Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 1879. Jordan moved to Indiana University, ...

Frank Cramer
Frank Cramer (b. Wausau, Wisconsin November 4, 1861, d. Santa Clara County, California January, 30 1948) was an American writer, biologist and educator. Cramer was born on November 4, 1861 in Wausau, Wisconsin. He attended Lawrence College in Appleton, Wisconsin, from where he graduated in 1886. He was then employed as a teacher in Wisconsin before going on to attend Stanford University in Palo Alto. At Stanford he studied zoology, graduating with a master’s degree in 1893. He was influenced by David Starr Jordan to found a College-preparatory school for Stanford University, opening in 1891. The school was called the Palo Alto Preparatory School for Boys for a short period, until in 1893 it was renamed Manzanita Hall. 24 students were enrolled into the school by September 1894. Cramer remained there as head of school between 1893 and 1902 when he sold it to Dixon Lee. He was one of Palo Alto’s first residents and was one of Palo Alto's early leaders in local government and ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...

Argyripnus
''Argyripnus'' is an oceanic ray-finned fish genus in the marine hatchetfish family Sternoptychidae. They are commonly known as bristle-mouth fishes, but that may also refer to the related bristlemouth family (Gonostomatidae). ''A. iridescens'' is called " pearlside", which usually refers to the closely related genus '' Maurolicus''. Species There are currently seven recognized species in this genus: * '' Argyripnus atlanticus'' Maul, 1952 * '' Argyripnus brocki'' Struhsaker, 1973 (Brock's Bristle-mouth Fish) * '' Argyripnus electronus'' Parin, 1992 * '' Argyripnus ephippiatus'' C. H. Gilbert & Cramer, 1897 (Gilbert & Cramer's Bristle-mouth Fish) * '' Argyripnus hulleyi'' Quéro, Spitz & Vayne, 2009 (Reunion bristle-mouth fish) * '' Argyripnus iridescens'' McCulloch, 1926 (Brilliant Pearlside) * '' Argyripnus pharos'' Harold & Lancaster, 2003 Fossils of bristle-mouth fishes show that the genus was already distinct in the Late Oligocene, more than 23 million years ago ...

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

Taxa Named By Charles Henry Gilbert
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1897
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods ...
