Megastomia is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies. [1] [2]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Sea snail common name for snails that normally live in saltwater

Sea snail is a common name for snails that normally live in salt water, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.

Family 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 being the "walnut family".

Taxonomy

Over fifty species worldwide have been placed in (sub)genus MegastomiaMonterosato, 1884 by a number of authors (e.g. Saurin, 1959, 1962; Peñas & Rolán, 1999; Giannuzzi-Savelli et al. (2014). On the basis of 16s mtDNA sequence data, Schander et al. (2003) distinguished, and placed in Megastomia, two species (M. conoidea(Brocchi, 1814) and M. corimbensis(Schander, 1994)), which clustered separately from other species placed in Odostomia Fleming, 1813. However Høisæter (2014: 34) correctly pointed out that the type species Odostomia conspicuaAlder, 1850 "is a typical Odostomia s.s. and has few traits in common with O. conoidea". Considering the large number of species involved, and considering that for most of these species Odostomia is probably not more appropriate, the published combinations with Megastomia are nevertheless retained by the database WoRMS as "accepted" until more data become available.
