The gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Terrestrial animals are animals that live predominantly or entirely on land, as compared with aquatic animals, which live predominantly or entirely in the water, and amphibians, which rely on aquatic and terrestrial habitats. Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water.
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.
Zonitidae, common name the true glass snails, are a family of mostly rather small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Zonitoidea.
Oxychilus draparnaudi, or Draparnaud's glass snail, is a species of small land snail, a terrestrial pulmonate gastropod mollusc in the family Oxychilidae, the glass snails.
Advena campbelli, also known as the Campbell's keeled glass-snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicarionidae. This species is endemic to Norfolk Island. It was listed as extinct by the International Union for Conservation of Nature in 1996. However, the Australian Government lists the species as Critically Endangered, and stated in 2009 that the species' IUCN status was "incorrect and requires updating." A small living population was found in 2020.
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.
Haplotrematidae is a taxonomic family of predatory air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Haplotrematoidea.
Discus rotundatus, common name rotund disc, is a species of small, air-breathing, land snail, a terrestrial pulmonate gastropod mollusk in the family Discidae, the disk snails.
Vallonia gracilicosta, common name the multirib vallonia or multiribbed vallonia, is a species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.
Allogona townsendiana, common name the Oregon forestsnail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Polygyridae.
Carychium tridentatum is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Ellobiidae.
Aegopinella nitidula is a species of small land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae, the glass snails.
Aegopinella nitens is a species of small land snail, a terrestrial pulmonate gastropod mollusk in the family Gastrodontidae, the glass snails.
Vallonia pulchella, common name the lovely vallonia, is a species of very small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.
Vallonia excentrica, common name the eccentric vallonia, is a species of very small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.
Lauria cylindracea, common name "the common chrysalis snail", is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Lauriidae.
Vallonia cyclophorella, common name the silky vallonia, is a species of very small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Valloniidae.
Nesovitrea is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Oxychilidae, the glass snails.
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.
