Chlopsidae
The Chlopsidae, or false morays, are a family of marine ray-finned fishes belonging to the order Anguilliformes, the eels. The eels in this family arefound in coral reefs worldwide. As their name suggests, they somewhat resemble moray eels in appearance. However, they are smaller than true morays, ranging from in length. Taxonomy Chlopsidae was first proposed as a family in 1815 by the French polymath and naturalist Constantine Samuel Rafinesque. The 5th edition of ''Fishes of the World'' classifies Chlopsidae in the monotypic suborder Chlopsoidei within the order Anguilliformes. Genera Chlopsidae contains the following genera: * Genus '' Boehlkenchelys'' Tighe, 1992 * Genus '' Catesbya'' Böhlke & D. G. Smith, 1968 * Genus '' Chilorhinus'' Lütken, 1852 * Genus '' Chlopsis'' Rafinesque, 1810 * Genus '' Kaupichthys'' Schultz, 1943 * Genus ''Powellichthys ''Powellichthys'' is a genus of eels in the family Chlopsidae.

Charles Tate Regan
Charles Tate Regan (1 February 1878 – 12 January 1943) was a British ichthyology, ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, London, Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Taxon described by him *See :Taxa named by Charles Tate Regan Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: Taxon named in his honor *A Thorny Catfish ''Anadoras regani'' (Stein ...

Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea. Given that in biology many scientific classification, phyla, family (biology), 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 (biophysical), environment rather than on taxonomy (biology), taxonomy. A large proportion of all life, 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.

Assumption Island
Assumption Island is a small island in the Outer Islands of Seychelles north of Madagascar, southwest of the capital, Victoria. In 2018, Seychelles and India signed an agreement to build and operate a joint military facility on a portion of the island. The Seychelles National Assembly refuted the agreement after protests by the citizens. As protests continued, the Seychellois president endorsed the Assumption Island deal with India. The plan caused public protests by activists who believed that the islands should stay out of the brewing India-China regional conflict. The agreement was declared "''dead''" by the Island's opposition party. History Assumption Island was discovered by Captain Nicolas Morphey on 14 August 1756, and was named after the religious feast of the next day. In 1908, the island was leased to Mr H. Savy of Mahé, who built a coconut plantation there. The first settlement was in the northern part of the island. During a visit two years later, he realiz ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tokunoshima
, also known in English as is an island in the Amami archipelago of the southern Satsunan Islands of Kagoshima Prefecture, Japan. The island, in area, has a population of approximately 27,000. The island is divided into three administrative towns: Tokunoshima, Isen, and Amagi. The largest population center on the island is the town of Kametsu, located along the eastern shore of the island within the administrative town of Tokunoshima. Much of the island is within the borders of Amami Guntō National Park. The island is known for having the highest fertility rate in Japan (2.25 between 2018 and 2022) as well as a significant population of supercentenarians (people living significantly beyond the age of 100). Geography Tokunoshima is the second largest island in the Amami islands, after Amami Ōshima, and the 15th largest island in Japan.

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

John Fryer (entomologist)
Sir John Claud Fortescue Fryer KBE FRS FRSE (13 August 1886 – 22 November 1948) was an English entomologist. He was president of the Royal Entomological Society from 1938 to 1939 and was a fellow of the Royal Society. Life He was born at The Priory in Chatteris, Cambridgeshire, as the son of Herbert Fortescue Fryer, a farmer and amateur entomologist, and his wife Margaret Katherine Terry. He was educated at Rugby School and Gonville and Caius College, Cambridge. Like his father and his uncle, the naturalist Alfred Fryer, his main interest was in natural history. In 1908 and 1909, he spent time in the Seychelles and Aldabra Islands on a Percy Sladen Trust expedition to study the fauna and physiography.

Eels
Eels are ray-finned fish belonging to the order (biology), order Anguilliformes (), which consists of eight suborders, 20 Family (biology), families, 164 genus, genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators. The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus ''Electrophorus''), swamp eels (order Synbranchiformes), and deep-sea spiny eels (family Notacanthidae). However, these other clades, with the exception of deep-sea spiny eels, whose order Notacanthiformes is the sister clade to true eels, convergent evolution, evolved their eel-like shapes independently from the true eels. As a main rule, most eels are marine. Exceptions are the catadromous genus Anguillidae, ''Anguilla'' and the Gymnothorax polyuranodon, freshwater moray, which spend most of their life in freshwater, the Fish migration#Classification, anadromous rice-paddy eel, whi ...
