Choristella Leptalea
''Choristella leptalea'' is a species of sea snail, a marine gastropod mollusk in the family Choristellidae. Description Distribution This marine species occurs in the Atlantic Ocean off New Jersey, USA. Description The maximum recorded shell length is 4 mm.Welch J. J. (2010). "The "Island Rule" and Deep-Sea Gastropods: Re-Examining the Evidence". '' PLoS ONE'' 5(1): e8776. doi:10.1371/journal.pone.0008776. The dull opaque white shell lacks any sculpture. It has a very delicate texture. The shell is a flattened little elevated spire. It consists of 3½ whorls with a large body whorl. The suture is very deep, somewhat channeled. The small umbilicus is round and deep. The nearly circular aperture is oblique. The simple peritreme is continuous, slightly attached to the body whorl and reflected over the umbilicus. The thin operculum is round-ovate and has a delicate horn color. The radula contains numerous rows of delicate colored, rather stout, non-serrate teeth, ...

''Choristella'' is a genus of sea snails, marine gastropod mollusks in the family Choristellidae.MolluscaBase eds. (2020). MolluscaBase. Choristella Bush, 1897. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=137780 on 2020-08-11 Description (Original description by Bush) This genus is proposed for species of small shells of few convex whorls forming a flattened, little elevated spire with a minute, scarcely raised, nuclear whorl and a large body whorl. The suture is very deep, and somewhat channeled. The umbilicus is small, round, deep, showing some of the whorls with rounded walls. The oblique aperture is nearly circular. The peristome is simple, continuous, slightly attached to the body whorl, and reflected over the umbilicus. The operculum of the type species is thin, roundly ovate. it has a delicate horn color, of few abruptly enlarging whorls indistinctly defined by a spiral thread and showing sinuous transver ...

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 opi ...

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
