Sladenia Shaefersi
''Sladenia shaefersi'', the Atlantic twospine goosefish or Shaefer's anglerfish, is a species of marine ray-finned fish belonging to the family Lophiidae, the goosefishes, monkfishes and anglers. This species is found in the western Atlantic Ocean. Taxonomy ''Sladenia shaefersi'' was first formally described in 1976 by the American ichthyologists John H. Caruso and Harvey R. Bullis with its type locality given as Point Barú on the Caribbean coast of Colombia. The genus '' Sladenia'' is one of 4 extant genera in the family Lophiidae which the 5th edition of ''Fishes of the World'' classifies in the monotypic suborder Lophioidei within the order Lophiiformes. Etymology ''Sladenia gardineri'' has the genus name ''Sladenia'' which honors Percy Sladen, the British echinoderm biologist. The holotype of ''S. gardineri'' was collected during an expedition funded by his memorial trust. The specific name ''shaefersi'' honors Edward A. Schaefers, the former chief of the Explorat ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blake Plateau
The Blake Plateau lies in the western Atlantic Ocean off the southeastern United States coasts of North Carolina, South Carolina, Georgia and Florida. The Blake Plateau lies between the North American continental shelf and the deep ocean basin extending about east and west by north and south, with a depth of about inshore sloping to about about off shore, where the Blake Escarpment drops steeply to the deep basin. The Blake Plateau, associated Blake Ridge and Blake Basin are named for the U.S. Coast and Geodetic Survey steamer , in service 1874–1905, that first used steel cable for oceanographic operations and pioneered deep ocean anGulf Streamexploration. Survey lines of the steamer ''George S. Blake'' first defined the plateau that now bears the ship's name. History In July 1880 ''George S. Blake'' under the command of Commander John R. Bartlett, U.S.N., was working with sounding gear designed by Lieutenant Commander Sigsbee in cooperation with Alexander Agassiz c ...

Corner Rise Seamounts
The Corner Rise Seamounts are a chain of extinct submarine volcanoes in the northern Atlantic Ocean east of the New England Seamounts. Both it and the New England Seamounts were formed when the North American Plate moved over the Great Meteor hotspot 75 million years ago. It is the shallowest seamount in New England, with some of its nineteen highest peaks only 800–900 m deep. Like most seamounts, they attract fish. Over 175 species have been found there, including splendid alfonsino, black cardinal fish, black scabbardfish, and wreckfish. Trawl fishing during the 1970s and 1980s resulted in approximately 20,000 tons of fish being harvested. As a result, the seamounts were closed to demersal fishing (collecting fish near the bottom of the ocean, as opposed to pelagic fishing, collecting fish near the surface) beginning 1 January 1997. The original ban was supposed to be lifted 31 December 2010, but was extended until 31 December 2020. Almost a decade into the ban, a 2005 Wo ...

Smithsonian Tropical Research Institute
The Smithsonian Tropical Research Institute (STRI, es, Instituto Smithsonian de Investigaciones Tropicales) is located in Panama and is the only bureau of the Smithsonian Institution based outside of the United States. It is dedicated to understanding the past, present, and future of tropical ecosystems and their relevance to human welfare. STRI grew out of a small field station established in 1923 on Barro Colorado Island in the Panama Canal Zone to become one of the world's leading tropical research organizations. STRI's facilities provide for long-term ecological studies in the tropics and are used by some 1,200 visiting scientists from academic and research institutions around the world every year. History Smithsonian scientists first came to Panama during the construction of the Panama Canal from 1904 to 1914. The Secretary of the Smithsonian Institution, Charles Doolittle Walcott, reached an agreement with Federico Boyd to conduct a biological inventory of the new Canal Zo ...

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 ...

Illicium (fish Anatomy)
The anglerfish are fish of the teleost order Lophiiformes (). They are bony fish named for their characteristic mode of predation, in which a modified luminescent fin ray (the esca or illicium) acts as a lure for other fish. The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, that dwell in and around the sea. Some anglerfish are notable for extreme sexual dimorphism and sexual symbiosis of the small male with the much larger female, seen in the suborder Ceratioidei, the deep sea anglerfish. In these species, males may be several orders of magnitude smaller than females. Anglerfish occur worldwide. Some are pelagic (dwelling away from the sea floor), while others are benthic (dwelling close to the sea floor). Some live in the deep sea (such as the Ceratiidae), while others on the continental shelf, such as the frogfishes and the Lophiidae (monkfish or goosefish). Pelagic forms are most often laterally compressed, whereas the benth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
