Mastacembelidae
The Mastacembelidae are a family of fishes, known as the spiny eels. The Mastacembelids are part of the Order Synbranchiformes, the swamp eels, which are part of the Actinopterygii (ray-finned fishes). In an evaluation of the family in 2004, the subfamilies of Mastacembelidae were found to not be well supported and were rejected. Also, the genera ''Caecomastacembelus'' and ''Aethiomastacembelus'' were placed in synonymy with ''Mastacembelus''. These fish originate from Africa, and southern and eastern Asia. Spiny eels generally inhabit soft-bottomed habitats in fresh and occasionally brackish water. Some species burrow in the substrate during the day or for certain months and have been found buried in soil in drying periods. These fish have an eel-like body. The largest species can reach a maximum length of . Very characteristic of this group is the long nose appendage with two tubulated nostrils. Mastacembelids have a series of well-separated dorsal spines on their back, hence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mastacembelus
''Mastacembelus'' is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa (c. 45 species) and Asia (c. 15 species). Most are found in rivers and associated systems (even in rapids), but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species (14 endemic). A few species can even occur in brackish water. Appearance The size and pattern varies greatly depending on the exact species of ''Mastacembelus''. The smallest are '' M. latens'' and '' M. simba'', which only reach a maximum total length of . At up to , the largest of both the family and this genus is '' M. erythrotaenia''. ''M. erythrotaenia'', often known as the fire eel, is blackish with an orange-red pattern, and it is a popular aquarium fish. Otherwise species in this genus are typically brownish and often have a spotted, speckled or mottled pattern, either in another brown hue, grayish or y ...

Macrognathus
''Macrognathus'' is a genus of eel-like fish of the family Mastacembelidae of the order Synbranchiformes. These fish are distributed throughout most of South and Southeast Asia. ''Macrognathus'' species feed on small aquatic insect larvae as well as oligochaetes. Appearance and anatomy Most ''Macrognathus'' species attain in length, but a few surpass this size, with the largest being ''M. aral'' at up to . ''Macrognathus'' are mostly similar to ''Mastacembelus''. However, they differ in a more modified rostrum, which may be slightly to significantly larger and longer than those found in ''Mastacembelus''. This serves not only to find food but also to help gather food. In the aquarium A number of species of this genus are popular aquarium fish. These include the lesser spiny eel, ''Macrognathus aculeatus'', the spotfinned spiny eel, ''Macrognathus siamensis'', as well as others. Species According to FishBase, there are currently 25 recognized species in this genus. Accor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinobdella
''Sinobdella sinensis'' is an East Asian species of the spiny eel family of the order Synbranchiformes. It is the only species in the genus ''Sinobdella'' according to FishBase, but another species, '' S. dienbienensis'', is placed there by Catalog of Fishes (that species in ''Mastacembelus'' by FishBase). The placement of this genus has been debated. It is placed in Mastacembelidae as the sister group to the rest of the family. This species has been placed as a member of the family Chaudhuriidae, but the evidence for this relationship is not strong. This fish is a subtropical species found in rivers in China, Taiwan, and Vietnam Vietnam or Viet Nam ( vi, Việt Nam, ), officially the Socialist Republic of Vietnam,., group="n" is a country in Southeast Asia, at the eastern edge of mainland Southeast Asia, with an area of and population of 96 million, making i ....

Synbranchiformes
Synbranchiformes, often called swamp eels, is an order of ray-finned fishes that are eel-like but have spiny rays, indicating that they belong to the superorder Acanthopterygii. Taxonomy No synbrachiform fossil is known. The Mastacembeloidei were removed from the Perciformes and added to the Synbranchiformes after a phylogenetic analysis by Johnson and Patterson. These authors consider the Synbranchiformes to be part of a monophyletic group called Smegmamorpha, also containing Mugilimorpha, Atherinomorpha, Gasterosteiformes, and Elassomatidae. Later authors have proposed that the Synbranchiformes along with the Anabantiformes, Carangiformes, Istiophoriformes and Pleuronectiformes form a sister clade to the Ovalentaria which has been called the “Carangimorpharia” but in the 5th Edition of Fishes of the World this clade remained unnamed and unranked. There are a total of about 99 species divided over 15 genera in three families. There are two suborders: Synbranchoidei and Mast ...

Fire Eel
The fire eel (''Mastacembelus erythrotaenia'') is a relatively large species of spiny eel. This omnivorous freshwater fish is native to in Southeast Asia but is also found in the aquarium trade. Although it has declined locally (especially in Thailand) by overfishing, because of this trade it remains common overall. Description The fire eel is not a true eel, but an extremely elongated fish with a distinctive pointed snout and underslung mouth. It is part of spiny eels family, Mastacembelidae. The group gets its common name from the many small dorsal spines that precede the dorsal fin. The body is laterally compressed, particularly the rear third, where it flattens as it joins the caudal fin and forms an extended tail. The fire eel's base coloring is dark brown/grey, while the belly is generally a lighter shade of the same color. Several bright red lateral stripes and spots mark the body and vary in intensity depending on the age and condition of the individual. Usually, the mar ...

Macrognathus Siamensis
The Peacock Eel or Spotfin Spiny Eel (''Macrognathus siamensis)'' is a spiny eel found in freshwater habitats throughout Southeast Asia. They are commercially important as food and aquarium fish. Distribution The peacock eel is native to the Mekong and Chao Phraya basins, which make up the countries of Thailand, Cambodia, Laos, and Vietnam. They are mostly found in slow-moving backwaters that have a sandy or muddy bottom. There is an invasive population of peacock eels in the Everglades region of Florida, most likely being released due to the aquarium trade. The eels were first discovered in the C-111 canal in 2002, and in 2004 were also found to inhabit mangrove swamps further south. Description and ecology The peacock eels is found in slow-moving or still bodies of water such as swamps, canals, and ponds. These fish lack scales and require a soft substrate to burrow into, such as sand, mud, or silt. They breed during the wet season when adjacent forests flood. Larvae reach ...

Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...

Fishes Of The World
''Fishes of the World'' by the American ichthyologist Joseph S. Nelson (1937–2011) is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family (biology), family gets at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, while the book generally does not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not involve color illustrations. The fourth edition was the first to incorporate the wide use of DNA analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Food Fish
Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their unique metabolisms, often evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. The majority of the food energy required is supplied by the industrial food industry, which produces food with intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels, which means that the food and agricultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
