The Limacinidae are a family of small sea snails, pteropods, pelagic marine gastropod mollusks in the clade Thecosomata.
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.
Celaenorrhinus is a genus of skipper butterflies which are commonly termed sprites. An alternate name is flats, for their habit of holding their wings flat when resting, but this is also used for related genera. They belong to the spread-winged skipper subfamily (Pyrginae), and therein are the type genus of tribe Celaenorrhini.
Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.
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.
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.
Hygromia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Hygromiidae, the hairy snails and their allies.
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.
Comitas is a genus of medium-sized sea snails, marine gastropod molluscs in the family Pseudomelatomidae.
Penion is a genus of large marine snails, commonly known as siphon whelks, classified within the mollusc family Buccinidae, the true whelks.
Berthelinia is a genus of gastropod belonging to the family Juliidae.
Cingula is a genus of minute sea snails, marine gastropod mollusks or micromollusks in the family Rissoidae.
Taranis is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae.
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 Firmicutes (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.
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.
