Siphonariidae
Siphonariidae, also known as false limpets, are a taxonomic family of small to medium-sized air-breathing sea snails, marine and brackish water pulmonate gastropod molluscs. __TOC__ Shell description Empty siphonariid limpet shells can be distinguished from true limpet shells by examining the interior. In the siphonariids there is a well-marked lateral groove on the right side of the shell, and a corresponding interruption of the ring of muscle attachment scars. These markers show the positioning of the pneumostome or pulmonary orifice. Genera Genera in the family Siphonariidae include: * '' Anthosiphonaria'' Kuroda & Habe, 1971 ** '' Anthosiphonaria sirius'' * '' Aporemodon'' Robson, 1913 * ''Benhamina'' Finlay, 1927 - with the only one species '' Benhamina obliquata'' (G. B. Sowerby I, 1825) * '' Ellsiphon'' Iredale, 1940 * '' Hebesiphon'' Iredale, 1940 * '' Heterosiphonaria'' Hubendick, 1945 * '' Hubendickula'' McAlpine, 1952 * '' Kerguelenella'' Powell, 1946 - synonym: ...

Sea Snail
Sea snails are slow-moving marine (ocean), marine gastropod Mollusca, molluscs, usually with visible external shells, such as whelk or abalone. They share the Taxonomic classification, taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible Gastropod shell, shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain Neritidae, neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example, species in the genus ''Truncatella (gastropod), Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large and diverse group of animals. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide w ...

Pulmonate
Pulmonata or pulmonates is an informal group (previously an order, and before that, a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous period to the present. Pulmonates have a single atrium and kidney, and a concentrated symmetrical nervous system. The mantle cavity is on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.
