Aartsenia Martensi
''Aartsenia martensi'' is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.Rosenberg, G. (2015). Aartsenia martensi (Dall & Bartsch, 1906). In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=740009 on 2015-12-16 Description The ovoid shell is heavy and yellowish white. It measures 5.3 mm. The small whorls of the protoconch are almost completely immersed in the first of the succeeding volutions. The five whorls of the teleoconch are inflated and increase rapidly in size. They are subtabulately shouldered at the summit, marked by numerous fine lines of growth and equally abundant, loosely placed, wavy spiral striations. These lines of growth and spiral markings give the surface a finely reticulated appearance when viewed under high magnifications. The periphery and base of the body whorl are decidedly rounded and inflated, marked lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramidellidae
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs. The pyram family is distributed worldwide with more than 6,000 named species in more than 350 nominal genera and subgenera. This family of micromollusks has been little studied and the phylogenetic relationships within the family are not well worked out. There is an absence of a general consensus regarding which species belong to a specific genus or subgenus, contributing to much confusion. Schander (1999) names more than 300 supraspecific names. As there has been no serious generic revision of the genera worldwide, generic polyphyly can be expected to be rampant throughout the family. However, the family itself is deemed monophyletic. However a study in 2011 seems to indicate that this family is deeply nested within the Pulmon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known .... Anatomy Sea snails are a very large group o ...

Arctic Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude A circle of latitude or line of latitude on Earth is an abstract east–west small circle connecting all locations around Earth (ignoring elevation) at a given latitude coordinate line. Circles of latitude are often called parallels because ... as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
