Zapteryx Xyster
The southern banded guitarfish (''Zapteryx xyster''), also known as the witch guitarfish, is a species of fish in the Trygonorrhinidae family found at reefs and other habitats from shallow water to a depth of 150 m in the tropical East Pacific. It ranges from Mazatlan, Mexico, to Colombia, but it likely also occurs off Ecuador and Peru. It is threatened by habitat loss. It is closely related to the more northernly distributed banded guitarfish (''Z. exasperata''). Description As the name implies, southern banded guitarfish possess a flat, depressed body form that is reminiscent of a guitar. Their anatomy resembles other members of the Elasmobranchii, elasmobranch subclass including fused pectoral wings and an asymmetrical caudal fin characteristic of rays and sharks respectively. Individuals are brown or black in color with dark bands formed by many continuous blotches. Both large and small thorns are present throughout the dorsal surface of the body, beginning at the nape and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zapteryx Exasperata
The banded guitarfish, mottled guitarfish, prickly skate or striped guitarfish (''Zapteryx exasperata'') is a species of fish in the Trygonorrhinidae family''.'' Originally ''Z. exasperata'' was placed in the Rhinobatidae family, however recent mitochondrial DNA analysis shows their placement into the new family of Trygonorrhinidae. They are found from shallow water to a depth of in the East Pacific from California, United States, to Mazatlan, Mexico, including the Gulf of California. The species has also been recorded further south (as far as Peru), but this likely involves its close relative, the southern banded guitarfish (''Z. xyster''). Characteristics Banded guitarfish have diamond-shaped bodies that, as their name suggests, resemble guitars. Their coloration is dark gray to sandy brown with characteristic black or dark brown banding along the back. They generally have large eyes with a short, rounded snout. The tail is thick from the base of the disc to its rounded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he served as president of Indiana University Bloomington, Indiana University from 1885 to 1891. Jordan was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration", asserting that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and education Jordan was born in Gainesville (town), New York, Gainesville, New York, and grew up on a farm in upstate New York. His parents made an unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, ...

Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, 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 conservation movement, 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 187 ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Johannes Peter Müller
Johannes Peter Müller (14 July 1801 – 28 April 1858) was a German physiologist, comparative anatomist, ichthyologist, and herpetologist, known not only for his discoveries but also for his ability to synthesize knowledge. The paramesonephric duct (Müllerian duct) was named in his honor. Life Early years and education Müller was born in Coblenz. He was the son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself to become a Roman Catholic Priest. During his college course in Koblenz, he devoted himself to the classics and made his own translations of Aristotle. At first, his intention was to become a priest. When he was eighteen, his love for natural science became dominant, and he turned to medicine, entering the University of Bonn in 1819. There he received his M.D. in 1822. He then studied at the University of Berlin. There, under the influence of G. W. F. Hegel and Kar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Gustav Jakob Henle
Friedrich Gustav Jakob Henle (; 9 July 1809 – 13 May 1885) was a German physician, pathologist, and anatomist. He is credited with the discovery of the loop of Henle in the kidney. His essay, "On Miasma and Contagia," was an early argument for the germ theory of disease. He was an important figure in the development of modern medicine. Biography Henle was born in Fürth, Bavaria, to Simon and Rachel Diesbach Henle (Hähnlein). He was Jewish. After studying medicine at Heidelberg and at Bonn, where he took his doctor's degree in 1832, he became prosector in anatomy to Johannes Müller at Berlin. During the six years he spent in that position he published a large amount of work, including three anatomical monographs on new species of animals and papers on the structure of the lymphatic system, the distribution of epithelium in the human body, the structure and development of the hair, and the formation of mucus and pus. He also developed a friendship with another ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
