Slender Walking Catfish
''Clarias nieuhofii'', the slender walking catfish, is a species of clariid catfish. It has a wide distribution in Southeast Asia including southern Vietnam, Cambodia, Thailand, Malay Peninsula, parts of the Greater Sunda Islands ( Indonesia and Malaysia, including Borneo), and the Philippines. Named in honor of Johan Nieuhof (1618-1672), Dutch East India Company, who described and illustrated this species in 1682 (but later examination of Nieuhof’s illustration reveals it is a different species). This species can be distinguished from other ''Clarias'' catfishes, apart from the recently discovered ''Clarias batu'' and '' Clarias nigricans'', by the greatly elongated body which gives it a remarkably eel-like appearance. The colour is generally grey with two rows of white spots running along the length of the body just below the lateral line and 13 or 14 vertical rows of white spots just above the line. Specimens of up to 50 cm (19.7 inches) standard length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalimantan
Kalimantan () is the Indonesian portion of the island of Borneo. It constitutes 73% of the island's area. The non-Indonesian parts of Borneo are Brunei and East Malaysia. In Indonesia, "Kalimantan" refers to the whole island of Borneo. In 2019, President of Indonesia Joko Widodo proposed that Capital of Indonesia, Indonesia's capital be moved to Kalimantan, and in January 2022 Indonesian legislature approved the proposal. The shift is expected to take up to 10 years. Etymology The name ''Kalimantan'' is derived from the Sanskrit word ''Kalamanthana'', which means "burning weather island", or island with a very hot temperature, referring to its hot and humid tropical climate. It consists of the two words ''Kāla (time), kal[a]'' ("time, season, period") and ''manthan[a]'' ("boiling, churning, burning"). The indigenous people of the eastern region of Borneo referred to their island as ''Pulu K'lemantan'' or "Kalimantan" when the sixteenth century Portuguese explorer Jorge de Meneze ...

Johan Nieuhof
Johan Nieuhof (22 July 1618 in Uelsen – 8 October 1672 in Madagascar) was a Dutch traveler who wrote about his journeys to Brazil, China and India. The most famous of these was a trip of from Canton to Peking in 1655-1657, which enabled him to become an authoritative Western writer on China. He wrote An embassy from the East-India Company containing the written account of this journey. Biography Johan Nieuhof was born in Uelsen, a town in the county of Bentheim, Lower Saxony, sitting just across the Dutch-German border. His father (originally from Zwolle) was mayor of the town, and was later succeeded by one of Johan's brothers and brother-in-law. By the grace of Cornelis Jan Witsen, a leading figure within the Dutch West India Company (or "WIC"), Nieuhof left for Dutch Brazil in 1640 as a reserve officer-candidate. From then on, barring two short family visits in 1658 and 1671, he spent all the rest of his life abroad. Nieuhof was employed in Brazil to explore the regi ...

Fish Of Vietnam
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Freshwater Fish Of The Philippines
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 s ...

Clarias
''Clarias'' is a genus of catfishes ( order Siluriformes) of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek ''chlaros'', which means lively, in reference to the ability of the fish to live for a long time out of water. Taxonomy ''Clarias'' has been found to be paraphyletic. A species of '' Heterobranchus'' (''H. longifilis'') clusters deeply inside the ''Clarias'' group. Distribution They are found in inland waters throughout much of the Old World, and are one of the most widespread catfish genera in the world. The genus is found in Southeast Asia and East Asia westwards through India and the Asia Minor to Africa. The diversity of these catfishes is highest in Africa. Some (notably the walking catfish) have become pest species where they have been accidentally introduced, and particularly in Cuba, where their introduction was intentional. Description ''Clarias'' species are recognized by their long-based dorsal and anal fins, which give them ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked.
