Pseudobagarius
''Pseudobagarius'' is a genus of catfishes ( order Siluriformes) of the family Akysidae. Taxonomy ''Pseudobagarius'' includes species that were originally part of the ''pseudobagarius'' group of the genus ''Akysis''. This group was first recognized in 1998; the authors recognized it as conceivable that this group and the ''Akysis variegatus'' represented two genera, but tentatively retained the species in a single genus. The genus was erected for these species in 2007. Distribution and habitat ''Pseudobagarius'' species are from Southeast Asia, including Borneo, Cambodia, China, Laos, Thailand, and Vietnam. ''Pseudobagarius'' species typically inhabit clear, swiftly flowing upland streams with sandy or rocky substrates. However, ''P. similis'' is known to occur in brackish water. Description ''Pseudobagarius'' species are akysids with the snout extending well anterior of the margin of lower jaw (which renders the mouth subterminal), the anterior and posterior nostrils relative ...

Akysis
''Akysis'' is the largest genus of catfishes (order (biology), order Siluriformes) of the family (biology), family Akysidae. Taxonomy In 1996, it was determined that ''Akysis'' is the cladistics, sister group to all other akysids, then only including ''Parakysis'', ''Acrochordonichthys'', and ''Breitensteinia''. However, it was acknowledged that the genus ''Akysis'' was poorly-sampled at the time and may be deemed non-monophyly, monophyletic in the future. In 1998, it was recognized that the large genus ''Akysis'' includes two species groups. The first species group was the ''Akysis variegatus'' group, for species more closely related to the biological type, type species; the other group was the ''pseudobagarius'' group for species more closely related to the formerly-named ''Akysis pseudobagarius''; the authors recognized it as conceivable that the groups represented two genera, but tentatively retained the species in a single genus. Since then, the genus ''Pseudobagarius'' was ... [...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] |
Caudal 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 ...
