Pseudomelatomidae
Pseudomelatomidae is a family of predatory sea snails, marine gastropods included in the superfamily Conoidea (previously Conacea) and part of the Neogastropoda ( Bouchet & Rocroi, 2005). In 1995 Kantor elevated the subfamily Pseudomelatominae to the status of family Pseudomelatomidae. In 2011 Bouchet, Kantor ''et al''. moved the Crassispirinae and Zonulispirinae and numerous genera of snails loosely called turrid snails (which at that point had been placed in the family Conidae) and placed them in the family Pseudomelatomidae. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. Genera Genera within the family Pseudomelatomidae include: * '' Abyssocomitas'' Sysoev & Kantor, 1986 * '' Aguilaria'' Taylor & Wells, 1994 * '' Anticomitas'' Powell, 1942 * '' Antimelatoma'' Powell, 1942 * '' Antiplanes'' Dall, 1902 * '' Benthodaphne'' Oyama, 1962 * † ...

Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=761632 on 2019-01-27 Description The length of the shell attains 21.2 mm, its diameter 8 mm. (Original description) The strong shell contains nine or ten whorls beside the smooth protoconch. The spiral sculpture consists of fine scratches on the fasciole, sharp, usually paired, grooves on the body with wider and alternately broad and narrow rounded interspaces which are subnbdulous in the line of the transverse ribs. These nodulations are higher on the posterior margin of the interstitial bands, so that with the siphonal canal pointing vertically the base of the shell looks like a tiled roof on a cupola.

Crassispira Fuscescens
''Crassispira fuscescens'' is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae. This species is similar to † ''Drillia fuscescens'' (Gray, 1843) Description The length of the shell varies between 10 mm and 25 mm. The color of the shell is deep chocolate-brown. The longitudinal ribs commence abruptly and are separated by wider interspaces, crossed by revolving raised lines, forming granules in the keel. The whorls above the periphery are smooth and slightly concave, with a raised line next the suture. The outer lip is thickened. with a sharp edge and a broad sinus.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible 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 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'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. 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 when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
