Australian Darter
The Australasian darter or Australian darter (''Anhinga novaehollandiae'') is a species of bird in the darter family, Anhingidae. It is found in Australia, Indonesia, and Papua New Guinea. It weighs around 2.6 kg and spans 86–94 cm (34–37 in) in length. Taxonomy John Gould described the Australasian darter as ''Plotus novaehollandiae'' in 1847. Closely related to American (''Anhinga anhinga''), African (''Anhinga rufa''), and Oriental (''Anhinga melanogaster'') darters, the Australasian darter has been classed as a subspecies of the African or African plus Oriental darters. All four have also been classed as a single species. Examination of the leg bones indicates the three Old World species are more closely related to each other with the American species more divergent. Genetic analysis showed it differed from ''A. rufa'' to a degree equivalent to that between other separate species, and shifted consensus to treating the Australasian darter as a separate speci ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor. Gould then be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lesser Sunda Islands
The Lesser Sunda Islands or nowadays known as Nusa Tenggara Islands ( id, Kepulauan Nusa Tenggara, formerly ) are an archipelago in Maritime Southeast Asia, north of Australia. Together with the Greater Sunda Islands to the west they make up the Sunda Islands. The islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea. A bit more than 20 million people live on the islands. Etymologically, Nusa Tenggara means "Southeast Islands" from the words of ''nusa'' which means 'island' from Old Javanese language and ''tenggara'' means 'southeast'. The main Lesser Sunda Islands are, from west to east: Bali, Lombok, Sumbawa, Flores, Sumba, Savu, Rote, Timor, Atauro, Alor archipelago, Barat Daya Islands, and Tanimbar Islands. Geology The Lesser Sunda Islands consist of two geologically distinct archipelagos.Audley-Charles, M.G.

Hydrophilidae
Hydrophilidae, also known colloquially as water scavenger beetles, is a family of beetles. Aquatic hydrophilids are notable for their long maxillary palps, which are longer than their antennae. Several of the former subfamilies of Hydrophilidae have recently been removed and elevated to family rank; Epimetopidae, Georissidae (= Georyssinae), Helophoridae, Hydrochidae, and Spercheidae (= Sphaeridiinae). While the majority of hydrophilids are aquatic, around a third of described species are terrestrial, mostly belonging to the subfamily Sphaeridiinae. With rare exceptions, the larvae are predatory while the adults may be herbivores or predators in addition to scavenging. Many species are able to produce sounds. Species of '' Hydrophilus'' are reported as pests in fish hatcheries. Other species are voracious consumers of mosquito larvae, and have potential as biological control agents. This beetle family contains 2,835 species in 169 genera. Geography Hydrophilid beetles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perca Fluviatilis
The European perch (''Perca fluviatilis''), also known as the common perch, redfin perch, big-scaled redfin, English perch, Euro perch, Eurasian perch, Eurasian river perch, Hatch, poor man’s rockfish or in Anglophone parts of Europe, simply the perch, is a predatory species of the freshwater perch native to Europe and northern Asia. The species is a popular quarry for anglers, and has been widely introduced beyond its native area, into Australia, New Zealand and South Africa. They have caused substantial damage to native fish populations in Australia and have been proclaimed a noxious species in New South Wales. Description European perch are greenish with red pelvic, anal and caudal fins. They have five to eight dark vertical bars on their sides. When the perch grows larger, a hump grows between its head and dorsal fin. European perch can vary greatly in size between bodies of water. They can live for up to 22 years, and older perch are often much larger than average; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philypnodon Grandiceps
The flathead gudgeon (''Philypnodon grandiceps'') is a species of fish in the family Eleotridae endemic to eastern Australia. Taxonomy Gerard Krefft described the flathead gudgeon in 1864 as ''Eleotris grandiceps'', recording it from the Upper Hawkesbury River and its tributaries, and freshwater lagoons near Richmond, Eastern Creek, and Bronte. Alternate names include big-headed gudgeon, bull head, bull-headed gudgeon, collundera, and Yarra gudgeon. Description The flathead gudgeon generally grows to about 8 cm (3.2 in) in length, though large individuals up to 11 or 12 cm (4.5 in) have been recorded. It has a large, flattened head and large mouth, which extends back past the eyes, and two short dorsal fins. The upperparts can be various shades of grey, brown, black, or yellowish, with yellowish underparts.

Acanthopagrus Australis
''Acanthopagrus australis'', the yellowfin bream, also known as sea bream, surf bream, silver bream or eastern black bream, is a species of marine and freshwater fish of the porgy family, Sparidae. It is a deep-bodied fish, occasionally confused with ''Acanthopagrus butcheri'' (black bream), but is generally distinguished by its yellowish ventral and anal fins. It is a popular target for recreational fishermen due to its capacity to fight well above its weight coupled with its table quality. Taxonomy ''A. australis'' is one of 20 species in the genus ''Acanthopagrus'', part of the porgy family Sparidae. The species was first mentioned in scientific literature by Richard Owen in an 1853 work on skeletal material held by the Museum of the Royal College of Surgeons of England. Although he named it ''Chrysophrys australis'', it was insufficiently described and hence designated a ''nomen nudum''. German-British naturalist Albert Günther formally described the surf bream in 1859 using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
