Ambassis Jacksoniensis
''Ambassis jacksoniensis'', commonly known as the Port Jackson glassfish or Port Jackson perchlet, is a species of fish in the family Ambassidae native to eastern Australia. It gains its common name from its transparent appearance. Taxonomy William John Macleay described the Port Jackson glassfish as ''Pseudambassis jacksoniensis'' in 1881 from a specimen collected in Port Jackson, noting that the length was three and a third times the fishes' height. The species name relates to the location it was described. It was classified in the new genus ''Velambassis'' by Gilbert Whitley in 1935, on the basis of having weaker dorsal spines than other members of the family. Allen and Burgess found no reason for the species not to be in the genus ''Ambassis'' and reassigned it there in 1990. This species and the co-occurring estuary glassfish ('' A. marianus'') are the only two members of the genus found in temperate waters. The others are found in the waters of northern Australia and south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William John Macleay
Sir William John Macleay (13 June 1820 – 7 December 1891) was a Scottish-Australian politician, Natural history, naturalist, zoologist, and Herpetology, herpetologist. Early life Macleay was born at Wick, Highland, Wick, Caithness, Scotland, second son of Kenneth Macleay of Keiss and his wife Barbara, ''née'' Horne. Macleay was educated at the Edinburgh Academy 1834–36 and then to studied medicine at the University of Edinburgh; but when he was 18 years old his widowed mother died, and he decided to go to Australia with his cousin, William Sharp MacLeay. They arrived at Sydney in March 1839 on HMS Royal George (1827), HMS ''Royal George''. William Macleay took up land at first near Goulburn, New South Wales, Goulburn, and afterwards on the Murrumbidgee River. He is noted as the last of the naturalists in a family active in this field; his uncle was Alexander Macleay, Colonial Secretary of New South Wales from 1826 to 1836, and a member and fellow of societies concerned wit ...

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 arthropods. Mos ...

Ambassidae
The Asiatic glassfishes are a family, the Ambassidae, of freshwater and marine fishes that were formerly classified in the order Perciformes, but most authorities consider this order to be paraphyletic and that the Ambassidae are of uncertain affinities, ''incertae sedis'', but within the subseries Ovalentaria. The species in the family are native to Asia, Oceania, the Indian Ocean, and the western Pacific Ocean. The family includes eight genera and about 51 species. The largest species reaches a maximum size around 26 cm (10 in). Many of the species are noted for their transparent or semitransparent bodies. Several species are used as aquarium fish, noted for their transparent bodies. The Indian glassy fish (''Parambassis ranga'') is transparent, but showier specimens that had been injected with artificial coloring were sold as novelty pets in the 1990s. Since then, these "painted fish" have become much less popular, with more fishkeepers seeking naturally pigmente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert Percy Whitley
Gilbert Percy Whitley (9 June 1903 – 18 July 1975) was a British-born Australian ichthyologist and malacologist who was Curator of Fishes at the Australian Museum in Sydney for about 40 years. He was born at Swaythling, Southampton, England, and was educated at King Edward VI School, Southampton and the Royal Naval College, Osborne. Whitley migrated with his family to Sydney in 1921 and he joined the staff of the Australian Museum in 1922 while studying zoology at Sydney Technical College and the University of Sydney. In 1925 he was formally appointed Ichthyologist (later Curator of Fishes) at the Museum, a position he held until retirement in 1964. During his term of office he doubled the size of the ichthyological collection to 37,000 specimens through many collecting expeditions. Whitley was also a major force in the Royal Zoological Society of New South Wales, of which he was made a Fellow in 1934 and where he served as president during 1940–41, 1959–60 and 1973–74. ...

Ambassis
''Ambassis'' is a genus of fish in the family Ambassidae, the Asiatic glassfishes. They are found widely in the Indo-Pacific region, with species in fresh, brackish and coastal marine waters. This genus includes fish known commonly as glassies, perchlets, and common glassfishes. The genus name was derived from the Greek ''anabasis'', meaning 'climbing up'. Species There are currently 20 recognized species in this genus: * ''Ambassis agassizii'' Steindachner, 1867 – Agassiz's olive glassfish * ''Ambassis agrammus'' Günther, 1867 – sailfin glass perchlet * ''Ambassis ambassis'' ( Lacépède, 1802) – Commerson's glassy * ''Ambassis buruensis'' Bleeker, 1856 – Buru glass perchlet * ''Ambassis buton'' Popta, 1918 – Buton glassy perchlet * ''Ambassis dussumieri'' G. Cuvier, 1828 – Malabar glassy perchlet * ''Ambassis elongatus'' ( Castelnau, 1878) – yellowfin glassfish * ''Ambassis fontoynonti'' Pellegrin, 1932 – dusky glass perch * ' ...

Ambassis Marianus
''Ambassis marianus'', commonly known as the estuary perchlet, Ramsay's glassfish, estuary glassfish or glass perchlet, is a species of fish in the family Ambassidae. It is native to coastal eastern Australia. It gains its common name from its transparent appearance. Taxonomy German-British naturalist Albert Günther described ''Ambassis marianus'' in 1880 from a specimen collected from the Mary River near the village of Tiaro, some twenty miles upstream from Maryborough, on an expedition in May 1874. William John Macleay described a specimen from Port Jackson (Sydney) as ''Pseudoambassis ramsayi''. Charles Walter De Vis described ''Pseudoambassis convexus'' from a Queensland specimen in 1884. Both of these are now regarded as synonyms of ''Ambassis marianus''. This species and the co-occurring Port Jackson glassfish ('' A. jacksoniensis'') are the only two members of the genus found in temperate waters. The others are found in the waters of northern Australia and southeast Asia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Scale
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 are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moreton Bay
Moreton Bay is a bay located on the eastern coast of Australia from central Brisbane, Queensland. It is one of Queensland's most important coastal resources. The waters of Moreton Bay are a popular destination for recreational anglers and are used by commercial operators who provide seafood to market. The Port of Brisbane coordinates large traffic along the shipping channel which crosses the northern section of the bay. The bay serves as a safe approach to the airport and reduces noise pollution over the city to the west of the runway. A number of barge, ferry and water-taxi services also travel over the bay. Moreton Bay was the site of conflict between the Quandamooka people and early European settlers. It contains environmentally significant habitats and large areas of sandbanks. The bay is the only place in Australia where dugong gather into herds. Many parts of the mainland foreshore and southern islands are settled. The waters of Moreton Bay are relatively calm, being s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narooma, New South Wales
Narooma is a town in the Australian state of New South Wales on the far south coast. The town is on the Princes Highway, which crosses the Wagonga Inlet to North Narooma. The heritage town of Central Tilba is nearby to the south. The name Narooma is said to be derived from a word in the local Aboriginal language (one of the Yuin dialects) meaning "clear blue waters". At the , Narooma had an urban population of over 3,000 people. History Before European settlement of the area, the Yuin people inhabited the lands along the stretch of coast, with the Walbunga/Walbunja clan being the traditional owners of the Narooma area. The name Narooma is said to be derived from a word in the local Aboriginal language meaning "clear blue waters". The language of the Walbunja was probably a dialect of Dhurga. There had been an earlier settlement nearby at Punkalla, which was a port for Bodalla and Nerrigundah; a ruined jetty and timber mill can still be seen there. Gold was discov ...

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Little Pied Cormorant
The little pied cormorant, little shag or kawaupaka (''Microcarbo melanoleucos'') is a common Australasian waterbird, found around the coasts, islands, estuaries, and inland waters of Australia, New Guinea, New Zealand, Thailand, Myanmar, Singapore, Brunei, Timor Leste, and Indonesia, and around the islands of the south-western Pacific and the subantarctic. It is a small short-billed cormorant usually black above and white below with a yellow bill and small crest, although a mostly black white-throated form predominates in New Zealand. Three subspecies are recognised. Until recently most authorities referred to this species as ''Phalacrocorax melanoleucos''. Taxonomy The species is known as the little pied cormorant in Australia, and as the little shag or by the Māori name of kawaupaka in New Zealand. The term white-throated shag is also reserved for the melanistic form there. The little pied cormorant was originally described by French naturalist Louis Jean Pierre Vieillot in ...
