Frederick Hutton (scientist)
Captain Frederick Wollaston Hutton (16 November 1836 – 27 October 1905) was an English-New Zealand scientist who applied the theory of natural selection to explain the origins and nature of the natural history of New Zealand. An army officer in early life, he then had an academic career in geology and biology. He became one of the most able and prolific nineteenth century naturalists of New Zealand. Biography Hutton was born in Gate Burton, Lincolnshire, England, the son of the Rev. Henry Frederick Hutton and his wife Louisa Wollaston, daughter of the Rev. Henry John Wollaston. He passed through Southwell grammar school and the Naval Academy at Gosport, Hampshire. He studied applied science at King's College London before being commissioned in the Royal Welch Fusiliers and fighting in the Crimean War and the Indian Mutiny. Hutton returned to England in 1860, and continued to study geology at Sandhurst, being elected to the Geological Society of London in the ...

Dory (fish)
The common name ''dory'' (from the Middle English ''dorre'', from the Middle French ''doree'', lit. "gilded one") is shared (officially and colloquially) by members of several different families of large-eyed, silvery, deep-bodied, laterally compressed, and roughly discoid marine fish. As well as resembling each other, dories are also similar in habit: most are deep-sea and demersal. Additionally, many species support commercial fisheries as food fish. Most dory families belong to the order Zeiformes, suborder Zeioidei: *The "true dories", family Zeidae (five species, including the well-known John Dory) *The zeniontids, family Zenionidae or Zeniontidae (seven species) *The "Australian dories", family Cyttidae (three species all within the genus ''Cyttus'') *The oreos, family Oreosomatidae (ten species) *The parazen family, Parazenidae (four species, including the rosy dory) Additionally, several species of spinyfin (family Diretmidae, order Beryciformes) have been given ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 List of islands of New Zealand, smaller islands. It is the List of island countries, sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's Capital of New Zealand, capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the sh ...

Fish Described In 1872
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 ...
