picture info	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]
	Parakysis ''Parakysis'' is a genus of catfishes (order Siluriformes) of the family Akysidae. It includes six species. Distribution ''Parakysis'' species are found in small forest streams of Sundaic Southeast Asia. ''P. anomalopteryx'' originates from the Kapuas River basin in western Borneo. ''P. grandis'' inhabits the Kapuas and Kuching River basins in Borneo and Deli, Indragiri, and Batang Hari basins in Sumatra. ''P. longirostris'' is distributed in Singapore, peninsular Malaysia, and the Riau Archipelago. ''P. verrucosus'' is known from Peninsular Malaysia and the Riau Archipelago. The discovery of ''P. notialis'' in 2003 expanded the known range of ''Parakysis'' species to the Barito River basin in southern Borneo. Description They are cryptically colored fishes that have a highly rugose skin with tubercles all over the body, branched mandibular barbels, a long, low adipose ridge, and a forked caudal fin.
