Fitzmaurice River
The Fitzmaurice River is a river in Australia's Northern Territory. Course The river drains into the Joseph Bonaparte Gulf in the Timor Sea from a source just north of the Wombungi homestead. The river flows in a westerly direction between the Wingate mountains to the north and the Yamberra Mountains to the south. The area is quite remote and largely unsettled, and the river itself forms the southern boundary of the township of Wadeye. The estuary formed at the river mouth is tidal in nature and in near pristine condition. Catchment The drainage basin occupies an area of and is wedged between the catchment areas for Victoria River to the south and Moyle River to the north. The river has a mean annual outflow of , Fauna A total of 16 species of fish are found in the river including; the glassfish, Macleay's glassfish, fork-talked catfish, fly-specked hardyhead, mouth almighty, spangled perch, barramundi, oxeye herring, rainbowfish, exquisite rainbowfish, Northern trout ...

Mouth (river)
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

John Lort Stokes
Admiral John Lort Stokes, RN (1 August 1811 – 11 June 1885)Although 1812 is frequently given as Stokes's year of birth, it has been argued by author Marsden Hordern that Stokes was born in 1811, citing a letter by fellow naval officer Crawford Pasco congratulating him on his birthday in 1852. was an officer in the Royal Navy who travelled on for close to eighteen years. Biography Born on 1 August 1811, son of Henry Stokes, of Scotchwell, near Haverfordwest, Pembrokeshire, and Anne, daughter of Dr George Phillips, Stokes joined the Royal Navy on 20 September 1824. The first ship he served on was , and then in October 1825 he joined the crew of ''Beagle'' under Captain Phillip Parker King. ''Beagle'' was involved in a survey of the waters of South America. In 1828 the commander of HMS ''Beagle'', Pringle Stokes (not related to John Lort Stokes), committed suicide and Robert FitzRoy assumed command; the ship returned to England in 1830 and was recommissioned.

Crocodile
Crocodiles (family (biology), family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant taxon, extant members of the order (biology), order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa. Although they appear similar, crocodiles, alligators and the gharial belong to separate biological family (biology), families. The gharial, with its narrow snout, is easier to distinguish, while Morphology (biology), morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head, with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is that the upp ... [...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] |
Bony Bream
Bony bream ''Nematalosa erebi'' are a widespread and common, small to medium-sized Australian freshwater fish often found in large shoals throughout much of northern and central Australia, and the Murray-Darling basin. Description A deep bodied, laterally compressed fish with a blunt snout. Spineless dorsal fin with the posterior ray developedinto a long filament. Usually silver overall, sometimes grey to greenish dorsally. In Victoria it has been reported to develop a rusty red tinge especially around the mouth which is thought to be related to breeding. Some populations develop a dark blotch on the shoulder. Distribution Common and widespread throughout its range, found in the Pilbara, Timor Sea, Gulf of Carpentaria, Northeast Coast, Murray-Darling (at elevations below 200 metres, 650 ft) Are present in Tinaroo Dam, elevation 660m, often referred to as "Barra lollies" because of a tendency for impoundment barramundi to round them up and Lake Eyre Australi ...

Rainbowfish
The rainbowfish or Melanotaeniidae is a family of small, colourful freshwater fish found in northern and eastern Australia, New Guinea (including islands in Cenderawasih Bay and Raja Ampat Islands in Indonesia), Sulawesi and Madagascar. The largest rainbowfish genus, ''Melanotaenia'', derives from the ancient Greek ''melano'' (black) and ''taenia'' (banded). Translated, it means "black-banded", and is a reference to the often striking lateral black bands that run along the bodies of those in the genus ''Melanotaenia''. Characteristics The Melanotaeniidae is characterised by having their distal premaxillary teeth enlarged. They have a compressed body with the two dorsal fins being separated but with only a small gap between them. There are 3–7 spines in the first dorsal fin while the second has 6–22 rays, with the first ray being a stout spine in some species, the anal fin has 10–30 rays and, again, the first may be a stout spine in some species. The lateral line is either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indo-Pacific Tarpon
The Indo-Pacific tarpon (''Megalops cyprinoides''), also known as the oxeye herring or simply herring due to its superficial resemblance to the Clupeidae, true herrings, of which it is not a member, is the smaller of the two species of Megalops, tarpon and lives in Indo-Pacific waters.Adams, A., Guindon, K., Horodysky, A., MacDonald, T., McBride, R., Shenker, J. & Ward, R. 2012. Megalops cyprinoides. In: IUCN 2013. IUCN Red List of Threatened Species. Version 2013.2. [www.iucnredlist.org]. Downloaded on 01 March 2014. Description In appearance, it is like the much larger Atlantic tarpon, ''M. atlanticus'' - olive-green on top, and silver on the sides. The large mouth is turned upwards; the lower jaw contains an elongated, bony plate. The last ray of the dorsal fin is much longer than the others, reaching nearly to the tail. It is capable of filling its swim bladder with air and absorbing oxygen from it. Those living in fresh water tend to be smaller than the ones living in saltwat ...

Barramundi
The barramundi (''Lates calcarifer'') or Asian sea bass, is a species of catadromous fish in the family Latidae of the order Perciformes. The species is widely distributed in the Indo-West Pacific, spanning the waters of the Middle East, South Asia, Southeast Asia, East Asia, and Oceania. Origin of name Barramundi is a loanword from an Australian Aboriginal language of the Rockhampton area in Queensland meaning "large-scaled river fish". Originally, the name barramundi referred to ''Scleropages leichardti'' and ''Scleropages jardinii''. However, the name was appropriated for marketing reasons during the 1980s, a decision that has aided in raising the profile of this fish significantly. ''L. calcarifer'' is broadly referred to as Asian seabass by the international scientific community, but is also known as Australian seabass. Description This species has an elongated body form with a large, slightly oblique mouth and an upper jaw extending behind the eye. The lower edge of th ...
