Syncomistes Rastellus
The Drysdale grunter (''Syncomistes rastellus'') is a species of ray-finned fish in the family Terapontidae. It is endemic to Australia, where it occurs in the Gibb and Drysdale Rivers, coastal rivers in northern Western Australia Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Aust ....

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

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 ...

Endemism
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 b ...

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.

Drysdale River
The 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 A tributary, or an ''affluent'', is a stream or river that flows into a larger stream ('' main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean.

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. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1978
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish ...
