Limacina is a genus of swimming predatory sea snails commonly known as sea butterflies in the family Limacinidae. This genus contains some of the world's most abundant gastropod species.
The superfamily Cavolinioidea is the most speciose group of sea butterflies. They belong to the suborder Euthecosomata.
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.
Phenacolimax is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Vitrinidae.
Melanopsidae, common name melanopsids, is a family of freshwater gastropods in the clade Sorbeoconcha. Species in this family are native to southern and eastern Europe, northern Africa, parts of the Middle East, New Zealand, and freshwater streams of some large South Pacific islands.
Omalogyra is a genus of minute marine gastropod molluscs in the family Omalogyridae.
Penion is a genus of large marine snails, commonly known as siphon whelks, classified within the mollusc family Austrosiphonidae.
Turritriton is a genus of medium-sized sea snails, marine gastropod molluscs in the family Cymatiidae. This is often still regarded merely as a subgenus of the genus Cymatium.
Cingula is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.

The Praecuvierinidae are a family of extinct, small, floating sea snails, pelagic marine opisthobranch gastropod mollusks in the superfamily Cavolinioidea.
Aerococcus is a genus in the phylum Bacillota (Bacteria). The genus was first identified in 1953 from samples of air and dust as a catalase-negative, gram-positive coccus that grew in small clusters. They were subsequently found in hospital environments and meat-curing brines. It has been difficult to identify as it resembles alpha-hemolytic Streptococcus on blood agar plates and is difficult to identify by biochemical means. Sequencing of 16S rRNA has become the gold standard for identification, but other techniques such as MALDI-TOF have also been useful for identifying both the genus and species.
Spirotropis is a genus of sea snails, marine gastropod mollusks in the family Drilliidae.
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.
Propeamussium is a genus of saltwater clams, marine bivalve mollusks in the order Ostreoida.
Conus is a genus of venomous and predatory sea snails, or cone snails, marine gastropod mollusks in the family Conidae. Prior to 2009, it included all cone snail species but is now more precisely defined, as are other cone snail genera.
Hemisurcula is an extinct genus of sea snails, marine gastropod mollusks in the family Clavatulidae.
Creseidae is a family of gastropods belonging to the order Pteropoda.
