Polycera Faeroensis
''Polycera faeroensis'' is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Polyceridae. Distribution This nudibranch is described originally from Faeroe Islands. In the northeast Atlantic it is a common species in shallow water as far south as Portugal.Picton, B.E. & Morrow, C.C., 2010''Polycera faeroensis'' n/nowiki> Encyclopedia of Marine Life of Britain and Ireland. Description The body of this nudibranch is translucent white with yellow processes and a yellow line along the ridge of the tail. The oral veil has eight or more yellow projections. The gills and rhinophores are translucent white, tipped with yellow. Alongside the gills the pallial margin is expanded and gives rise to a pair or a series of yellow-tipped projections. Some individuals have yellow spots or lines on the body. The animal may reach 30mm in total length. It is distinguished from '' Polycera quadrilineata'' in having more than six processes on the oral veil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faroe Islands
The Faroe Islands ( ), or simply the Faroes ( fo, Føroyar ; da, Færøerne ), are a North Atlantic island group and an autonomous territory of the Kingdom of Denmark. They are located north-northwest of Scotland, and about halfway between Norway ( away) and Iceland ( away). The islands form part of the Kingdom of Denmark, along with mainland Denmark and Greenland. The islands have a total area of about with a population of 54,000 as of June 2022. The terrain is rugged, and the subpolar oceanic climate (Cfc) is windy, wet, cloudy, and cool. Temperatures for such a northerly climate are moderated by the Gulf Stream, averaging above freezing throughout the year, and hovering around in summer and 5 °C (41 °F) in winter. The northerly latitude also results in perpetual civil twilight during summer nights and very short winter days. Between 1035 and 1814, the Faroe Islands were part of the Kingdom of Norway, which was in a personal union with Denmark from 1 ...

Polyceridae
The Polyceridae are a taxonomic family of sea slugs, dorid nudibranchs, marine gastropod mollusks within the superfamily Polyceroidea. Taxonomy The family Polyceridae is classified within the clade Doridacea, itself belonging to the clade Euctenidiacea within the clade Nudipleura (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic invertebrate animals, nearly all living in sedentary colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeding. Most marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the marine bryozoans (Stenolaemata), freshwater bryozoans (Phylactolaemata), and mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. At least two genera are solitary (''Aethozooides'' and ''Monobryozoon''); the rest are colonial. The terms Polyzoa and Bryozoa were introduced in 1830 and 1831, respectively. Soon after it was named, another group of animals was discovered whose filtering mechanism looked similar, so it was included in Bryozoa until 1869, when the two groups were no ...

Polycera Quadrilineata
''Polycera quadrilineata'', is a sea slug, a species of dorid nudibranch. It is a marine gastropod mollusc in the family Polyceridae. The specific epithet ''quadrilineata'' means four-lined and refers to the four longitudinal black lines present on the original specimen. This species is sometimes called the fourline nudibranch. In 2020 a integrative molecular and morphological study showed that ''P. quadrilineata'' was a complex of two species in the NE Atlantic and one of these species was given the new name '' Polycera norvegica''. Distribution This nudibranch was described originally from Norway. In the NE Atlantic it is a common species in shallow water.Picton, B.E. & Morrow, C.C., 2010''Polycera quadrilineata'' n/nowiki> Encyclopedia of Marine Life of Britain and Ireland. It is distributed from Greenland to Norway and south along the European coasts into the Mediterranean Sea. It is found from the intertidal zone to 160 m. It has also been reported off the South African coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinophore
A rhinophore is one of a pair of chemosensory club-shaped, rod-shaped or ear-like structures which are the most prominent part of the external head anatomy in sea slugs, marine gastropod opisthobranch mollusks such as the nudibranchs, sea hares (Aplysiomorpha), and sap-sucking sea slugs (Sacoglossa). Etymology The name relates to the rhinophore's function as an organ of "smell". ''Rhino-'' means nose from Ancient Greek ῥίς ''rhis'' and from its genitive ῥινός ''rhinos''. "Phore" means "to bear" from New Latin ''-phorus'' and from Greek -phoros (φορος) "bearing", a derivative of ''phérein'' (φέρειν). Function Rhinophores are scent or taste receptors, also known as chemosensory organs situated on the dorsal surface of the head. They are primarily used for distance chemoreception and rheoreception (response to water current). The "scents" detected by rhinophores are chemicals dissolved in the sea water. The fine structure and hairs of the rhinophor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

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.
