A snail is, in loose terms, 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.

Terrestrial animals are animals that live predominantly or entirely on land, as compared with aquatic animals, which live predominantly or entirely in the water, or amphibians, which rely on a combination of aquatic and terrestrial habitats. Terrestrial invertebrates include ants, flies, crickets, grasshoppers and spiders.
The Recife broad-nosed bat, Platyrrhinus recifinus, is a species of bat from South America. It is named for the city of Recife in Brazil, where it was first recorded by Oldfield Thomas in 1901.

The Tumbling Creek cavesnail is a species of freshwater cave snail with gills and an operculum, an aquatic gastropod mollusk in the family Amnicolidae.
Gastrocopta is a genus of minute air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the family Gastrocoptidae.
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. Land snail is the common name for terrestrial gastropod mollusks that have shells. However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water.
Diplommatinidae is a family of small land snails with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea. The Cochlostomatinae Kobelt, 1902, were previously considered a subfamily of the Diplommatinidae, but are now known to be a separate family.
Unthanks Cave Natural Area Preserve is a 171-acre (69 ha) Natural Area Preserve in Lee County, Virginia. It protects the entrance to Unthanks Cave, which houses significant biological diversity and a wide variety of invertebrate life. The cave's streams drain a significant karst area south of the Powell River.
Leslie Hubricht was an American biologist and malacologist.
Freshwater snails are gastropod mollusks which 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.
Ovachlamys fulgens is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicarionidae.
Huttonella bicolor is a species of land snail in the family Streptaxidae known commonly as the two-toned gulella.
Spipipockia is a monospecific genus of land snails with an operculum, terrestrial troglobiont gastropod molluscs in the family Pomatiopsidae. Spiripockia punctata is the only species included in Spiripockia so far.
Zospeum tholussum is a cave-dwelling species of air-breathing land snails in the family Ellobiidae. It is a very small species, with a shell height of less than 2 mm (0.08 in) and a shell width of around 1 mm (0.04 in). Z. tholussum individuals are completely blind and possess translucent shells with five to six whorls. The second whorl of their shells has a characteristic dome-like shape. They are also extremely slow-moving and may depend on passive transportation through running water or larger animals for dispersal.
Rotadiscus is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Charopidae.
