Acroloxus is a genus of very small, air-breathing, freshwater snails, or more precisely limpets, aquatic pulmonate gastropods in the family Acroloxidae.
Species in the genus Acroloxus include:
Limpets are a group of aquatic snails that exhibit a conical shell shape (patelliform) and a strong, muscular foot. Although all limpets are members of the class Gastropoda, limpets are polyphyletic, meaning the various groups which are referred to as "limpets" have descended independently from different ancestral gastropods. This general category of conical shell is known as "patelliform" (dish-shaped). All members of the large and ancient marine clade Patellogastropoda are limpets. Within that clade, the members of the Patellidae family in particular are often referred to as "true limpets".
A limpet mine is a type of naval mine attached to a target by magnets. It is so named because of its superficial similarity to the limpet, a type of sea snail that clings tightly to rocks or other hard surfaces.
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.
Ancylus is a genus of very small, freshwater, air-breathing limpets. They are aquatic pulmonate gastropod mollusks in the tribe Ancylini within the family Planorbidae, the ram's horn snails and their allies.
Scutus is a genus of large sea snails or limpets with the common name "shield shells". These are marine gastropod molluscs in the family Fissurellidae, the keyhole limpets and slit limpets.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
Acroloxidae, commonly known as river limpets, are a taxonomic family of very small, freshwater snails, aquatic pulmonate gastropod limpet-like mollusks with a simple flattened conical shell in the clade Hygrophila.
Patellidae is a taxonomic family of sea snails or true limpets, marine gastropod molluscs in the clade Patellogastropoda.
Latia is a genus of very small, air-breathing freshwater snails or limpets, aquatic pulmonate gastropod molluscs in the superfamily Chilinoidea.
Gundlachia is a genus of minute freshwater snails or limpets, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies.
The river limpet is a species of very small, freshwater, air-breathing limpet, an aquatic pulmonate gastropod mollusk in the tribe Ancylini within the family Planorbidae, the ram's horn snails and their allies.
The Rocky Mountain capshell is a species of freshwater snail in the family Acroloxidae, the river limpets. It is the only member of the family found in North America.
Acroloxus lacustris, or the lake limpet, is a small freshwater limpet or snail, a species of aquatic gastropod mollusk in the family Acroloxidae.
Notocrater is a genus of deep-water true limpets, marine gastropod molluscs in the family Pseudococculinidae, one of the families of true limpets.
Freshwater snails are gastropod mollusks which 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.
Megathura crenulata is a northeastern Pacific Ocean species of limpet in the family Fissurellidae known commonly as the great keyhole limpet or giant keyhole limpet. Megathura is a monotypic genus, in other words, this is the only species in that genus. This species occurs along the rocky coast of western North America, its distribution extending from Southern California to the Baja California peninsula in Mexico. It is found in the intertidal zone and in the sea up to a depth of 33 meters.
Cosmetalepas, common name the pitted keyhole limpets, is a genus of minute deepwater keyhole limpets, marine gastropod mollusks or micromollusks in the family Fissurellidae, the keyhole limpets and slit limpets.
Scutellastra is a genus of sea snails with gills, typical true limpets, marine gastropod molluscs in the family Patellidae, the true limpets.
Acroloxus egirdirensis is a species of very small freshwater snail, which because of their shape are known as limpets, aquatic pulmonate gastropods in the family Acroloxidae.
Acroloxus pseudolacustris is a species of very small freshwater snail, which because of their shape are known as limpets, aquatic pulmonate gastropods in the family Acroloxidae.
