Rondeletiidae
The redmouth whalefishes are two species of deep-sea whalefishes in the genus ''Rondeletia'', the only genus in the family Rondeletiidae. They are apparently close to the velvet whalefish (''Barbourisia rufa''), and apparently also to the gibberfishes (Gibberichthyidae). The latter and the Rondeletiidae are the only known living fishes which have the mysterious Tominaga's organ. Like the plant genus of the same name, this genus is named after Guillaume Rondelet. Redmouth whalefishes are small fishes. ''Rondeletia bicolor'' grows to about 6 cm long or so. It is most commonly found in the northern Atlantic, but has been documented from the eastern Pacific, as well, and presumably also occurs in the rest of the Atlantic. The better-known ''Rondeletia loricata'' is known from all oceans between 47°N–47°S; it has been recorded to reach a length of more than 9 cm when adult. Usually found in deep waters of tropical and temperate oceans around the world, down to 3,000& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whalefish
The Cetomimiformes or whalefishes are an order of small, deep-sea ray-finned fish. Some authoritiesE.g. Nelson (2006) include the whalefishes as part of the order Stephanoberyciformes, within the superfamily Cetomimoidea. Their sister order, the Beryciformes, includes the flashlight fish and squirrelfish. Within this group are five families and approximately 18 genera and 32 species (but see below). Thought to have a circumglobal distribution throughout the tropical and temperate latitudes, whalefishes have been recorded at depths in excess of 3,500 metres. Description Named after their whale-shaped body (from the Greek ''ketos'' meaning "whale" or "sea monster", ''mimos'' meaning "imitative" and the Latin ''forma'' meaning "form"), the Cetomimiformes have extremely large mouths and highly distensible stomachs. Their eyes are very small or vestigial; the lateral line (composed of huge, hollow tubes) is consequently very well developed to compensate for life in the pitch black de ...

Notochord
In anatomy, the notochord is a flexible rod which is similar in structure to the stiffer cartilage. If a species has a notochord at any stage of its life cycle (along with 4 other features), it is, by definition, a chordate. The notochord consists of inner, vacuolated cells covered by fibrous and elastic sheaths, lies along the anteroposterior axis (''front to back''), is usually closer to the dorsal than the ventral surface of the embryo, and is composed of cells derived from the mesoderm. The most commonly cited functions of the notochord are: as a midline tissue that provides directional signals to surrounding tissue during development, as a skeletal (structural) element, and as a vertebral precursor. In lancelets the notochord persists throughout life as the main structural support of the body. In tunicates the notochord is present only in the larval stage, being completely absent in the adult animal. In these invertebrate chordates, the notochord is not vacuolated. In all ...

George Brown Goode
George Brown Goode (February 13, 1851 – September 6, 1896), was an American ichthyologist and museum administrator. He graduated from Wesleyan University and studied at Harvard University. Early life and family George Brown Goode was born February 13, 1851, in New Albany, Indiana, to Francis Collier Goode and Sarah Woodruff Crane Goode. He spent his childhood in Cincinnati, Ohio and Amenia, New York. He married Sarah Ford Judd on November 29, 1877. She was the daughter of Orange Judd, a prominent agricultural writer. Together, they had four children: Margaret Judd, Kenneth Mackarness, Francis Collier, and Philip Burwell. In addition to his scientific publications, Goode wrote Virginia Cousins: A Study of the Ancestry and Posterity of John Goode of Whitby'where he traced his ancestry back to John Goode, a 17th-century colonist from Whitby. Career In 1872, Goode started working with Spencer Baird, soon becoming his trusted assistant. While working with Baird, Goode led researc ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...
