Palio Dubia
''Palio dubia'' is a species of sea slug, a nudibranch, a shell-less marine gastropod mollusc in the family Polyceridae. Distribution This species was described from Norway. It has subsequently been reported from the United Kingdom north to Scandinavia, Russia and Greenland. It has also been reported from the Pacific coast of Canada.

Gulen
is a municipality in the southwestern part of Vestland county, Norway. It is part of the traditional district of Sogn. The administrative center of the municipality is the village of Eivindvik. Other villages in Gulen include Brekke, Byrknes, Dalsøyra, Dingja, Instefjord, Mjømna, Rutledal, and Ytre Oppedal. The municipality of Gulen sits to the south of the Sognefjorden and it surrounds the Gulafjorden, which is considered to be the place where Norway's west-coastal Vikings met for the Gulating, a governing body. The area along the Gulafjorden called ''Flolid'' (just east of the village of Eivindvik) is now a national historic place, where an open-air theater and annual summer play commemorates the Vikings who gathered there 1000 years ago to accept Christianity. The municipality is the 190th largest by area out of the 356 municipalities in Norway. Gulen is the 265th most populous municipality in Norway with a population of 2,230. The municipality's population density is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Sars
Michael Sars (30 August 1805 – 22 October 1869) was a Norwegian theologian and biologist. Biography Sars was born in Bergen, Norway. He studied natural history and theology at Royal Frederick University from 1823 and completed a cand.theol. degree in 1828. For several years he taught at a number of different schools, firstly in Christiania (now Oslo) and then in Bergen. In 1831 he was appointed vicar to Kinn Church on the Norwegian north-west coast; eight years later he transferred to Manger, just north of Bergen. Finally, in 1854 he was named professor of zoology at the University of Oslo (at that time Christiania) where he remained for the rest of his life. He died in 1869. He was married to Maren Welhaven, sister of the epic poet Johann Sebastian Welhaven in 1831, and had 7 daughters and 7 sons. Work Sars issued his first publication in 1829 – ' ("Contributions to the Natural History of Marine Animals"); a second followed in 1835 – ' ("Descriptions and Observations of s ...

Sea Slug
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are gastropods, i.e. they are sea snails (marine gastropod mollusks) that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of reef-dwelling species implies that these animals are under constant threat of predators, but the color can serve as a warning to other animals of the sea slug's toxic stinging cells (nematocysts) or offensive taste. Like all gastropods, they have small, razor-sharp teeth, called radulas. Most sea slugs have a pair of rhinophores—sensory te ...

Nudibranch
Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known.Ocean Portal (2017)A Collage of Nudibranch Colors Smithsonian National Museum of Natural History. Retrieved 17 April 2018. The word "nudibranch" comes from the Latin "naked" and the Ancient Greek () "gills". Nudibranchs are often casually called sea slugs, as they are a family of opistobranchs (sea slugs), within the phylum Mollusca (molluscs), but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic ''Sacoglossa'' and the colourful Aglajidae, are often confused with nudibranchs. Distribut ...

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
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.

Mollusc
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.

Taxa Named By Michael Sars
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
