Liparis Mucosus
''Liparis mucosus'', or the slimy snailfish, is a fish from the genus '' Liparis''. The fish can be found from intertidal areas to 15 meters in depth. In general, they are not found in tide pools. The slimy snailfish ranges in the Northeastern Pacific Ocean from Sitka, Alaska to southern British Columbia, Canada as well as to Baja California, Mexico. It grows to 2.8–5 inches. Description The slimy snailfish's color varies from gray to brownish to red, and occasionally the fish has dark stripes. Its dorsal fin has a lobe at the front. The fish's gill slit extends to the front of the upper pectoral fin rays.

William Orville Ayres
William Orville Ayres (September 11, 1817 – April 30, 1887) was an American physician and ichthyologist. Born in Connecticut, he studied to become a doctor at Yale University School of Medicine. Life and career Ayers, the son of Jared and Dinah (Benedict) Ayres, was born in New Canaan, Conn, September 11, 1817. He graduated from Yale College in 1837. For fifteen years after graduation he was employed as a teacher as follows in Berlin, Conn. (1837–38), Miller's Place, L. I. (1838–41), East Hartford, Conn. (1842–44), Sag Harbor, L. I. (1844–47), and Boston, Mass (1845–52). He began the study of medicine in Boston, and in 1854 received the degree of M.D. from Yale College. He then removed to San Francisco, Cal., where he remained for nearly twenty years, engaged in practice. He also served as Professor of the Theory and Practice of Medicine in the Toland Medical College in that city. He removed to Chicago shortly before the great fire of 1871, in which he suffere ...

Liparis (fish)
''Liparis'' is a large genus of snailfish from the northern hemisphere. They are very common in temperate and cold waters. Chernova (2008) has proposed that the genus should be subdivided into five subgenera: ''Liparis'', ''Neoliparis'', ''Lycocara'', ''Careliparis'', and ''Lyoliparis''. The generic name is from Ancient Greek λιπαρός (''liparos'', "oily"). Species There are currently 60 recognized species in this genus: * '' Liparis adiastolus'' Stein, C. E. Bond & Misitano, 2003 * ''Liparis agassizii'' Putnam, 1874 * '' Liparis alboventer'' ( Krasyukova, 1984) * '' Liparis antarcticus'' Putnam, 1874 * '' Liparis atlanticus'' ( D. S.

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...

Gill Slit
Gill slits are individual openings to gills, i.e., multiple gill arches, which lack a single outer cover. Such gills are characteristic of cartilaginous fish such as sharks and rays, as well as deep-branching vertebrates such as lampreys. In contrast, bony fishes have a single outer bony gill covering called an operculum. Most sharks and rays have five pairs of gill slits, but a few species have 6 or 7 pairs. Shark gill slits lie in a row behind the head. The anterior edge of a gill slit is motile, moving outward to allow water to exit, but closing to prevent reverse flow. A modified slit, called a spiracle, lies just behind the eye, which assists the shark with taking in water during respiration and plays a major role in bottom–dwelling sharks. Spiracles are reduced or missing in active pelagic sharks. While the shark is moving, water passes through the mouth and over the gills in a process known as "ram ventilation". While at rest, most sharks pump water over their gills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectoral Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod ...

Taxa Named By William Orville Ayres
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] |
