial pulmonate gastropod molluscs. However, the common name snail is also used for most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also numerous species of sea snails and freshwater snails. Gastropods that naturally lack a shell, or have only an internal shell, are mostly called slugs, and land snails that have only a very small shell are often called semi-slugs.
Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
The operculum is a corneous or calcareous anatomical structure like a trapdoor that exists in many groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc.
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.
The Trochidae, common name top-snails or top-shells, are a family of various sized sea snails, marine gastropod molluscs in the subclass Vetigastropoda. This family is commonly known as the top-snails because in many species the shell resembles a toy spinning top.
Crithe is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Cystiscidae. This genus is sometimes still placed within the Marginellidae.
Cancellariidae, common name the nutmeg snails or nutmeg shells, are a family of small to medium-large sea snails, marine gastropod mollusks in the clade Neogastropoda. Some of the shells of the species in this family resemble a nutmeg seed.
Vasum, common name the vase snails or vase shells, is a genus of mostly rather large predatory sea snails, marine gastropod mollusks in the subfamily Vasinae within the family Turbinellidae.
Cancellaria is a genus of medium-sized to large sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails.
Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
Xanthochorus cassidiformis is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Xanthochorus is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
Charonia lampas is a species of predatory sea snail, a marine gastropod mollusk in the family Charoniidae.
In the shell of gastropod mollusks, the lip is the free margin of the peristome or aperture of the gastropod shell.
Euclia is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, the nutmeg snails.
Euclia balboae is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails.
Conus is a genus of venomous and predatory sea snails, or cone snails, marine gastropod mollusks in the family Conidae. Prior to 2009, it included all cone snail species but is now more precisely defined, as are other cone snail genera.
Terrestrial molluscs or land molluscs (mollusks) are an ecological group that includes all molluscs that live on land in contrast to freshwater and marine molluscs. They probably first occurred in the Carboniferous, arising from freshwater ones.
Crithe cassidiformis is a species of very small sea snail, a marine gastropod mollusk or micromollusk in the family Cystiscidae.
