The Xylodisculidae is a taxonomic family of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia. [1] [2]
Heterobranchia, the heterobranchs, is a taxonomic clade of snails and slugs, which includes marine, aquatic and terrestrial gastropod mollusks.
The clade Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia. Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells. This clade contains more than 600 species.
Philinoidea is a taxonomic superfamily of sea slugs, specifically headshield slugs, marine gastropod mollusks in the order Cephalaspidea.
Mathildidae is a family of minute sea snails, marine gastropod molluscs in the superfamily Mathildoidea of the informal group of the Lower Heterobranchia.
Rissoellidae are a family of minute sea snails, marine gastropod molluscs in the informal group Lower Heterobranchia.
Omalogyridae are a family of minute and microscopic sea snails, marine gastropod molluscs or micromolluscs in the informal group Lower Heterobranchia. Adult shells are usually smaller than 1 millimeter.
Pyramidelloidea is a superfamily of mostly very small sea snails, marine gastropod mollusks and micromollusks within the clade Panpulmonata.
Lower Heterobranchia, also known as the Allogastropoda, is a group of rather specialized, highly evolved sea slugs and sea snails, within the subclass Heterobranchia.
Nudipleura are a clade of sea snails and sea slugs, marine gastropod mollusks within the large clade Heterobranchia.
The Cladobranchia are a taxonomic clade of nudibranchs, sea slugs, marine gastropod molluscs in the clade Dexiarchia.
Mathildoidea is a superfamily of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.
Valvatoidea is a superfamily of minute freshwater and marine snails, aquatic gastropod mollusks in the informal group Lower Heterobranchia.
Runcinoidea is a taxonomic superfamily or a clade Runcinaecea of sea slugs, marine gastropod mollusks in the order Runcinida
Piseinotecidae is a taxonomic family of sea slugs, specifically aeolid nudibranchs, marine gastropod molluscs in the superfamily Aeolidioidea. Recent studies suggest that the family might need to be merged with Flabellinidae.
†Heteroneritidae is an extinct taxonomic family of sea snails, marine gastropod mollusks in the superfamilia Pyramidelloidea.
Murchisonellidae is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Murchisonelloidea.
The Cornirostridae is a taxonomic family of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.
The Hyalogyrinidae is a taxonomic family of sea snails, marine gastropod mollusks in the informal group Lower Heterobranchia.
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.
