Brown Rockfish
The brown rockfish (''Sebastes auriculatus''), whose other names include brown seaperch, chocolate bass, brown bass and brown bomber, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is found in the northeastern Pacific Ocean. Taxonomy The brown rockfish was first formally described as ''Sebastodes auriculatus'' in 1854 by the French ichthyologist Charles Frédéric Girard with the type locality given as San Francisco, California. Some authorities place this species in the subgenus ''Auctospina''. The specific name ''auriculatus'' means "eared" thought to be an allusion to the dark spot on rear margin of operculum. Description The Brown Rockfish has a deep body which has a depth of 33% to 37% of its standard length and they typically have spines on the head which has a small terminal mouth. The overall color is reddish-brown with many dark markings, these include a dark spot on the rear upper angl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuchal
The nape is the back of the neck. In technical anatomical/medical terminology, the nape is also called the nucha (from the Medieval Latin rendering of the Arabic , "spinal marrow"). The corresponding adjective is ''nuchal'', as in the term ''nuchal rigidity'' for neck stiffness. In many mammals the nape bears a loose, non-sensitive area of skin, known as the scruff, by which a mother carries her young by her teeth, temporarily immobilizing it during transport. In the mating of cats the male will grip the female's scruff with his teeth to help immobilize her during the act, a form of pinch-induced behavioral inhibition Pinch-induced behavioural inhibition (PIBI), also called dorsal immobility, transport immobility or clipnosis, is a partially inert state which results from a gentle squeeze of the skin behind the neck. It is mostly observed among cats and allows .... Cultural connotations In traditional Japanese culture, the was one of the few areas of the body (other than f ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Bodega Bay
Bodega Bay ( es, Bahía Bodega) is a shallow, rocky inlet of the Pacific Ocean on the coast of northern California in the United States. It is approximately across and is located approximately northwest of San Francisco and west of Santa Rosa. The bay straddles the boundary between Sonoma County to the north and Marin County to the south. The bay is a marine habitat used for navigation, recreation (including swimming and surfing, especially by the Dillon Beach area), and commercial and sport fishing (including shellfish harvesting). Bodega Bay is protected on its north end from the Pacific Ocean by Bodega Head, which shelters the small Bodega Harbor and is separated from the main bay by a jetty. The San Andreas Fault runs parallel to the coastline and bisects Bodega Head, which lies on the Pacific Plate; the town is on the North American Plate. The village of Bodega Bay sits on the east side of Bodega Harbor. The bay connects on its south end to the mouth of Tomales Bay. ...

Gulf Of Alaska
The Gulf of Alaska (Tlingit: ''Yéil T'ooch’'') is an arm of the Pacific Ocean defined by the curve of the southern coast of Alaska, stretching from the Alaska Peninsula and Kodiak Island in the west to the Alexander Archipelago in the east, where Glacier Bay and the Inside Passage are found. The Gulf shoreline is a combination of forest, mountain and a number of tidewater glaciers. Alaska's largest glaciers, the Malaspina Glacier and Bering Glacier, spill out onto the coastal line along the Gulf of Alaska. The coast is heavily indented with Cook Inlet and Prince William Sound, the two largest connected bodies of water. It includes Yakutat Bay and Cross Sound. Lituya Bay (a fjord north of Cross Sound, and south of Mount Fairweather) is the site of the largest recorded tsunami in history. It serves as a sheltered anchorage for fishing boats. Ecology The Gulf of Alaska is considered a Class I, productive ecosystem with more than 300 grams of carbon per square meter per year ...

Prince William Sound
Prince William Sound (Sugpiaq: ''Suungaaciq'') is a sound of the Gulf of Alaska on the south coast of the U.S. state of Alaska. It is located on the east side of the Kenai Peninsula. Its largest port is Valdez, at the southern terminus of the Trans-Alaska Pipeline System. Other settlements on the sound, which contains numerous small islands, include Cordova and Whittier plus the Alaska native villages of Chenega and Tatitlek. History James Cook entered Prince William Sound in 1778 and initially named it Sandwich Sound, after his patron the Earl of Sandwich. Later that year, the Sound was named to honour George III's third son Prince William Henry, then aged 13 and serving as a midshipman in the Royal Navy. In 1790, the Spanish explorer Salvador Fidalgo entered the sound, naming many of its features. Some places in the sound still bear the names given by Fidalgo, as Port Valdez, Port Gravina or Cordova. The explorer landed on the actual site of Cordova and took possession of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
