Bostockia Porosa
The nightfish (''Bostockia porosa'') is a species of freshwater ray-finned fish, a temperate perch from the family Percichthyidae which is endemic to southwestern Australia. Taxonomy The nightfish was first formally described in 1873 by the French naturalist François-Louis Laporte, comte de Castelnau. The type locality was given as the Cygnes River in the interior of Western Australia. Castelnau also described the new monotypic genus ''Bostockia'' for this new species. The is genus is classified within the family Percichthyidae, the temperate perches. The genus name honours the Anglican minister Rev. George James Bostock (1833-1881), a collector of fish specimens for Castelnau in Western Australia, he collected the nightfish type. The specific name ''porosus'' means “holed” or “pored”, an allusion to the pores around the head. Description The nightfish has an oblong and compressed body with a large, oblique mouth which has a slightly protruding lower jaw ...

Minister (Christianity)
In Christianity, a minister is a person authorised by a church body, church or other religious organization to perform functions such as teaching of beliefs; leading services such as weddings, baptisms or funerals; or otherwise providing spiritual guidance to the community. The term is taken from Latin ''minister'' ("servant", "attendant"). In some church traditions the term is usually used for people who have ordained, but in other traditions it can also be used for non-ordained people who have a pastoral or liturgical ministry. In Catholic, Orthodox (Eastern Orthodox, Eastern and Oriental Orthodox, Oriental), Anglican and Lutheran churches, the concept of a priesthood is emphasized. In other denominations such as Baptist, Methodist and Calvinist churches (Congregationalist and Presbyterian), the term "minister" usually refers to a member of the ordination, ordained clergy who leads a congregation or participates in a role in a parachurch ministry; such a person may serve as ...

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albany, Western Australia
Albany ( ; nys, Kinjarling) is a port city in the Great Southern region in the Australian state of Western Australia, southeast of Perth, the state capital. The city centre is at the northern edge of Princess Royal Harbour, which is a part of King George Sound. The central business district is bounded by Mount Clarence to the east and Mount Melville to the west. The city is in the local government area of the City of Albany. While it is the oldest colonial, although not European, settlement in Western Australia - predating Perth and Fremantle by over two years - it was a semi-exclave of New South Wales for over four years until it was made part of the Swan River Colony. The settlement was founded on 26 December 1826 as a military outpost of New South Wales for the purpose of forestalling French ambitions in the region. To that end, on 21 January 1827, the commander of the outpost, Major Edmund Lockyer, formally took possession for the British Crown of the portion of N ...

Kalgan River
The Kalgan River is a river in the Great Southern region of Western Australia. Geography The river is long and, along with the King River, drains into Oyster Harbour. The lower 9 km of the river take the form of a drowned river valley with steep hillsides of forest and farmland, and the occasional outcrop of granite. The river's source is west of the Stirling Ranges. It rises north-west of Kendenup and flows generally southwards until it reaches Oyster Harbour about 10 km north-east of Albany. The Kalgan River is the region’s fourth largest river in terms of average annual flow (53,400 megalitres), and has the third largest catchment area (2,562 km²). The upper reaches of the Kalgan River lie within the National Park. These tributaries are marginally saline to brackish, suggesting the levels of salinity are natural. The loss of catchment vegetation (66% of the catchment is cleared) has increased salinity levels downstream. The lower section of the ...

Hill River (Western Australia)
Hill River is a river in the Wheatbelt region of Western Australia. Geography The headwaters of the Hill River rise near Dinner Hill, approximately east of Badgingarra. It then flows in a westerly direction, crossing the Brand Highway just north of Badgingarra, passing through the Hill River Nature Reserve and the northern boundary of the Southern Beekeeper's Nature Reserve and finally discharging into the Indian Ocean south of Jurien Bay. The river has four tributaries; Coomallo Creek, Winjardie Creek, Munbinea Creek and Boothendara Creek. History The river was seen and named by the explorer George Grey on 14 April 1839 during his second disastrous expedition along the Western Australian coast. It was likely named after Rowland Hill, well known for his inception of the Uniform Penny Post, but importantly for Grey, Secretary to the Colonization Commissioners for South Australia (under the South Australia Act 1834). Grey's friend and promoter William Hutt M.P. was als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot, as well as Kwongan. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20-120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regio ... [...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] |
Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
