Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Conchology is the study of mollusc shells. Conchology is one aspect of malacology, the study of molluscs; however, malacology is the study of molluscs as whole organisms, whereas conchology is confined to the study of their shells. It includes the study of land and freshwater mollusc shells as well as seashells and extends to the study of a gastropod's operculum.
The white-lipped snail or garden banded snail, scientific name Cepaea hortensis, is a large species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae. The only other species in the genus is Cepaea nemoralis.
The periostracum is a thin, organic coating that is the outermost layer of the shell of many shelled animals, including molluscs and brachiopods. Among molluscs, it is primarily seen in snails and clams, i.e. in gastropods and bivalves, but it is also found in cephalopods such as Allonautilus scrobiculatus. The periostracum is an integral part of the shell, and it forms as the shell forms, along with the other shell layers. The periostracum is used to protect the organism from corrosion.
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.
Desmoulin's whorl snail is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc or micromollusc in the family Vertiginidae, the whorl snails.
Helix lucorum is a species of large, edible, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails.
Fruticicola fruticum is a species of medium-sized, air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Camaenidae.
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.
Carychium tridentatum is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Ellobiidae.
Mollusca is the second-largest phylum of invertebrate animals, after Arthropoda; members are known as molluscs or mollusks. Around 76,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied.
Merdigera obscura is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Enidae.
Succinella oblonga is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Succineidae.
Punctum pygmaeum is a species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Punctidae, the dot snails.
Euconulus fulvus is a species of very small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Euconulidae, the hive snails.
Lauria cylindracea, the common chrysalis snail, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Lauriidae.
Hemiplecta is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Ariophantinae of the family Ariophantidae.
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.
Chondrina arcadica is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk belonging to the family Chondrinidae. This species is also known under the synonym Chondrina arcadica clienta.
