Ctenoid
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoid scales. Some species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archerfish
The archerfish (spinner fish or archer fish) form a monotypic family, Toxotidae, of fish known for their habit of preying on land-based insects and other small animals by shooting them down with water droplets from their specialized mouths. The family is small, consisting of ten species in a single genus, ''Toxotes''. Most species live in fresh water rivers, streams and pools, but two or three are euryhaline, inhabiting both fresh and brackish water habitats such as estuaries and mangroves. They can be found from India, Bangladesh and Sri Lanka, through Southeast Asia, to Northern Australia and Melanesia. Archerfish or spinnerfish bodies are deep and laterally compressed, with the dorsal fin, and the profile a straight line from dorsal fin to mouth. The mouth is protractile, and the lower jaw juts out. Sizes are fairly small, typically up to about , but ''T. chatareus'' can reach . Archerfish are popular for aquaria, but difficult to feed since they prefer live prey. Captu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geikie Gorge National Park
Danggu (Geikie) Gorge National Park is a national park in the Kimberley region of Western Australia, (great-circle distance) northeast of Perth and approximately east of Broome by road. The gorge was originally named in honour of Sir Archibald Geikie, the Director General of Geological Survey for Great Britain and Ireland when it was given its European name in 1883. Geikie never visited the gorge and the National Park is progressively being officially changed to the Bunubathe traditional owners of the areaname of Danggu. It is part of the Balili (Devonian Reef) Conservation Park. The park is one of the most accessible in the Kimberley as it is only from Fitzroy Crossing and is serviced by a sealed road. No camping is allowed in the park and visitors can only enter during the day. The park has picnic shelters, barbecue areas, toilets and water available. A walk trail exists along the western base of the gorge walls; although the terrain is rough and uneven it does offer an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seawater
Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measurement ...

Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gr ...

Banded Archerfish
The banded archerfish (''Toxotes jaculatrix'') is a brackish water perciform fish of the archerfish genus ''Toxotes''. It is silvery in colour and has a dorsal fin towards the posterior end. It has distinctive, semi-triangular markings along its sides. It is best known for its ability to spit a jet of water to "shoot down" prey. Larger specimens may be able to hit prey away. The banded archerfish may reach the displaced prey within 50 milliseconds of its hitting the water. The name (binomial as well as common) refers to Sagittarius the archer, because of the unusual method banded archerfish use to capture prey. Banded archerfish are found in Indo-Pacific and Oceanian waters, generally in river mouths and mangrove estuaries. They move between fresh, salt, and brackish water over the course of their lifetime, though not to breed. Because of their markings and silvery colour, banded archerfish are sometimes kept as aquarium fish, though they are difficult to care for and not rec ...

Seven-spot Archerfish
''Toxotes chatareus'', sometimes known by the common names common archerfish, seven-spot archerfish or largescale archerfish, is a species of perciform fish in the archerfish genus ''Toxotes''.Martin F. Gomon & Dianne J. Bray (2011Sevenspot Archerfish, Toxotes chatareus Fishes of Australia. Retrieved 29 Aug 2014 They are usually no larger than but may grow up to . Unlike most archerfish, ''T. chatareus'' are sooty rather than silvery in colour. They are omnivorous, feeding on insects, fish, and vegetative matter at the surface of the water. Breeding occurs in the wet season, and 20,000 to 150,000 eggs may be laid at one time. ''T. chatareus'' are distributed throughout southeast Asia and the Indo-Pacific and Australia. They may live in brackish or fresh water, inhabiting mangrove swamps and estuaries as well as further upstream in slow-moving rivers. While occasionally caught and eaten, ''T. chatareus'' are more commonly kept in the aquarium. They may be sold w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
May River
The May River is a river in the Kimberley region of Western Australia. The river is formed when the Lennard River splits into two channels north of Mount Marmion and near the Kimberley Downs Station homestead, the other channel being the Meda River. It continues to flow west north-westward through Poulton Pool until it eventually discharges into Stokes Bay, King Sound which is north-east of Derby. The river was named in 1881 by a pioneer of the area, George Julius Brockman, during an expedition in the Kimberley area looking for grazing land north of the Fitzroy River. He named the river after the granddaughter of John Septimus Roe, Mary Matilda (May) Thomson. The only tributaries of the May and the Lennard and Camiara Creek. The northern river shark is known to inhabit the tidal region of the river and has been found further upstream. Barramundi and cherabin are also caught in the river pools after the wet season The wet season (sometimes called the Rainy season) i ...

Meda River
The Meda River is a river in the Kimberley region of Western Australia. The river is formed when the Lennard River splits into two channels just north of Mount Marmion, the other channel being the May River. Continuing to flow westward the river eventually discharges into Stokes Bay, King Sound which is north-east of Derby. The river was named in 1881 by a pioneer of the area, George Julius Brockman during an expedition in the Kimberley area. The river is named after ''HMS Meda'', an Admiralty surveying vessel that charted the coastline in the area including the river mouth in 1880. The traditional owners of the areas around the river are the Ongkarango people. The Meda has three tributaries, the Lennard River Lennard River is a river in the Kimberley region of Western Australia.

Fitzroy River (Western Australia)
The Fitzroy River is located in the West Kimberley region of Western Australia. It has 20 tributaries and its catchment occupies an area of , within the Canning Basin and the Timor Sea drainage division. It often floods extensively during the wet season, and is known as the major remaining habitat for the critically endangered sawfish. History Pre-colonisation The first people to live along the river were the traditional owners of the areas around the river, including the Bunuba and Nyikina people to the west, and the Walmajarri and Gooniyandi people to the east, who have lived in the area for at least 40,000 years. The Nyikina and Bunuba people know the river as ''Mardoowarra'' and Bandaral Ngarri respectively; the river and its vast floodplains are of great spiritual, cultural, medicinal and ecological significance. The Nyikina word ''Raparapa'', translates as "alongside the river". 19th to 21st centuries The first European to visit the Fitzroy River was George Grey in 1 ...
