Liparis Gibbus
''Liparis gibbus'', the polka-dot snailfish, variegated snailfish or dusky snailfish, is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes. This fish is found in Arctic waters. Juveniles of the species have been found to be biofluorescent. Taxonomy ''Liparis gibbus'' was first formally described by Tarleton Hoffman Bean in 1881 with its type locality given as Unalaska on Unalaska Island in the Aleutian Islands. The specific name ''gibbus'' means "humped" referring to the elevated nape and crown. Description ''Liparis gibbus'' is mainly brown with white fins and black sprinkled around the body. The body is wide at the front becoming laterally compressed from the to the rear of the origin of the anal fin. The depth of the body at the level of the pectoral disk averages 22.7% of the standard length. It grows to a maximum of in total length. Distribution and habitat ''Liparis gibbus'' lives in the demersal zone at a depth from 0 to in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarleton Hoffman Bean
Tarleton Hoffman Bean (October 8, 1846 – December 28, 1916) was an American ichthyologist. Biography and education Tarleton Hoffman Bean was born to George Bean and Mary Smith Bean in Bainbridge, Pennsylvania, on October 8, 1846. He attended State Normal School at nearby Millersport, Pennsylvania, graduating in 1866. He received an M.D. degree from Columbian University, now George Washington University, Washington, DC, 1876. In 1883, he was awarded an M.S. degree from the Indiana University on the basis of his professional accomplishments, although he did not attend classes there. He married Laurette H. van Hook, daughter of John Welsh VanHook, a local Washington businessman, in 1878 in Washington, DC. They had one daughter, Caroline van Hook Bean (born in Washington on November 16, 1879), a noted artist who later married Bernardus Blommers, Jr. His brother, Barton Appler Bean, also became an ichthyologist and worked under him at the National Museum.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...

Fish Of The Atlantic Ocean
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 ...

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.

Biodiversity Heritage Library
The Biodiversity Heritage Library (BHL) is the world’s largest open-access digital library for biodiversity literature and archives. BHL operates as a worldwide consortium of natural history, botanical, research, and national libraries working together to address this challenge by digitizing the natural history literature held in their collections and making it freely available for open access as part of a global "biodiversity community". The BHL consortium works with the international taxonomic community, publishers, bioinformaticians, and information technology professionals to develop tools and services to facilitate greater access, interoperability, and reuse of content and data. BHL provides a range of services, data exports, and APIs to allow users to download content, harvest source data files, and reuse materials for research purposes. Through taxonomic intelligence tools developed by Global Names Architecture, BHL indexes the taxonomic names throughout the collection, al ...

Amphipoda
Amphipoda () is an order (biology), order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods () range in size from and are mostly detritivores or scavengers. There are more than 10,700 amphipod species currently recognized. They are mostly marine animals, but are found in almost all aquatic environments. Some 2,250 species live in fresh water, and the order also includes the terrestrial Talitridae, sandhoppers such as ''Talitrus saltator'' and ''Arcitalitrus sylvaticus''. Etymology and names The name ''Amphipoda'' comes, via Neo-Latin ', from the Greek language, Greek root (linguistics), roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among Angling, anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''.

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...
