Marshallena
''Marshallena'' is a genus of sea snails, marine gastropod mollusks in the family Marshallenidae. R.S. Allen (1927) didn't specify a type species for this genus. H.J. Finlay (1927) selected ''Belophos incertus'' Marshall, 1919, which was amended by Powell (1966 + 1969) to † ''Daphnella neozelanica'' Suter, 1917 Before 2018 this genus used to belong to the family Horaiclavidae. Species Species within the genus ''Marshallena'' include: * † ''Marshallena curtata'' (Marwick, 1926) * ''Marshallena diomedea'' Powell, 1969 * † ''Marshallena neozelanica'' (Suter, 1917) * ''Marshallena nierstraszi'' (Schepman, 1913) * ''Marshallena philippinarum'' (Watson, 1882) ;Species brought into synonymy: * † ''Marshallena anomala'' Powell, 1942: synonym of † '' Zeatoma anomala'' (Powell, 1942) * † ''Marshallena austrotomoides'' Powell, 1931: synonym of † '' Zeatoma austrotomoides'' (Powell, 1931) * † ''Marshallena carinaria'' Powell, 1935: synonym of † ''Gymnobela carinaria'' ...

Marshallena Philippinarum
''Marshallena philippinarum'' is a species of sea snail, a marine gastropod mollusk in the family Marshallenidae. Description The length of the shell attains 25 mm. The thin, white shell has a fusiform shape. It shows a moderately long spire and siphonal canal. It contains about 7 whorls. The protoconch and subsequent whorls are eroded, remaining 4 whorls convex, angular, separated by a deep suture. The sculpture consists of axial ribs, rather remote on the upper whorls, 19 in number on penultimate whorl, nearly disappearing on the body whorl and numerous, raised striae or growth lines. These are crossed by spirals, of which a subsutural one is beaded, as well as those on the angle of keel ; above this latter are a few faint spirals and more numerous ones on lower part of whorls, 4 on penultimate, about 20 on the body whorl and siphonal canal, faintly beaded or crenuliferous at the points of intercrossing. The aperture is elongately oval, with a rather blunt angle abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshallena Nierstraszi
''Marshallena nierstraszi'' is a species of sea snail, a marine gastropod mollusk in the family Marshallenidae Description The length of the shell attains 25¼ mm, its diameter 12¼ mm. (Original description) The thin shell is broadly fusiform, with a rather short spire. It is light greyish-white. The protoconch is wanting. The six remaining whorls, of which the upper one is likewise eroded, are angularly convex, and slightly excavated below the deep suture. The sculpture consists of slightly oblique, narrow ribs, arcuated in the excavation, 15 in number in the penultimate whorl, with blunt tubercles about the median part of upper whorls and on the shoulder of the body whorl, with beads at their upper extremities. Just below the suture, the shell is covered with fine growth striae and spiral lirae, these lirations being faint in the excavation, stronger and crowded in lower part of whorls, more remote on the siphonal canal; the body whorl attenuated below, passing without m ...

Horaiclavidae
Horaiclavidae is a family of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. In 2011 this family was split off from the family Pseudomelatomidae (formerly the subfamily Crassispirinae McLean, 1971) by Bouchet P., Kantor Yu.I., Sysoev A. & Puillandre N. in their publication "A new operational classification of the Conoidea". It forms a clade together with the family Clavatulidae. It has many characters in common with the family Pseudomelatomidae, except the smaller shell with a low spire, the short siphonal canal and a weak or absent spiral sculpture. The radular formula is 1-0-0-0-1, but some species in this family lack a radula. Genera Genera within the family Horaiclavidae include: * '' Anacithara'' Hedley, 1922 * '' Anguloclavus'' Shuto, 1983 * '' Aoteadrillia'' Powell, 1942 * '' Asperosculptura'' Ardovini, Poppe & Tagaro, 2021 * '' Austrocarina'' Laseron, 1954 * '' Austrodrillia'' Hedley, 1918 * ''Buchema'' Corea, 1934 * '' Carinapex'' Dall, 1 ...

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
