Clarias Batu
''Clarias batu'' (sometimes known under the common name Tioman walking catfish) is a species of Clariidae, clariid catfish. It is only known from Tioman Island off the eastern coast of Peninsular Malaysia. The eel-like catfish found on this island were originally identified as the widespread species ''Clarias nieuhofii'' but comparison of a large series of specimens from Tioman with a series of ''C. nieuhofii'' from the mainland revealed consistent and distinctive differences indicating a separate species. This is an elongated catfish up to 30.5 cm (12.0 inches) fish measurement, standard length. It can most readily be distinguished from ''C. nieuhofii'' by the fact that the dorsal fin, dorsal and anal fins are clearly separated from the caudal fin whereas ''C. nieuhofii'' has all these fins confluent. Care should be taken however as specimens of ''C. batu'' have been recorded which have apparently confluent fins as a result of healing after suffering damage. References ...

Tioman Island
Tioman Island ( ms, Pulau Tioman) is a mukim and an island in Rompin District, Pahang, Malaysia. It is located off the east coast of the state, and is some long and wide. It has seven villages, the largest and most populous being Kampung Tekek on the central western coast. The densely forested island is sparsely inhabited, and is surrounded by numerous coral reefs, making it a popular scuba diving, snorkelling, and surfing spot. There are many resorts and chalets for tourists around the island, which has duty-free status. In the 1970s, ''TIME Magazine'' selected Tioman as one of the world's most beautiful islands. The island is part of Pahang territory. However, it is geographically closer to mainland Johor than to mainland Pahang and is accessed via ferry service from the Johorean coastal town of Mersing. Within Tioman Island there are seven kampungs: Salang, Air Batang, Tekek, Paya, Genting, Mukut and Juara. The telephone numbers in Tioman start with 09-413, 09-41 ...

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peninsular Malaysia
Peninsular Malaysia ( ms, Semenanjung Malaysia; Jawi: سمننجڠ مليسيا), or the States of Malaya ( ms, Negeri-negeri Tanah Melayu; Jawi: نڬري-نڬري تانه ملايو), also known as West Malaysia or the Malaysian Peninsula, is the part of Malaysia that occupies the southern half of the Malay Peninsula in Southeast Asia and the nearby islands. Its area totals , which is nearly 40% of the total area of the country; the other 60% is in East Malaysia. For comparison, it is slightly larger than England (130,395 km2). It shares a land border with Thailand to the north and a maritime border with Singapore to the south. Across the Strait of Malacca to the west lies the island of Sumatra, and across the South China Sea to the east lie the Natuna Islands of Indonesia. At its southern tip, across the Strait of Johor, lies the island country of Singapore. Peninsular Malaysia accounts for the majority (roughly 81.3%) of Malaysia's population and economy; as of 2017, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarias Nieuhofii
''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] |
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] |
Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

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] |
Freshwater Fish Of Malaysia
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 is ...
