Johann Gottlob Theaenus Schneider
Johann Gottlob Theaenus Schneider (18 January 1750 – 12 January 1822) was a German classicist and naturalist. Biography Schneider was born at Collm in Saxony. In 1774, on the recommendation of Christian Gottlob Heine, he became secretary to the famous Strasbourg scholar Richard François Brunck, and in 1811 became professor of ancient languages and eloquence at Breslau (chief librarian, 1816) where he died in 1822. Works Of his numerous works the most important was his ''Kritisches griechisch-deutsches Handwörterbuch'' (1797–1798), the first independent work of the kind since Stephanus's ''Thesaurus'', and the basis of F. Passow's and all succeeding Greek lexicons (including, therefore, the contemporary standard '' A Greek-English Lexicon''). A special improvement was the introduction of words and expressions connected with natural history and science. In 1801 he corrected and expanded re-published Marcus Elieser Bloch's ''Systema Ichthyologiae iconibus cx illustratum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percophidae
The Percophidae, duckbills, are a family of percomorph fishes, from the order Trachiniformes, found in tropical and subtropical waters of the Atlantic and Indian Oceans and in the southwestern and southeastern Pacific. They are small fishes: the largest species, the Brazilian flathead, ''Percophis brasiliensis'', grows up to about , but to is more typical. A few species are fished commercially, including the Brazilian flathead. Characteristics The species in the family Percophidae are elongated, benthic fishes with an anteriorly depressed head, a broad flat snout which gives rise to the common name duckbills. The mouth is large with a prognathous lower jaw and exposed maxilla. They have large closely placed eyes. There are two spines on the opercula and one on subopercula. They have tiny conical teeth on the mandibles and on the vomer and palatine bones. There are two dorsal fins an anterior dorsal fin with 6 slender spines and a posterior dorsal fin with 13 to 18 soft rays, ...

Wade Doak
Wade Thomas Doak (23 February 1940 – 12 September 2019) was a New Zealand marine conservationist, scuba diver, photographer and filmmaker. Born in Christchurch, Doak was educated at Christchurch Boys' High School from 1954 to 1958. He began diving in his teens, and met Kelly Tarlton at the Canterbury Underwater Club. In the 1960s, Doak moved to Northland, where he first dove around the Poor Knights Islands with Tarlton. Doak became an acknowledged expert on the marine ecology of the area, and was instrumental in the Poor Knights Islands being made a marine reserve in 1981 and receiving full protection in 1998. In the 2012 Queen's Birthday and Diamond Jubilee Honours, Doak was awarded the Queen's Service Medal, for services to marine conservation. He died at his home in Ngunguru Ngunguru is a coastal settlement in Northland, New Zealand, north-east of Whangārei.

Endemic Marine Fish Of New Zealand
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1801
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. Most fis ...
