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.
The gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Powelliphanta is a genus of large, air-breathing land snails, pulmonate gastropods in the family Rhytididae, found only in New Zealand. They are carnivorous, eating invertebrates, mostly native earthworms. Often restricted to very small areas of moist forest, they are prey to introduced mammalian predators, and many species are threatened or endangered.
Mitchell's rainforest snail is a species of large, air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Camaenidae.
Helicarion australis is a species of air-breathing pulmonate land snail or semi-slug in the family Helicarionidae. This species is endemic to Australia.
Helicarion is a genus of air-breathing land snails or semislugs, terrestrial pulmonate gastropod mollusks in the family Helicarionidae.
Attenborougharion rubicundus is a species of air-breathing semi-slug, terrestrial pulmonate gastropod molluscs in the family Helicarionidae.
Victaphanta compacta, common name the Otway black snail, is a species of carnivorous air-breathing land snail, a terrestrial pulmonate gastropod mollusks in the family Rhytididae. The Otway Black Snail Victaphanta compacta is only found in cool temperate rainforests in the Otway Ranges, Victoria, Australia. It is one of four species of the carnivorous land snails in the genus Victaphanta and is endemic to the Otway Ranges.
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.
Helicarionidae is a family of air-breathing land snails or semi-slugs, terrestrial pulmonate gastropod mollusks in the superfamily Helicarionoidea.
The molluscshell is typically a calcareous exoskeleton which encloses, supports and protects the soft parts of an animal in the phylum Mollusca, which includes snails, clams, tusk shells, and several other classes. Not all shelled molluscs live in the sea; many live on the land and in freshwater.
Paralaoma servilis is a species of very small air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Punctidae, the dot snails.
Juliidae, common name the bivalved gastropods, is a family of minute sea snails, marine gastropod mollusks or micromollusks in the superfamily Oxynooidea, an opisthobranch group.
Mysticarion is a genus of air-breathing, tree-dwelling land snails, terrestrial arboreal pulmonate gastropod molluscs in the subfamily Helicarioninae of the family Helicarionidae.
George Alan Solem, known professionally as Alan Solem, was an American malacologist, a biologist who studied mollusks.
The Mount Hyland Nature Reserve is a protected nature reserve that is located in the New England region of New South Wales, in eastern Australia. The 2,519-hectare (6,220-acre) reserve is situated approximately 35 kilometres (22 mi) west of Dorrigo.
Semi-slugs, also spelled semislugs, are land gastropods whose shells are too small for them to retract into, but not quite vestigial. The shell of some semi-slugs may not be easily visible on casual inspection, because the shell may be covered over with the mantle.
Helicarion mastersi is a species of air-breathing land snail, also referred to as a semi-slug because of its small shell. It is a terrestrial pulmonate gastropod mollusc in the family Helicarionidae.
Ubiquitarion iridis, the iridescent semi-slug is a tree-dwelling snail in the family Helicarionidae.
Opinorelia is a monotypic genus of palmleaf snails that is endemic to Australia's Lord Howe Island in the Tasman Sea.
