Redmouth Whalefish
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

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 ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Amphipod
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Guillaume Rondelet
Guillaume Rondelet (27 September 150730 July 1566), also known as Rondeletus/Rondeletius, was Regius professor of medicine at the University of Montpellier in southern France and Chancellor of the University between 1556 and his death in 1566. He achieved renown as an anatomy, anatomist and a naturalist with a particular interest in botany and ichthyology. His major work was a lengthy treatise on marine animals, which took two years to write and became a standard reference work for about a century afterwards, but his lasting impact lay in his education of a roster of star pupils who became leading figures in the world of late-16th century science. Early life and education Rondelet was born in Montpellier in 1507. His father was an , a combination of pharmacist, grocer and druggist. His father died while he was a child and he was brought up in the care of his elder brother.Planchon, J.É. (1866): 11 His health was poor until he reached the age of 18.
