Myliobatis Hamlyni
The purple eagle ray (''Myliobatis hamlyni'') is a species of fish in the family Myliobatidae. It was formerly considered endemic to Australia but is now known to be more widespread. Its natural habitat is the open seas where it has a patchy distribution, and the International Union for Conservation of Nature has assessed its conservation status as being "near-threatened". Taxonomy The purple eagle ray was first described in 1911 by the Australian ichthyologist James Douglas Ogilby as ''Myliobatis hamlyni'', being named in honour of his friend, the entomologist Ronald Hamlyn-Harris, who was director of the Queensland Museum from 1910 to 1917. This eagle ray was originally thought to be endemic to eastern Australia, with other records from the region being ascribed to the closely related Japanese eagle ray (''Myliobatis tobijei''). However a redescription of both species in 2016, including a molecular analysis, indicated that previous records from Western Australia, Indonesia, ...

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. Death Ogilby died on 11 August 1925 at the Diamantina Hospital in Brisbane and was buried at Toowong Cemetery. Legacy Numerous species of fish were named in Ogilby's honor: *''Callionymus ogilbyi'' (Rayfinned Fish) *''Calliurichthys ogilbyi'' (Ogilby’s Stinkfish) *''Cynoglossus ogilbyi'' (Tongue Sole) ...

Whip
A whip is a blunt weapon or implement used in a striking motion to create sound or pain. Whips can be used for flagellation against humans or animals to exert control through pain compliance or fear of pain, or be used as an audible cue through the distinct whipcrack effect. The portion used for striking is generally either a firm rod designed for direct contact, or a flexible line requiring a specialized swing. The former is easier and more precise, the latter offers longer reach and greater force. Some varieties, such as a hunting whip or lunge whip, have an extended stock section in addition to the line. Whips such as the "cat o' nine tails" and knout are specifically developed for corporal punishment or torture on human targets. Certain religious practices and BDSM activities involve the self-use of whips or the use of whips between consenting partners. Misuse on animals may be considered animal cruelty, and misuse on humans may be viewed as assault. Use Whips are genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1911
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Myliobatis
''Myliobatis'' is a genus of eagle rays in the family (biology), family Myliobatidae. Description ''Myliobatis'' species can reach a width up to about . Their bodies consist of a rhomboidal disc, wider than long, with one dorsal fin. The head is broad and short, with eyes and spiracles on the sides. The tail is slender, with one or two large spines at the base, without tail fin. The teeth are arranged in the lower and upper jaws in flat tooth plates called pavement teeth, each consisting of about seven series of plates, which are used to crush clam shells and crustaceans. Biology ''Myliobatis'' species are Ovoviviparity, ovoviviparous. Their gestation lasts about six months, and a female produces four to seven embryos. ''Myliobatis'' species mainly feed on molluscs, bottom-living crustaceans, and small fishes. Habitat ''Myliobatis'' species live in warm, shallow waters. Adults prefer sandy shores, while juveniles can usually be encountered offshore. Species Extant species Curr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threat
A threat is a communication of intent to inflict harm or loss on another person. Intimidation is a tactic used between conflicting parties to make the other timid or psychologically insecure for coercion or control. The act of intimidation for coercion is considered a threat. Threatening or threatening behavior (or criminal threatening behavior) is the crime of intentionally or knowingly putting another person in fear of bodily injury. Some of the more common types of threats forbidden by law are those made with an intent to obtain a monetary advantage or to compel a person to act against their will. In most U.S. states, it is an offense to threaten to (1) use a deadly weapon on another person; (2) injure another's person or property; or (3) injure another's reputation. Law Brazil In Brazil, the crime of threatening someone, defined as a threat to cause unjust and grave harm, is punishable by a fine or three months to one year in prison, as described in the Brazilian Pe ...

Continental Slope
A continental margin is the outer edge of continental crust abutting oceanic crust under coastal waters. It is one of the three major zones of the ocean floor, the other two being deep-ocean basins and mid-ocean ridges. The continental margin consists of three different features: the continental rise, the continental slope, and the continental shelf. Continental margins constitute about 28% of the oceanic area. Subzones The continental shelf is the relatively shallow water area found in proximity to continents; it is the portion of the continental margin that transitions from the shore out towards to ocean. Continental shelves are believed to make up 7% of the sea floor. The width of continental shelves worldwide varies in the range of 0.03–1500 km. The continental shelf is generally flat, and ends at the shelf break, where there is a drastic increase in slope angle: The mean angle of continental shelves worldwide is 0° 07′, and typically steeper closer to the coa ...

Outer Continental Shelf
The Outer Continental Shelf (OCS) is a legally defined geographic feature of the United States. The OCS is the part of the internationally recognized continental shelf of the United States which does not fall under the jurisdictions of the individual U.S. states. The exclusive economic zone of the United States extends from the coast, and thus overlaps but is not coterminous with the Outer Continental Shelf. Definition Formally, the OCS is governed by Title 43 of the United States Code, Title 43, Chapter 29 "Submerged Lands", Subchapter III "Outer Continental Shelf Lands", of the United States Code, U.S. Code which was created under the Outer Continental Shelf Act enacted by the 83rd United States Congress and signed into law by President Dwight D. Eisenhower in 1953. The term "outer Continental Shelf" refers to all submerged land, its subsoil and seabed that belong to the United States and are lying seaward and outside the states' jurisdiction, the latter defined as the "la ...

Subtropics
The subtropical zones or subtropics are geographical and climate zones immediately to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° to 40° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical (Köppen climate classification: Cfa/Cwa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Köppen climate classification: Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau an ...
