Léon Vaillant
Léon Louis Vaillant (; 11 November 1834 – 24 November 1914) was a French zoology, zoologist. He is most famous for his work in the areas of herpetology, malacology, and ichthyology. In 1854 he graduated from the Arras College, College d'Arras, followed by studies in medicine and zoology in Paris. In 1861, he received his medical doctorate, then continued his zoological studies with Henri Milne-Edwards (1800–1885), earning his degree in natural sciences in 1865. In 1875, he became a professor at the Muséum national d'histoire naturelle, Museum of Natural History in Paris. He held a special interest involving the systematics and anatomy of turtles and crocodiles, but also made significant contributions in his investigations of reptilian physiology and behavior. Of his 200-plus scientific writings, 90 of them are based on herpetology, herpetological subjects. He participated in French naval expeditions on the ''Travailleur'' in 1880, 1881 and 1882 and on the ''Talisman'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus. In the Southern United States, catfish species may be known by a variety of slang names, such as "mud cat", " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akysidae
The stream catfishes comprise the family Akysidae of catfishes. Distribution and habitat Akysids are known from across a large area in Southeast Asia. They are found in fresh water. Fish of the subfamily Parakysinae are primarily found in the Malay Peninsula, Sumatra, Sarawak, and western and southern Borneo. Most species are generally found in deeper parts of relatively swift rivers and forest streams. Taxonomy It includes at least 57 species in five genera; many species are only recently described. The family is divided into two subfamilies, Akysinae and Parakysinae. The Parakysinae had previously been listed as an independent family. This family is sister to a clade formed by Sisoridae, Erethistidae, and Aspredinidae. Description Akysids are small to minute fishes with cryptic colouration, tiny eyes, and completely covered with unculiferous plaques or tubercles. In some genera, some of the tubercles on the body are enlarged and arranged in distinctive longitudinal rows, the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo () is the List of islands by area, third-largest island in the world, with an area of , and population of 23,053,723 (2020 national censuses). Situated at the geographic centre of Maritime Southeast Asia, it is one of the Greater Sunda Islands, located north of Java Island, Java, west of Sulawesi, and east of Sumatra. The island is crossed by the equator, which divides it roughly in half. The list of divided islands, island is politically divided among three states. The sovereign state of Brunei in the north makes up 1% of the territory. Approximately 73% of Borneo is Indonesian territory, and in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. Etymology When the sixteenth-century Portuguese explorer Jorge de Menezes made contact with the indigenous people of Borneo, they referred to their island as ''Pulu K'lemantang'', which ...

Acrochordonichthys
''Acrochordonichthys'' is a genus of catfishes ( order Siluriformes) of the family Akysidae. It includes ten species. Distribution and habitat ''Acrochordonichthys'' species are generally found at the bottoms of rivers throughout Southeast Asia. Many of the species are only known from Borneo. ''A. guttatus'' is known only from the Barito River drainage in southern Borneo. ''A. mahakamensis'' is known only from the Mahakam River drainage in eastern Borneo it is named for. ''A. chamaeleon'' and ''A. strigosus'' are known only from the Kapuas River drainage in western Borneo. ''A. falcifer'' is known only from the Kinabatangan and Segama River drainages, and possibly from the Kayan River drainage, in north-eastern Borneo. ''A. pachyderma'' is known only from the Kapuas, Mahakam, and Kinabatangan River drainages in western, eastern, and north-eastern Borneo, respectively.

Freshwater Fish Of Indonesia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Borneo
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
