Tritoniella Belli
''Tritoniella belli'' is a species of the nudibranch genus ''Tritoniella''. The species was described together with its synonym ''Tritoniella sinuata'' in 1907 by the British diplomat and malacologist Charles Eliot. It is found in the Southern Ocean along the coast of Antarctica and along the southern parts of the Scotia Arc The Scotia Arc is the island arc system forming the north, east and south border of the Scotia Sea. The northern border, the North Scotia Ridge, comprises (from west to east) Isla de los Estados at the tip of Tierra del Fuego, the Burdwood, Davis, ... in depths between and . Synonymy ''Tritoniella sinuata'' was synonymized by Wägele in 1989 after she found that differentiation by the characters Eliot described was impossible. She argued, that differences between specimens were caused by fixation and individual variability. References Gastropods described in 1907 Tritoniidae {{Tritoniidae-stub ...

Charles Eliot (diplomat)
Sir Charles Norton Edgcumbe Eliot (8 January 1862 – 16 March 1931) was a British diplomat, colonial administrator and botanist. He served as Commissioner of British East Africa in 1900–1904. He was British Ambassador to Japan in 1919–1925. He was also known as a malacologist and marine biologist. He described a number of sea slug species, including ''Chelidonura varians''. Career Eliot was born in the village of Sibford Gower near Banbury, Oxfordshire, England and educated at Cheltenham College and Balliol College, Oxford, where he took a double first in classical moderations and Greats, as well as winning the Craven, Ireland and Hertford scholarships. Remarkably, he also won the Boden Sanskrit Scholarship and the Houghton Syriac prize. He was a noteworthy linguist, with a full knowledge of 16 languages and conversant in 20 more. Eliot served in diplomatic posts in Russia (1885), Morocco (1892), Turkey (1893), and Washington, D.C. (1899). He also served as British Comm ...

Tritoniella
''Tritoniella'' is a genus of sea slugs, specifically dendronotid nudibranchs. It is a marine gastropod mollusc in the family Tritoniidae.The genus was described in 1907 by the British diplomat and malacologist Charles Eliot. Description ''Tritoniella'' can be differentiated from '' Tritonia'' (the only other Tritoniidae sharing its distribution range) by a wide dorsal ridge and lack of foliaceous tufts (gills). It can grow to a length of up to . Most individuals have a ridge running along the middle of the back. The colour is variable, ranging from a translucent milky white to yellow or orange. Distribution ''Tritoniella'' can be found in the Southern Ocean around the coast of Antarctica and along the Scotia Arc up north to Burdwood Bank south of the Falkland Islands at depths between and . Ecology ''Tritoniella'' feeds mainly on soft corals, but may also feed on hydroids and sea anemones. '' Tritoniella belli'' incorporates the chimyl alcohol ingested from ''Clavula ...

Malacologist
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ... and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotia Arc
The Scotia Arc is the island arc system forming the north, east and south border of the Scotia Sea. The northern border, the North Scotia Ridge, comprises (from west to east) Isla de los Estados at the tip of Tierra del Fuego, the Burdwood, Davis, and Aurora Banks; the Shag, South Georgia Island and Clerke Rocks. The eastern border comprises the volcanic South Sandwich Islands flanked by the South Sandwich Trench. The southern border, the South Scotia Ridge, (east to west) comprises Herdman, Discovery, Bruce, Pirie, and Jane Banks; the South Orkney Islands and Elephant Island. The Bransfield Strait, finally, separates the arc from the South Shetland Islands and James Ross Island flanking the tip of the Antarctic Peninsula. The Scotia Arc surrounds the small Scotia and South Sandwich Plates. The arc is formed by continental fragments that once formed a land bridge between South America and Antarctica, once part of the subduction margin that still forms the Andes. An ancestral arc ...

Gastropods Described In 1907
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.
