Notesthes
The bullrout (''Notesthes robusta''), also commonly called freshwater stonefish or kroki, is a pale yellowish to dark-brown coloured fish that lives in tidal estuaries and slow-flowing streams in eastern Australia, from Southern New South Wales to northern Queensland, Australia. It has on a very infrequent occurrence been caught at sea. Its spines are venomous. It is the only member of the genus ''Notesthes''. Taxonomy and etymology The bullrout was first formally described in 1860 as ''Centropogon robustus'' by the German-born British and[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetraroginae
Tetraroginae is a subfamily of marine ray-finned fishes, commonly known as waspfishes or sailback scorpionfishes, belonging to the family Scorpaenidae, the scorpionfishes and their relatives. These fishes are native to the Indian Ocean and the West Pacific. As their name suggests, waspfishes are often venomous; having poison glands on their spines. They are bottom-dwelling fish, living at depths to . These creatures usually live in hiding places on the sea bottom. Taxonomy and etymology Tetraroginae, or Tetrarogidae, was first formally recognised as a taxonomic grouping in 1949 by the South African ichthyologist J.L.B. Smith. The 5th edition of Fishes of the World treats this as a subfamily of the scorpionfish family Scorpaenidae, however other authorities treat it as a valid family, the Tetrarogidae. A recent study placed the waspfishes into an expanded stonefish clade, within the family Synanceiidae, because all of these fish have a lachrymal sabre that can project a switch ...

James Douglas Ogilby
James Douglas Ogilby (16 February 1853 – 11 August 1925) was an Australian ichthyologist and herpetologist. Ogilby was born in Belfast, Ireland, and was the son of zoologist William Ogilby and his wife Adelaide, née Douglas. He received his education at Winchester College, England, and Trinity College, Dublin. Ogilby worked for the British Museum before joining the Australian Museum in Sydney. After being let go for drunkenness in 1890, he picked up contract work before joining the Queensland Museum in Brisbane circa 1903. He was the author of numerous scientific papers on reptiles, and he described a new species of turtle and several new species of lizards. Ogilby died on 11 August 1925 and was buried at Toowong Cemetery Toowong Cemetery is a heritage-listed cemetery on the corner of Frederick Street and Mt Coot-tha Road, Toowong, City of Brisbane, Queensland, Australia.

Eastern Fortescue
The Eastern fortescue (''Centropogon australis''), also known as the fortesque, Southern fortescue, fortie or Southern bullrout, is a species of ray-finned fish, a waspfish belonging to the subfamily Tetraroginae of the family Scorpaenidae, the scorpionfishes and their relatives. It is found the coastal waters of eastern Australia. Taxonomy The Eastern fortescue was first formally described as ''Cottus australis'' in 1790 by the English biologist George Shaw in John White's ''Journal of a voyage to New South Wales''. In 1829 Cuvier and Valenciennes placed this taxon in the genus ''Apistus'' and in 1860 the Albert Günther created the genus ''Centropogon'' which included ''A. australis''. In 1876 Pieter Bleeker designated it as the type species of ''Centropogon''. The specific name ''australis'' means "southern". Description The Eastern fortescue has 15 or 16 spines and 7 to 9 soft rays in the dorsal fin while the anal fin has 3 spines and 5 soft rays. The nasal bones have 2-3 ...

Venomous Fish
Venomous fish are species of fish which produce strong mixtures of toxins harmful to humans (called venom) which they deliberately deliver by means of a bite, sting, or stab, resulting in an envenomation. As a contrast, poisonous fish also produce a strong toxin, but they do not bite, sting, or stab to deliver the toxin, instead being poisonous to eat because the human digestive system does not destroy the toxin they contain in their bodies. Venomous fish do not necessarily cause poisoning if they are eaten, as the digestive system often destroys the venom.Poisonous vs. Venomous fish: What’s the difference? Reef Biosearch. Retrieved 17 July 2009. There are at least 1200 species of venomous fish, Smith WL and Wheeler WC (2006 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambush Predator
Ambush predators or sit-and-wait predators are carnivorous animals that capture or trap prey via stealth, luring or by (typically instinctive) strategies utilizing an element of surprise. Unlike pursuit predators, who chase to capture prey using sheer speed or endurance, ambush predators avoid fatigue by staying in concealment, waiting patiently for the prey to get near, before launching a sudden overwhelming attack that quickly incapacitates and captures the prey. The ambush is often opportunistic, and may be set by hiding in a burrow, by camouflage, by aggressive mimicry, or by the use of a trap (e.g. a web). The predator then uses a combination of senses to detect and assess the prey, and to time the strike. Nocturnal ambush predators such as cats and snakes have vertical slit pupils helping them to judge the distance to prey in dim light. Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expandin ...

Pambula, New South Wales
Pambula is a town in Bega Valley Shire on the far south coast of New South Wales, Australia south of Sydney via the Princes Highway. At the , Pambula had a population of 970 people. History The area was populated by the Thaua Aboriginal people, with shell middens dating back 3000 years. The name Pambula is derived from its Dharwa name, pronounced "panboola", meaning 'twin waters'. In 1797, the European voyager George Bass explored the area. Pambula is a historic village with its first European settlers thought to have been the Imlay brothers who established cattle runs on the Pambula River flats in the 1830s. The village of Pambula situated on the flats near the river was planned in 1843 by surveyor Townsend and the first school and churches were built there, but frequent flooding led to the village being relocated to its present site on higher ground. Captain John Lloyd, RN, acquired land in 1844 with his severance pay when he left the Royal Navy, and built ''The Grange'' ...

Cooktown, Queensland
Cooktown is a coastal town and locality in the Shire of Cook, Queensland, Australia. Cooktown is at the mouth of the Endeavour River, on Cape York Peninsula in Far North Queensland where James Cook beached his ship, the Endeavour, for repairs in 1770. Both the town and Mount Cook (431 metres or 1,415 feet) which rises up behind the town were named after James Cook. Cooktown is one of the few large towns in the Cape York Peninsula and was founded on 25 October 1873 as a supply port for the goldfields along the Palmer River.Pike (1979), p. 23.Holthouse, Hector (1967).

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Length
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.

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] |
Operculum (fish)
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding. Anatomy The opercular series contains four bone segments known as the preoperculum, suboperculum, interoperculum and operculum. The preoperculum is a crescent-shaped structure that has a series of ridges directed posterodorsally to the organisms canal pores. The preoperculum can be located through an exposed condyle that is present immediately under its ventral margin; it also borders the operculum, suboperculum, and interoperculum posteriorly. The suboperculum is rectangular in shape in most bony fishy and is located ventral to the preoperculum and operculum components. It is the thinnest bone segment out of the opercular series and is located directly above the gills. The interoperculum is triangular shaped and borders the suboperculum posterodorsally and the preoperculum anterodorsa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
