Gastropods, commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda.
Rostanga is a genus of sea slugs in the family Discodorididae. Some sources, such as The Sea Slug Forum still classify Rostanga in the family Dorididae.
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs.
Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.
Neritidae, common name the nerites, is a taxonomic family of small to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum. The family Neritidae includes marine genera such as Nerita, marine and freshwater genera such as Neritina, and freshwater and brackish water genera such as Theodoxus.
Cystiscidae is a taxonomic family of minute sea snails, marine gastropod mollusks or micromollusks.
Hipponix, common name hoof snails or hoof shells, is a genus of small sea snails with limpet-like shells, marine gastropod molluscs in the family Hipponicidae, the hoof snails. Many of the species in this genus have white shells.
Cystiscinae are a taxonomic subfamily of minute sea snails. These are marine gastropod mollusks or micromollusks in the family Cystiscidae, and the clade Neogastropoda.
Dendropoma is a genus of irregularly coiled sea snails known as "worm shells" or "worm snails". These are marine gastropod molluscs in the family Vermetidae, the worm snails.
Homalopoma, common name the dwarf turbans, is a genus of mostly very small sea snails with a calcareous operculum, marine gastropoda molluscs in the subfamily Colloniinae of the family Colloniidae.
Solariellidae is a family of small sea snails, marine gastropod mollusks in the superfamily Trochoidea.
Odostomia is the most speciose genus of minute sea snails, pyramidellid gastropod mollusks. This genus is placed in the family Pyramidellidae in the subfamily Odostomiinae. There are several hundred species in this diverse genus
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks. Around 76,000 extant species of molluscs are recognized, making it the second-largest metazoan phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied.
Monoplex parthenopeus, common name the giant triton or giant hairy triton, is a species of sea snail, a marine gastropod mollusk in the family Cymatiidae. It preys on other molluscs.
The Doridina, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi (2005) rejected the name Anthobranchia on the grounds that it also included Onchidium at the time of original publication. Doridina is equivalent and used in the latest classification.
Canalispira is a genus of very small sea snails, marine gastropod mollusks or micromollusks in the family Cystiscidae.
Turridae is a taxonomic family name for a number of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea.
After excluding groups not related, the informal group Sigmurethra has become the suborder Helicina, with the following infraorders and a collection of families with no superfamily:
Osvaldoginella hoffi is a species of sea snail, a marine gastropod mollusk, in the family Cystiscidae.
Osvaldoginella alejandrae is a species of sea snail, a marine gastropod mollusk, in the family Cystiscidae.
