Edmundsella Pedata
''Edmundsella pedata'' is a species of sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Flabellinidae. Description This species has a distinctive pink-purple coloration over its entire body. In the Mediterranean it can grow to about 20 mm long, while specimens in the Atlantic Ocean may grow to 50 mm. The cerata have white rings at the tip and occur in bunches which are joined together at their bases. The extremities are an opaque white in colour. Normally, the digestive gland is red. Distribution ''Edmundsella pedata'' is found as far north as Trøndelag, Norway, around the entire British Isles, and down to the Mediterranean. Although it is a common species, it is seldom found in abundance. Habitat This species occurs, often solitary or in pairs, in sublittoral areas on hard substrate such as somewhat exposed rocky surfaces. Diet This sea slug eats ''Eudendrium'' (a kind of Hydrozoa). The exact species has been unclear, but in Denmark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Montagu (naturalist)
George Montagu (1753 – 20 June 1815) was a British military officer and ornithologist. He was known for his pioneering ''Ornithological Dictionary'' of 1802, which for the first time accurately defined the status of Britain's birds. He is remembered today for species such as the Montagu's harrier, named after him. Life and work George Montagu was born to James Montagu (1713–1790), who was great-great-grandson of Lord James Montagu (d. 1665), who was younger son of Henry Montagu, 1st Earl of Manchester. Montagu is best known for his ''Ornithological Dictionary'' (1802) and his contributions to early knowledge of British birds. He showed that many previously accepted species were invalid, either because they were birds in summer or winter plumage or males and females of the same species. His study of harriers resulted in the discovery that the Montagu's harrier was breeding in southern England. He was also involved in the first British records of cirl bunting, whose breeding ...

Cerata
:''The tortrix moth genus ''Cerata'' is considered a junior synonym of ''Cydia (genus), Cydia. Cerata, singular ceras, are anatomical structures found externally in nudibranch sea slugs, especially in aeolid nudibranchs, marine animal, marine opisthobranch gastropod mollusks in the clade Aeolidida. The word ceras comes from the Ancient Greek language, Greek word "κέρας", meaning "horn", a reference to the shape of these structures. Cerata are dorsum (biology), dorsal and lateral outgrowths on the upper surfaces of the body of these nudibranchs. Function Cerata greatly extend the surface area of nudibranchs and aid in aquatic respiration, respiration, the process of gas exchange for metabolic use. Cerata are also used, in some cases, for attack and defense. In many Aeolidida, aeolid nudibranchs, the digestive system extends into the cerata. These nudibranchs eat stinging celled animals (Cnidarians) such as sea anemone, anemones, hydrozoa, hydroids and sea fans or Portuguese ...

Hydrozoa
Hydrozoa (hydrozoans; from Ancient Greek ('; "water") and ('; "animals")) is a taxonomy (biology), taxonomic class (biology), class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colony (biology), colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genus, genera within this class live in freshwater ecosystem, freshwater habitats. Hydrozoans are related to jellyfish and corals, which also belong to the phylum (biology), phylum Cnidaria.

Sublittoral
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas that are permanently submerged — known as the ''foreshore'' — and the terms are often used interchangeably. However, the geographical meaning of ''littoral zone'' extends well beyond the intertidal zone to include all neritic waters within the bounds of continental shelves. Etymology The word ''littoral'' may be used both as a noun and as an adjective. It derives from the Latin noun ''litus, litoris'', meaning "shore". (The doubled ''t'' is a late-medieval innovation, and the word is sometimes seen in the more classical-looking spelling ''litoral''.) Description The term has no single definition. What is regarded as the full extent of the littoral zone, and the way the littoral zone is divided into subreg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trøndelag
Trøndelag (; or is a county and coextensive with the Trøndelag region (also known as ''Midt-Norge'' or ''Midt-Noreg,'' "Mid-Norway") in the central part of Norway. It was created in 1687, then named Trondhjem County (); in 1804 the county was split into Nord-Trøndelag and Sør-Trøndelag by the King of Denmark-Norway. After over two centuries of separation, in 2018 they were reunited following a referendum held two years earlier. The largest city in Trøndelag is the city of Trondheim. The administrative centre is Steinkjer, while Trondheim functions as the office of the county mayor. Both cities serve the office of the county governor; however, Steinkjer houses the main functions. Trøndelag county and the neighbouring Møre og Romsdal county together form what is known as Central Norway. A person from Trøndelag is called a ''trønder''.

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mollusc
Mollusca is a phylum of protostome, protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant taxon, extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine biology, marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater mollusc, freshwater and even terrestrial molluscs, terrestrial species. The phylum is typically divided into 7 or 8 taxonomy (biology), taxonomic class (biology), classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurobiology, neurologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
