Red Sea
The Red Sea ( ar, البحر الأحمر - بحر القلزم, translit=Modern: al-Baḥr al-ʾAḥmar, Medieval: Baḥr al-Qulzum; or ; Coptic: ⲫⲓⲟⲙ ⲛ̀ϩⲁϩ ''Phiom Enhah'' or ⲫⲓⲟⲙ ⲛ̀ϣⲁⲣⲓ ''Phiom ǹšari''; Tigrinya: ቀይሕ ባሕሪ ''Qeyih Bahri''; ) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab el Mandeb strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly 438,000 km2 (169,100 mi2), is about 2250 km (1398 mi) long, and — at its widest point — 355 km (220.6 mi) wide.

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brittle Star
Brittle stars, serpent stars, or ophiuroids (; ; referring to the serpent-like arms of the brittle star) are echinoderms in the class Ophiuroidea, closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to in length on the largest specimens. The Ophiuroidea contain two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Over 2,000 species of brittle stars live today. More than 1,200 of these species are found in deep waters, greater than 200 m deep. Range The ophiuroids diverged in the Early Ordovician, about 500 million years ago. Ophiuroids can be found today in all of the major marine provinces, from the poles to the tropics. Basket stars are usually confined to the deeper parts of this range; Ophiuroids are known even from abyssal (>6,000 m) depths. However, brittle stars are also common members of reef communities, where t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Ophiocoma Echinata
''Ophiocoma echinata'', the spiny ophiocoma, is a species of brittle star belonging to the family Ophiocomidae. It is the type species of the genus ''Ophiocoma'' and is found in the tropical west Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. Description ''Ophiocoma echinata'' is a large brittle star, with a maximum armspan of . The slender, tapering arms are densely clad with short spines and are clearly demarcated from the disc. The colour is dark with pale or cream-coloured markings, but the arms never have any red markings. Distribution and habitat ''Ophiocoma echinata'' is native to the tropical west Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. It is common throughout the Caribbean at depths down to about . It occurs in seagrass meadows, on reefs and reef flats, hiding under rocks, in cracks and crevices, under coral heads, and inside sponges. Behaviour ''Ophiocoma echinata'' uses its arms to burrow in the sand and anchor itself in crevices. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ophiocoma Scolopendrina
''Ophiocoma scolopendrina'' is a species of brittle star belonging to the family Ophiocomidae. Restricted to life in the intertidal, they live in the Indo-Pacific. They can typically be found within crevices or beneath borders on intertidal reef platforms. Unlike other ''Ophiocoma'' brittle stars, they are known for their unique way of surface-film feeding, using their arms to sweep the sea surface and trap food. Regeneration of their arms are a vital component of their physiology, allowing them to efficiently surface-film feed. These stars also have the ability to reproduce throughout the year, and have been known to have symbiotic relationships with other organisms. Description ''Ophiocoma scolopendrina'', as other brittle stars, have long, thin arms emanating from a small, disk-shaped body and are about the size of an outstretched human hand. They belong to the phylum of echinoderms, which includes sea urchins Sea urchins () are spiny, globular echinoderms in the class ...

Ophiocoma Wendtii
''Ophiomastix wendtii'', also known by its common name, the red ophiocoma, and formerly as ''Ophiocoma wendtii'', is a species of brittle stars that inhabits coral reefs from Bermuda to Brazil, primarily in the Caribbean sea. club-like spines along its arms. These brittle stars have long, thin arms emanating from a small, disk-shaped body, and are about the size of an outstretched human hand. Taxonomy ''Ophiomastix wendtii'' has been referred to by a number of different proposed names. Among these proposed names is ''Ophiocoma riisei'', suggested by Christian Frederik Lütken in 1856, though the name was never commonly accepted. It was originally named ''Ophiocoma wendtii'' by J. Muller and F. H. Troschel in 1842, though in 2018, Timothy O’Hara categorized ''O. wendtii'' under the genus ''Ophiomastix'', as one of four genera previously thought to constitute ''Ophiocoma''. The ''Ophiomastix'' genus is characterized by bearing spines, twice as high as they are wide. ''O. wendt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Peter Müller
Johannes Peter Müller (14 July 1801 – 28 April 1858) was a German physiologist, comparative anatomy, comparative anatomist, ichthyology, ichthyologist, and herpetology, herpetologist, known not only for his discoveries but also for his ability to synthesize knowledge. The paramesonephric duct (Müllerian duct) was named in his honor. Life Early years and education Müller was born in Koblenz, Coblenz. He was the son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself to become a Roman Catholic Priest. During his Secondary school, college course in Koblenz, he devoted himself to the classics and made his own translations of Aristotle. At first, his intention was to become a priest. When he was eighteen, his love for natural science became dominant, and he turned to medicine, entering the University of Bonn in 1819. There he received his Doctor of Medicine, M.D. in 1822.
