Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthrop ...

Terapontidae
Grunters or tigerperches are ray-finned fishes in the family Terapontidae (also spelled Teraponidae, Theraponidae or Therapontidae). This family is part of the superfamily Percoidea of the order Perciformes. Characteristics The Terapontidae is a large family of small to medium-sized perciform fishes which occur in marine, brackish and fresh waters in the Indo-Pacific region. They are characterised by a single long-based dorsal fin which has a notch marking the boundary between the spiny and soft-rayed portions. They have small to moderate-sized scales, a continuous lateral line reaching the caudal fin, and most species lack teeth on the roof of the mouth. The marine species are found in inshore sea and brackish waters, some species are able to enter extremely saline and fresh waters. In Australia and New Guinea there are a number of species restricted to fresh water. Classification The following genera are classified within the family Terpontidae: * '' Amniataba'' Whitley, 19 ...

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gibb River
The Gibb River is a river in the Kimberley region of northern Western Australia. The headwaters of the river rise between the Caroline and Gibb Ranges. The river flows in a northerly direction until merging with the Drysdale River, of which it is a tributary. Gibb River has three tributaries: North Creek, Plain Creek and Russ Creek. The Gibb River was named in 1901 by the surveyor Charles Crossland during an expedition in the Kimberley area. It is named after geologist Andrew Gibb Maitland, who had accompanied Crossland and was present during the first recorded sighting of the river. In turn, it gives its name to the Gibb River Road, a former cattle route that stretches almost 660 kilometres (410 mi) across the Kimberley between the towns of Derby and the Kununurra and Wyndham junction of the Great Northern Highway. The traditional owners of the area that the river flows through are the Ngarinjin The Ngarinyin or Ngarinjin are an Aboriginal Australian people of the ...

Drysdale River
Drysdale River is a river in the Kimberley region of Western Australia. The river rises in the Caroline Ranges, flows in a northerly direction and discharges into Napier Broome Bay near Kalumburu. The river contains several permanent pools, some of which have several examples of Indigenous Australian art known as Bradshaw paintings that can be found along the cliff faces. Notable waterfalls on the river are the Eagle Falls, which are regularly visited by Kimberley coastal cruise ships, Solea Falls north of the Johnston Creek fork, and Bango Falls on the tributary Bango Creek. There are 19 tributaries of the Drysdale, including Gibb River, Woodhouse River, Barton River, Tadarida Creek, Wax Creek, Curlew Creek, King David Creek, Ubach Creek and Damper Creek. 15% of the river's catchment area lies within Drysdale River National Park. The river was named after a director of the Victorian Squatting Company, Thomas Andrew Drysdale, by the company's surveyor Charles Burrowes, i ...

Freshwater Fish Of Western Australia
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 wate ...
