Draconettidae
The Draconettidae, slope dragonets, are a small family (about 12-14 species) of fish in the order Perciformes. They are found in temperate to tropical waters of the Atlantic, Indian Ocean, Indian and western Pacific Oceans. They are closely related to, and appear similar to, the fish of the Callionymidae. They are small fish, the largest species reaching long. Like the callionymids, they are bottom-dwelling fish, and usually sexual dimorphism, sexually dimorphic. Ecology and behavior Not much is known about the ecology of slope dragonets. The Ichthyoplankton, larvae are planktonic, while adults live in the benthic zone on soft bottoms from the edge of the Continental_shelf#Topography, outer continental shelf and on seamounts down to around deep.

Callionymidae
Dragonets are small percomorph marine fish of the diverse family Callionymidae (from the Greek ''kallis'', "beautiful" and ', "name") found mainly in the tropical waters of the western Indo-Pacific. They are benthic organisms, spending most of their time near the sandy bottoms, at a depth of roughly two hundred meters. There exist 139 species of the fish, in nineteen genera. Due to similarities in morphology and behavior, dragonets are sometimes confused with members of the goby family. However, male dragonets can be differentiated from the goby by their very long dorsal fins, and females by their protruding lower jaws. The Draconettidae may be considered a sister family, whose members are very much alike, though rarely seen. Genera The following genera are classified within the Callionymidae: * '' Anaora'' J. E. Gray, 1835 * '' Bathycallionymus'' Nakabo, 1982 * ''Callionymus'' Linnaeus, 1758 (including '' Calliurichthys'') * '' Diplogrammus'' Gill, 1865 (including ''Chalin ...

Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

South African Institute For Aquatic Biodiversity
The South African Institute for Aquatic Biodiversity (SAIAB), is involved in research, education and in applications of its knowledge and research to African fish fauna, for either economic or conservation benefit. The institute originally established in 1969, was formerly named the JLB Smith Institute of Ichthyology, in honour of Professor James Leonard Brierley Smith, who named and described the living coelacanth ''Latimeria chalumnae''. The JLB Smith Institute of Ichthyology received recognition as a national research entity, renamed as the South African Institute of Aquatic Biodiversity in 1999. Situated in Makhanda, Eastern Cape, the South African Institute for Aquatic Biodiversity (SAIAB) is an internationally recognised centre for the study of aquatic biodiversity. As a National Facility of the NRF, SAIAB serves as a major scientific resource for knowledge and understanding the biodiversity and functioning of globally significant aquatic ecosystems.

Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Philadelphia, Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934, he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Drexel University, Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men devel ...

Sexual Dimorphism
Sexual dimorphism is the condition where sexes of the same species exhibit different Morphology (biology), morphological characteristics, including characteristics not directly involved in reproduction. The condition occurs in most dioecy, dioecious species, which consist of most animals and some plants. Differences may include secondary sex characteristics, size, weight, color, markings, or behavioral or cognitive traits. Male-male reproductive competition has evolved a diverse array of sexually dimorphic traits. Aggressive utility traits such as "battle" teeth and blunt heads reinforced as battering rams are used as weapons in aggressive interactions between rivals. Passive displays such as ornamental feathering or song-calling have also evolved mainly through sexual selection. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', when both biological sexes are phenotype, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
