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.
Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Pagurus pollicaris is a hermit crab commonly found along the Atlantic coast of North America from New Brunswick to the Gulf of Mexico. It is known by a number of common names, including gray hermit crab, flat-clawed hermit crab, flatclaw hermit crab, shield hermit crab, thumb-clawed hermit crab, broad-clawed hermit crab, and warty hermit crab.
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods.
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.
Lanistes is a genus of freshwater snails which have a gill and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails.
Coralliophilinae is a taxonomic group, a subfamily of about 200–250 sea snails, marine gastropod mollusks commonly known as the coral snails or coral shells. This is a subfamily within the very large family Muricidae, the murex or rock snails.
Freshwater snails are gastropod mollusks that 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.
Magilus antiquus, common name the Magilus coral snail, is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Leptoconchus striatus is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Magilus is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
Rubus ellipticus, commonly known as ainselu, golden evergreen raspberry, golden Himalayan raspberry, or yellow Himalayan raspberry, is an Asian species of thorny fruiting shrub in the rose family. It's native range stretches from the Indian subcontinent to southern China and Indochina and the Philippines.
Leptoconchus is a genus of medium-sized sea snails, marine gastropod mollusks in the family Muricidae, subfamily Coralliophilinae, the coral snails or coral shells.
Sinum grayi is a species of predatory sea snail, a marine gastropod mollusk in the family Naticidae, the moon snails.
Adenanthos ellipticus, commonly known as the oval-leaf adenanthos, is a flowering plant from the family Proteaceae that is endemic to Western Australia where it is considered to be Declared Rare Flora.
Elaeocarpus sylvestris, the woodland elaeocarpus, is a tree species in the genus Elaeocarpus.
Stylochidae is a family of polyclad flatworms. It includes the species Stylochus zebra, which usually lives in shells occupied by the hermit crab Pagurus pollicaris, though it can sometimes be found free living on rocks and pilings.
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.
Leptoconchus peronii is a species of sea snail, a marine gastropod mollusk, in the family Muricidae, the murex snails or rock snails.
Magilus latens is a species of sea snail, a marine gastropod mollusk, in the family Muricidae, the murex snails or rock snails.
