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 a diamond shape body that resembles a guitar, which is where the guitarfish's common name is from. Coloration is dark gray to sandy brown with black or dark brown banding along its back, corresponding to the banded part of the common name. They generally have large eyes with a short, rounded snout. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zapteryx Xyster
The southern banded guitarfish (''Zapteryx xyster''), also known as the witch guitarfish, is a species of fish in the Rhinobatidae family found at reefs and other habitats from shallow water to a depth of 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 Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... It is closely related to the more northernly distributed banded guitarfish (''Z. exasperata'').

Rajiformes
Rajiformes is one of the four orders in the superorder Batoidea, flattened cartilaginous fishes related to sharks. Rajiforms are distinguished by the presence of greatly enlarged pectoral fins, which reach as far forward as the sides of the head, with a generally flattened body. The undulatory pectoral fin motion diagnostic to this taxon is known as rajiform locomotion. The eyes and spiracles are located on the upper surface of the head and the gill slits are on the underside of the body. Most species give birth to live young, although some lay eggs enclosed in a horny capsule ("mermaid's purse"). Characteristics Rajoids typically have a dorsoventrally flattened body. The snout is slender and pointed and the wide mouth, often covered with a fleshy nasal flap, is on the underside of the head. The eyes and well-developed spiracles are located on the top of the head. In most species, the spiracles are large and are the main means of drawing water in for respiration. There is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chondrichthyes
Chondrichthyes (; ) is a class that contains the cartilaginous fishes that have skeletons primarily composed of cartilage. They can be contrasted with the Osteichthyes or ''bony fishes'', which have skeletons primarily composed of bone tissue. Chondrichthyes are jawed vertebrates with paired fins, paired nares, scales, and a heart with its chambers in series. Extant chondrichthyes range in size from the 10 cm (3.9 in) finless sleeper ray to the 10 m (32 ft) whale shark. The class is divided into two subclasses: Elasmobranchii ( sharks, rays, skates, and sawfish) and Holocephali (chimaeras, sometimes called ghost sharks, which are sometimes separated into their own class). Within the infraphylum Gnathostomata, cartilaginous fishes are distinct from all other jawed vertebrates. Anatomy Skeleton The skeleton is cartilaginous. The notochord is gradually replaced by a vertebral column during development, except in Holocephali, where the notochord stays intact. In some d ...

Taxa Named By David Starr Jordan
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chordata
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cephalochordates. These CS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barton Warren Evermann
Barton Warren Evermann (October 24, 1853 – September 27, 1932) was an American ichthyologist. Early life and education Evermann was born in Monroe County, Iowa in 1853. His family moved to Indiana while he was still a child and it was there that he grew up, completed his education, and married. Evermann graduated from Indiana University in 1886. Career For 10 years, he served as teacher and superintendent of schools in Indiana and California. While teaching in Carroll County, Indiana Evermann met fellow teacher Meadie Hawkins. They married on October 24, 1875 and had a son, Toxaway Bronte (born 1879) and a daughter, Edith (born). He was professor of biology at the Indiana State University in Terre Haute from 1886 to 1891. He lectured at Stanford University in 1893–1894, at Cornell University in 1900–1903, and at Yale University in 1903–1906. In the early 20th century, as director of the California Academy of Sciences in San Francisco, he promoted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
