Oligocottus Rubellio
The rosy sculpin (''Oligocottus rubellio'') is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. It inhabits the coastal northeastern Pacific Ocean, ranging from California (US) to Baja California. Taxonomy The rosy sculpin was first formally described in as ''Eximia rubeliio'' in 1899 by the A merican physiologist and ichthyologist Arthur White Greeley with its type locality given as Monterey, California. The specific name, ''rubellio'', means “the rosy one”, an allusion to the pale red or pink color it can show. Description The rosy sculpin has a smooth body, lacking scales or prickles. The nasal spine has a cirrus and up to 4 more cirri on the rear of the jaw. There are tufts, made up of cirri, along the dorsal fin base, the lateral line and on the head. The topmost spine on the preoperculum has between 2 and 4 points, 3 is typical. The dorsal fin contains between 7 and 9 spines and between 13 and 17 soft rays while the anal fi ...

Arthur White Greeley
Arthur White Greeley (June 13 1875 – March 15, 1904) was an American physiologist and ichthyologist. Greeley was born in Oswego, New York, the eldest of two sons of Frank Norton Greeley, a Congregational clergyman, and Anna Cheney (Buckhout) Greeley. His brother William would go on to become chief forester of the U.S. Forest Service. He graduated from Stanford University in 1898, and spent one year as a graduate student in zoology, during which he went to Alaska with the fur-seal expedition and to Brazil with the Banner-Agassiz expedition, where he made most of the biological collections. The following year he was an instructor at San Diego Normal School (now San Diego State University), leaving there to enter the University of Chicago as fellow in physiology. Two years later he took his doctorate of philosophy under Jacques Loeb with a thesis on the action of low temperatures on micro-organisms, and was then appointed Assistant Professor of Zoology at the Washington University i ...

Oligocottus
''Oligocottus'' is a genus of marine ray-finned fishes belonging to the Family (biology), family Cottidae, the typical sculpins. These sculpins are found in the northern and eastern Pacific Ocean. Taxonomy ''Oligocottus'' was first proposed as a monospecific genus in 1856 by the French biologist Charles Frédéric Girard when he described ''Oligocottus maculosus'' from Tomales Bay, San Francisco, California. The 5th edition of ''Fishes of the World'' classifies this genus within the subfamily Cottinae of the family Cottidae, however, other authors classify the genus within the subfamily Oligocottinae of the family Psychrolutidae. The genus has been found to be a monophyletic grouping with the saddleback sculpin as the more basal of the four species with the other three species creating a polytomy. Etymology ''Oligocottus'' prefixes ''oligos'', meaning "small", with ''Cottus'', the type species of the family Cottidae. This is an allusion to the small size of ''O. maculosus''. Sp ...

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrimp
Shrimp are crustaceans (a form of shellfish) with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata of the decapod order, although some crustaceans outside of this order are referred to as "shrimp". More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (abdomens), long whiskers ( antennae), and slender legs. Any small crustacean which resembles a shrimp tends to be called one. They swim forward by paddling with swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks with the tail driving them backwards very quickly. Crabs and lobsters have strong walking legs, whereas shrimp have thin, fragile legs which they use primarily for perching.Rudloe & Rudloe (2009 ...

Amphipoda
Amphipoda is an 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 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychaete
Polychaeta () is a paraphyletic class (biology), class of generally marine invertebrate, marine annelid worms, common name, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the Alitta virens, sandworm or Alitta succinea, clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe Nereus (underwater vehicle), ''Nereus'' at the bottom of the Challenger Deep, the deepes ...

Punta Baja
Punta is an Afro-indigenous dance and cultural music originating in the Caribbean Island of Saint Vincent And The Grenadines by the Garifuna people before being exiled from the island. Which is also known as Yurumei. It has African and Arawak elements which are also the characteristics of the Garifuna language. Punta is the best-known traditional dance belonging to the Garifuna community. It is also known as banguity or bunda, before the first arrival of the Garifuna people in Punta Gorda, Roatan, Honduras on April 12, 1797. The diaspora of Garifuna people, commonly called the "Garifuna Nation", dates back to the amalgamation of West African slaves and the Arawak and Carib Amerindians. Punta is used to reaffirm and express the struggle felt by the indigenous population's common heritage through cultural art forms, such as dance and music, and to highlight their strong sense of endurance as well as reconnecting back to the ancestors of the Garifuna people.

Fort Bragg, California
Fort Bragg, officially the City of Fort Bragg, is a city along the Pacific Coast of California along Shoreline Highway in Mendocino County. The city is west of Willits, at an elevation of . Its population was 6,983 at the 2020 census. Fort Bragg is a tourist destination because of its views of the Pacific Ocean. Among its notable points of interest are Glass Beach and the California Western Railroad (popularly known as the "Skunk Train"). A California Historical Landmark, Fort Bragg was founded in 1857 prior to the American Civil War as a military garrison rather than a fortification. It was named after army officer Braxton Bragg, who at the time had served the U.S. in the Mexican–American War (and would later serve in the Confederate Army during the Civil War). The city was later incorporated in 1889. History The area now known as Fort Bragg was home to Native Americans since before Western expansion, most of whom belong to the Pomo tribe.

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries 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. Simply put, 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 (sharks and rays), as well as some other fishes.

Caudal 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 to lu ...
