The Thousand Palms desert snail (Eremarionta millepalmarum) is a species of land snail in the family Helminthoglyptidae. This species is endemic to the United States.
A land snail is any of the numerous species of snail that live on land, as opposed to 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.
Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species that are restricted to a defined geographical area.
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.
The gastropods, more commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca, called Gastropoda. This class comprises snails and slugs from saltwater, from freshwater, and from the land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs.
Escargots, IPA: [ɛs.kaʁ.ɡo], are a delicacy consisting of cooked edible land snails. They are often served as an hors d'oeuvre and consumed by the French people, as well as people from Portugal, Sardinia, and Spain. They are also a typical of the cuisines of Crete, and Greece, as well as such North African countries as Algeria and Morocco. The word escargot is also sometimes applied to living examples of those species which are commonly eaten in this way. In British English, the menu item is usually referred to simply as snails.
Cornu aspersum, known by the common name garden snail, is a species of land snail. As such it is a terrestrial pulmonate gastropod mollusc in the family Helicidae, which includes some of the most commonly familiar land snails. Of all terrestrial molluscs, this species may well be the most widely known. In English texts it was classified under the name Helix aspersa for over two centuries, but the prevailing classification now places it in the genus Cornu.
Helix pomatia, common names the Roman snail, Burgundy snail, edible snail or escargot, is a species of large, edible, air-breathing land snail, a pulmonate gastropod terrestrial mollusc in the family Helicidae. It is a European species. In the English language it is called by the French name escargot when used in cooking. Although this species is highly prized as a food, it is difficult to cultivate and rarely farmed commercially.
Achatina fulica is a species of large land snail that belongs in the family Achatinidae. It is also known as the African giant snail or giant African snail or giant African land snail. It shares the common name "giant African snail" with other species of snails such as Achatina achatina and Archachatina marginata.
Sea snail is a common name for snails that normally live in salt water, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.
Cone snails, cone shells, or cones are common names for a large group of small to large-sized extremely venomous predatory sea snails, marine gastropod molluscs.
Helix lucorum is a species of large, edible, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails.
The white desert snail, scientific name Eremarionta immaculata, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helminthoglyptidae. This species is endemic to the United States.
The Morongo desert snail is a species of land snail in the family Helminthoglyptidae.
The Helminthoglyptinae are a subfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks within the family Xanthonychidae.
A love dart is a sharp, calcareous or chitinous dart which some hermaphroditic land snails and slugs create. Love darts are made in sexually mature animals only, and are used as part of the sequence of events during courtship, before actual mating takes place. Darts are quite large compared to the size of the animal: in the case of the semi-slug genus Parmarion, the length of a dart can be up to one fifth that of the semi-slug's foot.
Freshwater snails are gastropod mollusks which live in freshwater. 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 detritivors and some are filter feeders.
The Aldabra banded snail is a species of air-breathing land snail, a pulmonate gastropod mollusc in the family Cerastidae. The species lives on one atoll in the Seychelles Islands, Indian Ocean, and is easily recognizable for its purplish-blue banded shell. The species was thought to have died out because of climate change, but was rediscovered in 2014.
Terrestrial molluscs or land molluscs (mollusks) are ecological group that includes all molluscs that lives on land in contrast to freshwater and marine molluscs.
