Breitensteinia
''Breitensteinia'' is a genus of catfishes ( order Siluriformes) of the family Akysidae. It includes three species. Taxonomy ''B. insignis'' was first described for an unusual akysid by Franz Steindachner in 1881. The genus had been monotypic since its description until a revision in 1998, along with the description of the two species ''B. cessator'' and ''B. hypselurus''. This genus stands out as derived among the akysids due to the large increase in vertebrae count. ''B. insignis'' and ''B. cessator'' are more closely related to one another than to ''B. hypselurus'', the sister group to the clade formed by the former two species.

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] |

Adipose 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 ...

Kapuas River
The Kapuas River (or Kapoeas River) is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At in length, it is the longest river in the island of Borneo and the longest river of IndonesiaMacKinnon, p. 133 and one of the world's longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta. The delta is located west-southwest of Pontianak, the capital of the West Kalimantan province.Kapuas River Encyclopædia Britannica on-line This Kapuas River should be distinguished from another , which starts on the ot ...

Barito River
The Barito River is the second longest river in Borneo after the Kapuas River with a total length of and with a drainage basin of in South Kalimantan, Indonesia. It originates in the Muller Mountain Range, from where it flows southward into the Java Sea. Its most important affluent is the Martapura River, and it passes through the city of Banjarmasin. This river is the location of the closest relative of the Malagasy language of Madagascar, the Ma'anyan language of Dayaks, from where settlers arrived in Madagascar (presumably in waves) from the 3rd to 10th century and from which the current island nation's population largely traces its origins. Geography The river flows in the southeast area of Borneo with predominantly tropical rainforest climate (designated as ''Af'' in the Köppen-Geiger climate classification). The annual average temperature in the area is . The warmest month is October, when the average temperature is around , and the coldest is January, at . The aver ...

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...
