Congridae
The Congridae are the family of conger and garden eels. Congers are valuable and often large food fishes, while garden eels live in colonies, all protruding from the sea floor after the manner of plants in a garden (thus the name). The family includes over 180 species in 32 genera. The European conger, ''Conger conger'', is the largest of the family and of the Anguilliformes order that includes it; it has been recorded at up to in length and weighing . Congrids are found in tropical, subtropical and temperate seas around the world. Clear distinguishing features among congrids are few; they all lack scales, and most possess s. They feed on crustaceans and small fish, and unlike some o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Umberto D'Ancona
Umberto D’Ancona (9 May 1896 – 24 August 1964) was an Italian biologist. He attended secondary school in Fiume and later enrolled as a student in the Faculty of Natural Sciences at the University of Budapest. During World War I he interrupted his studies to fight as artillery officer, and became wounded and was decorated for military valor. From 1916 to 1920 he studied at the University of Rome under supervision of Giulio Cotronei. He graduated on a thesis on the effect of starvation on the digestive tract of the eel. He was assistant to Giovanni Batista Grassi and later succeeded Grassi as director of the Comparative Anatomy Institute of the Sapienza University of Rome. He later moved to the University of Padua where he founded the hydrobiological station in Chioggia that now bears his name. He was a member of the Accademia dei Lincei and a corresponding member of the French Academy of Sciences. His work covered marine biology and his interests ranged from physiology to hyd ...

Leptocephalus (genus)
''Leptocephalus'' is a genus that was used for species of larval eels, called leptocephali, that were thought to be new fish species, or whose adult eel species were not known. Leptocephali differ so much in appearance from their adults that the larvae and adults of eels are not easily matched, and when first discovered, leptocephali were thought to be a distinct type of fishes, but not eels. Because of this, the genus designation of ''Leptocephalus'' was used for a while for unidentified leptocephali even after it was known that these were the larvae of eels thus becoming a "wastebasket taxon", but this practice is no longer used. Examples of marine congrid larvae, found in the western Indian Ocean and the Red Sea that were named this way are listed below. Only two species (''L. bellottii'' and ''L. ophichthoides'') in two families are currently treated as having any validity, though the validity of ''L. bellottii'' is strongly in doubt. Species There are 16 families of leptocep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and therm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kamaran Islands
Kamaran Island ( ar, كمران ''Kamarān'') is the largest Yemeni island in the Red Sea. The island is long and wide and is strategically located at the southern end of the Red Sea. It is a "shelf island" located in the shallow waters of the Arabian peninsula's continental shelf with coral reefs surrounding three sides of the island. The population numbers 2,200. Kamaran is generally flat, with a few hills in the south. Its highest point is Jabal Yaman (24 meters high), situated about three kilometers from Ra's al Yaman, the southeastern cape of the island. History In 1513, Afonso de Albuquerque spent three months on the island after the abortive siege of Aden. The Portuguese stay was thoroughly unpleasant marked by a short supply of food, a small smattering of only goats and camels, alongside the outbreak of a mysterious epidemic that caused fever and blood clogging. During the second part of the 19th century, the island was occupied by the Turks who built a quarantine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yemen
Yemen (; ar, ٱلْيَمَن, al-Yaman), officially the Republic of Yemen,, ) is a country in Western Asia. It is situated on the southern end of the Arabian Peninsula, and borders Saudi Arabia to the Saudi Arabia–Yemen border, north and Oman to the Oman–Yemen border, northeast and shares maritime borders with Eritrea, Djibouti, and Somalia. Yemen is the second-largest Arabs, Arab sovereign state in the peninsula, occupying , with a coastline stretching about . Its constitutionally stated Capital city, capital, and largest city, is Sanaa. As of 2021, Yemen has an estimated population of some 30.4 million. In ancient times, Yemen was the home of the Sabaeans, a trading state that included parts of modern-day Ethiopia and Eritrea. Later in 275 AD, the Himyarite Kingdom was influenced by Judaism. Christianity arrived in the fourth century. Islam spread quickly in the seventh century and Yemenite troops were crucial in the early Islamic conquests. Several Dynasty, dynasties ...

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. It has an average depth of 490 m (1,608 ft), and in the central ''Suakin Trough'' it reaches its maximum depth of . The Red Sea also has exten ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heteroconger
''Heteroconger'' is a genus of marine congrid eels. These small, slender garden eels live in groups where each individual has its own burrow. Usually, only the head and front half of the body is visible. The greatest species richness is in the Indo-Pacific, but species are also found in the warmer parts of the Atlantic (including the Caribbean) and the eastern Pacific. Its name relates to how a huge colony of the eels looks swaying in the current. The garden eel is roughly 40 cm (16 in) long. The eel has large eyes compared to its body, and a weak sense of smell because of its tiny nostrils. It is timid around other animals and people, but slightly aggressive towards other males of its species. If it feels threatened, it retreats into its burrow and closes it with a mucus block so the predator cannot dig into its home. It has a gland in its tail that secretes a sticky substance that keeps the burrow from falling in on itself and burying the garden eel in sand. Scientis ...
