William Harding Longley
William Harding Longley (1881–1937) was an American botanist. Biography Longley was born in 1881 in Nova Scotia. He attended Acadia and Yale. From 1911 to 1937, he spent as a professor of biology and botany, at Goucher College in Baltimore. His biggest work in science was a study of roles of color and pattern in the tropical reef fishes, which was done with the assistance of Dry Tortugas Laboratory of the Carnegie Institution in Washington, where he worked as a director from 1922 to 1937. He studied distribution and evolution of the species as well. He studied a lot of plants in places like Hawaii, Samoa Samoa, officially the Independent State of Samoa; sm, Sāmoa, and until 1997 known as Western Samoa, is a Polynesian island country consisting of two main islands (Savai'i and Upolu); two smaller, inhabited islands (Manono Island, Manono an ..., Tortugas, and the Pacific, and examining some in European and American museums. he died in 1937.

William Beebe
Charles William Beebe ( ; July 29, 1877 – June 4, 1962) was an American naturalist, ornithologist, marine biologist, entomologist, explorer, and author. He is remembered for the numerous expeditions he conducted for the New York Zoological Society, his deep dives in the Bathysphere, and his prolific scientific writing for academic and popular audiences. Born in Brooklyn, New York and raised in East Orange, New Jersey, Beebe left college before obtaining a degree to work at the then newly opened New York Zoological Park, where he was given the duty of caring for the zoo's birds. He quickly distinguished himself in his work for the zoo, first with his skill in designing habitats for its bird population, and soon also with a series of research expeditions of increasing length, including an expedition around the world to document the world's pheasants. These expeditions formed the basis for a large quantity of writing for both popular and academic audiences, including an account ...

John Tee-Van
John Tee-Van (July 6, 1897 – November 5, 1967) was an American ichthyologist and zoologist. He began his career as an apprentice zookeeper at the New York Zoological Park (now the Bronx Zoo) and ended it as its General Director. Biography Born in Brooklyn, New York son of Patrick J. Tee-Van and Wilhelmina Wehnke Tee-Van, John attended school in New York City and took courses in zoology at New York University. He began his career at the Bronx Zoo in 1911, at the age of 14, as an apprentice keeper in the Bird Department, joining the zoo after the death of his father, who had also been an employee of the zoo. Career Work with William Beebe Tee-Van left his position in the Bird Department in 1917 after Department Curator William Beebe heard that Tee-Van took night classes in architectural drafting and asked him to draw a bird bone. Beebe was so impressed with Tee-Van’s drawing that he immediately made him an assistant in his new department (which was to become the Department of T ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blenny
Blenny (from the Greek and , mucus, slime) is a common name for many types of fish, including several families of percomorph marine, brackish, and some freshwater fish sharing similar morphology and behaviour. Six families are considered "true blennies", grouped under the order Blenniiformes; its members are referred to as blenniiformids. About 151 genera and nearly 900 species have been described within the order. The order was formerly classified as a suborder of the Perciformes but the 5th Edition of ''Fishes of the World'' divided the Perciformes into a number of new orders and the Blenniiformes were placed in the percomorph clade Ovalentaria alongside the such taxa as Cichliformes, Mugiliformes and Gobiesociformes. Families The six "true blenny" families are: * Blenniidae Rafinesque, 1810 - combtooth blennies, including the sabre-toothed blennies * Chaenopsidae Gill, 1865 - pikeblennies, tubeblennies and flagblennies * Clinidae Swainson, 1839 - clinids, inclu ...

Atlantic Ocean
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.

Fish Of The Caribbean
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 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. Most f ...

Taxa Named By William Harding Longley
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
