Above the species level close to 400 named taxa are referred to the gastropod superfamily Pyramidelloidea. Molluscs are animals belonging to the phylum Mollusca. There are around 250000 extant Species within the phylum with an estimated 70000 The class Gastropoda or the gastropods, also previously known as gasteropods, or univalves, and more commonly known as Snails Orthogastropoda is one of two major Taxonomic groupings of snails and slugs an extremely large Subclass within the huge class Gastropoda. Heterobranchia, the heterobranchs, (meaning "different-gilled snails" is a Taxonomic Superorder of sea Snails marine John Edward Gray ( 12 February 1800 &ndash 7 March 1875) was a British zoologist.

A taxon (plural taxa) or taxonomic unit, is a name designating an organism or a group of Organisms In Biological nomenclature according to Marine is an Umbrella term. As an adjective it is usually applicable to things relating to the Sea or Ocean, such as Marine biology, Marine The word snail is a Common name that can be used for almost all members of the Molluscan class Gastropoda which have coiled shells in the Pyramidelloidea has both fossil and recent members.
