Pterotrachea
''Pterotrachea'' is a taxonomic genus of medium-sized to large floating sea slugs, marine pelagic gastropod molluscs in the family Pterotracheidae, which is in the infraorder Littorinimorpha. As such they are quite closely related to such families as the tritons (Ranellidae) and the tun shells (Tonnidae). These pelagic slugs are not at all closely related to the pelagic opisthobranch gastropods such as the sea angels and sea butterflies.

Pterotracheidae
Pterotracheidae is a family of medium-sized to large floating sea snails, pelagic gastropod molluscs. They are in the superfamily Pterotracheoidea along with two other similar pelagic families, the Atlantidae and the Carinariidae. These pelagic snails are not at all closely related to the pelagic heterobranch opistobranchs such as the sea angels and sea butterflies. They are in the clade Littorinimorpha, and as such they are related to such families as the tritons (Ranellidae) and the tun shells (Tonnidae), in the clade Caenogastropoda Caenogastropoda is a taxonomic clade, a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Ranellidae
The Ranellidae, common name the triton shells or tritons, are a taxonomic family of small to very large predatory sea snails, marine gastropod mollusks in the order Littorinimorpha. Subfamilies According to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, the family Ranellidae consisted of two subfamilies: *Ranellinae Gray, 1854 - synonyms: Agrobuccininae Kilias, 1973; Simpulidae Dautzenberg, 1900; Gyrineinae Higo & Goto, 1993 (n.a.) *Cymatiinae Iredale, 1913 (1854) - synonyms: Tritoniidae H.

Genera The family Ranellidae contains the following genera: * ''Haurokoa'' C. A. Fleming, 1955 † * ''Obscuranella'' Kantor & Harasewych, 2000 * ''Priene'' H. Adams & A.

Tonnidae
The Tonnidae are a family (biology), family of medium-sized to very large sea snails, known as the tun shells. These are marine invertebrates, marine gastropod molluscs in the clade Littorinimorpha. The name ''tun'' refers to the snails' shell shape, which resembles wine casks known as "tuns". While thin, the shells are also strong and lack operculum (gastropod), opercula. They are found in all tropical seas, where they inhabit sandy areas. During the day, they bury themselves in the substrate (biology), substrate, emerging at night to feed on echinoderms (especially sea cucumbers), Crustacean, crustaceans, and bivalves. Some larger species also capture fish, using their expandable probosces to swallow them whole. Females lay rows of eggs that become free-swimming larvae for several months before settling to the bottom. Taxonomy In 2005, these subfamilies were recognized in the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), taxonomy of Bouchet & Rocroi: *Cassinae Latreille ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Opisthobranchia
Opisthobranchs () is now an informal name for a large and diverse group of specialized complex gastropods which used to be united in the subclass Opisthobranchia. That taxon is no longer considered to represent a monophyletic grouping. Euopisthobranchia is a taxon containing a revised collection of opisthobranchs, and that taxon is considered monophyletic. Euopisthobranchia does not include some "traditional" opisthobranchs such as the Sacoglossa and the Acochlidiacea. The subclass Heterobranchia now contains all the species which used to be assigned to Opisthobranchia, plus all the species in the Pulmonata. The subclass Opisthobranchia included species in the order Cephalaspidea (bubble shells and headshield slugs), the sacoglossans, anaspidean sea hares, pelagic sea angels, sea butterflies, and many families of the Nudibranchia. ''Opisthobranch'' means "gills behind" (and to the right) of the heart. In contrast, ''Prosobranch'' means ''gills in front'' (of the heart). Opist ...
