Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Swamp Eel
The Asian swamp eel (''Monopterus albus''), also known as rice eel, ricefield eel, or rice paddy eel, is a commercially important, air-breathing species of fish in the family Synbranchidae. It occurs in East and Southeast Asia, where it is a very common foodstuff sold throughout the region. It has been introduced to two areas near the Everglades in Florida and near Atlanta in Georgia. Taxonomy The Asian swamp eel is a freshwater, eel-like fish belonging to the family Synbranchidae (swamp eels).Nelson, J.S. Fishes of the World. 3rd. New York City: John Wiley & Sons, Inc., 1994. Print. Some work indicates that the species should be split into three geographical clades or cryptic species, although these were not given nomenclatural names, as the taxonomic synonymy was too complex to sort out at the time. The populations in the Ryukyus are distinct, the populations in China and Japan belong to another clade, and the rest, the original ''M. albus'', belong to the third group. Althoug ...

Freshwater Fish Of Asia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries 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. Simply put, 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 (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Croaking Gourami
The croaking gourami (''Trichopsis vittata'') is a species of small freshwater labyrinth fish of the gourami family. They are native to still waters in Southeast Asia and are distributed worldwide via the aquarium trade. Croaking gouramis are capable of producing a "croaking" noise using their pectoral fins. General Croaking gouramis can reach an average size of about 5 centimeters, though some individuals can grow as large as 6 or 7 centimeters. Coloration is highly variable, ranging from pale brown and green to dark purple with black or red spots on the fins. 2-4 brown or black stripes or rows of spots are present on their sides. Median fins have a thin iridescent blue coloration on their edges. The iris of the eye is bright blue or purple. Females tend to be paler than males, have a slightly rounded dorsal fin and a shorter anal fin. Most croaking gouramis live for about 2 years but with proper care can live as long as 5 in an aquarium setting. They are native to stillwater ...

Threestripe Gourami
The threestripe gourami (''Trichopsis schalleri''), also known as the Mekong croaking gourami, is a species of freshwater ray-finned fish from the subfamily Macropodusinae which is part of the gourami family Osphronemidae. It is native to south-east Asia. Description The threestripe gourami normally shows one or two, almost never three, dark stripes running the length of its body but there it lacks any strip along the base of the anal fin. The elongated reare anal fin rays do not reach beyond the middle of the caudal fin which is lanceolate in shape. The dorsal, anal and caudal fin have red margins and are marked with many blue spots. Males are larger than the females and have elongated rays in the pelvic, dorsal, anal, and caudal fins. It can attain a length of with the largest males measured at . It is intermediate in size between its congeners, being smaller than the croaking gourami (''Trichopsis vittata'') and larger than the pygmy gourami (''T. pumila''). Distribution The ...

Pygmy Gourami
The pygmy gourami (''Trichopsis pumila''), also known as the sparkling gourami, is a freshwater species of gourami native to Southeast Asia. Description Pygmy gouramis can reach a length of SL. In color, they sparkle with red, green, and blue hues, and can produce an audible croaking noise using a specialised pectoral mechanism. In the right light, its eyes appear bright blue, and its arrowhead-shaped body and caudal fins reflect a rainbow of colors as it swims. Sexing is difficult, but males have red spots above the "body line" or the stripe through their body, and females spots are duller. Habitat Its native habitat is slow rivers, rice paddies, ditches and small ponds. It is most commonly found in standing not stagnant water (including waters with low oxygen levels) that has a dense cover of floating plants. The pygmy gourami can survive in these waters because of its labyrinth organ, which allows it to breathe air from the surface. Its native habitat has a pH of 6.0†...

Three Spot Gourami
The three spot gourami (''Trichopodus trichopterus''), also known as the opaline gourami, blue gourami, and gold gourami, is a species of fish native to southeastern Asia, but also introduced elsewhere. This gourami gets its name from the two spots along each side of its body in line with the eye, considered the third spot. This species is of minor commercial importance as a food fish in its native range and is also farmed. It is also popular in the aquarium trade. Name The three spot gourami gets its vernacular name from the two spots along each side of its body in line together with the eye being considered as the third spot. It is also known as "hairfin gourami" (from its specific name ''trichopterus'') or "two-spot gourami" (in Malaysia). Variety names include "opal" or "opaline gourami" (or "Cosby gourami") for varieties with a marbled pattern, "blue gourami" for the blue morph, "gold" or "golden gourami" for the yellow morph, "platinum gourami" for the white morph, and ...

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 ...
