Lepidotrigla Brachyoptera
The scaly gurnard (''Lepidotrigla brachyoptera'') is a species of marine, demersal ray-finned fish from the family Triglidae, the gurnards and sea robins. It is found in the south-western Pacific Ocean. Taxonomy The scaly gurnard was first formally described in 1872 by the English-born New Zealand scientist Frederick Wollaston Hutton with its type locality given as Wellington Harbour. The specific name ''brachyoptera'' is a compound of ''brachys'', meaning "short", and ''ptera'', which means "finned", thought to be an allusion to the shorter pectoral fin filaments in comparison to other then described species from the genus ''Lepidotrigla''. Description The scaly gurnard has a body which is covered with large scales that are firmly attached to the skin. There are 10 to 12 scale rows from the lateral line the origin of the anal fin. The upper head and body are reddish with darker mottles, the flanks and lower body are silvery white. There is a dark red blotch on the first d ...

Auckland Museum
The Auckland War Memorial Museum Tāmaki Paenga Hira (or simply the Auckland Museum) is one of New Zealand's most important museums and war memorials. Its collections concentrate on New Zealand history (and especially the history of the Auckland Region), natural history, and military history. The present museum building was constructed in the 1920s in the neo-classicist style, and sits on a grassed plinth (the remains of a dormant volcano) in the Auckland Domain, a large public park close to the Auckland CBD. Auckland Museum's collections and exhibits began in 1852. In 1867 Aucklanders formed a learned society – the Auckland Philosophical Society, later the Auckland Institute. Within a few years the society merged with the museum and '' Auckland Institute and Museum'' was the organisation's name until 1996. Auckland War Memorial Museum was the name of the new building opened in 1929, but since 1996 was more commonly used for the institution as well. From 1991 to 2003 the m ...

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Demersal Fish
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidotrigla Robinsi
''Lepidotrigla'' is a genus of marine ray-finned fishes belonging to the family Triglidae, the gurnards and sea robins. These gurnards are found in the Eastern Atlantic, Indian and Western Pacific Oceans. Taxonomy ''Lepidotrigla'' was first described as a genus in 1860 by the German-born British herpetologist and ichthyologist Albert Günther with ''Trigla aspera'', which had been described in 1829 from the Mediterranean Sea by Georges Cuvier, as the type species. The genus is classified within the subfamily Triglinae, the nominate subfamily of the family Triglidae. The genus name prefixes ''Trigla'', the type genus of the Triglidae. with ''lepido'', "scaled", a reference to the larger scales on these gurnards in comparison to those on ''Trigla''. Species ''Lepidotrigla'' is the most speciose genus in the Triglidae and has 58 species classified within it: * ''Lepidotrigla abyssalis'' D. S. Jordan & Starks, 1904 * ''Lepidotrigla alata'' ( Houttuyn, 1782) * ''Lepidotrigl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kermadec Islands
The Kermadec Islands ( mi, Rangitāhua) are a subtropical island arc in the South Pacific Ocean northeast of New Zealand's North Island, and a similar distance southwest of Tonga. The islands are part of New Zealand. They are in total area and uninhabited, except for the permanently manned Raoul Island Station, the northernmost outpost of New Zealand. The islands are listed with the New Zealand outlying islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead an ''Area Outside Territorial Authority''. Toponymy The islands were named after the Breton captain Jean-Michel Huon de Kermadec, who visited the islands as part of the d'Entrecasteaux expedition in the 1790s. The topographic particle "Kermadec" is of Breton origin and is a lieu-dit in Pencran in Finistère where '' ker'' means village, residence and madec a proper name derived from '' mad'' (which means 'good') with the suffix '' -ec'', used to form adjectives in ...

Chatham Island
Chatham Island ( ) (Moriori: ''Rēkohu'', 'Misty Sun'; mi, Wharekauri) is by far the largest island of the Chatham Islands group, in the south Pacific Ocean off the eastern coast of New Zealand's South Island. It is said to be "halfway between the equator and the pole, and right on the International Date Line", though the point (180°, 45°S) in fact lies ca. 173 miles WSW of the island's westernmost point. The island is called ''Rekohu'' ("misty skies") in Moriori, and ''Wharekauri'' in Māori.Government of New Zealand, Dept. of Conservation (1999) Chatham IslandsConservation Management Strategy''. Retrieved 13 July 2012. The island was named after the survey ship HMS ''Chatham'' which was the first European ship to locate the island in 1791. It covers an area of . Chatham Island lies south-east of Cape Turnagain, the nearest point of mainland New Zealand to the island.

Chatham Rise
The Chatham Rise is an area of ocean floor to the east of New Zealand, forming part of the Zealandia continent. It stretches for some from near the South Island in the west, to the Chatham Islands in the east. It is New Zealand's most productive and important fishing ground, as well as important habitat for whales. Relative to the rest of the Pacific Ocean waters around New Zealand, the Chatham Rise is relatively shallow, no more than deep at any point. This shallowness is made more remarkable by the depth of the ocean immediately to the north and south. To the northeast, the Hikurangi Trench, an extension of the much deeper Kermadec Trench, drops to below close to the New Zealand coast, and further from the coast the Rise borders on the Hikurangi Plateau. To the south, similar depths are achieved in the Bounty Trough. Past the eastern end of the rise, the sea floor drops away to the abyssal plain. Geology Geologically and tectonically, the Chatham Rise can be thought of as ... [...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] |
