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 ...

Oligocottus Snyderi
The fluffy sculpin (''Oligocottus snyderi'') or Lizard Fish is a fish species in the sculpin family Cottidae. It inhabits the coastal northwestern Pacific Ocean, ranging from Kodiak, Alaska to Baja California (Mexico). Individuals reach up to in length, and are commonly found in tidepools, often associated with algae. Description The fluffy sculpin grows to a length of about . The dorsal fin has 7 to 9 spines and 17 to 20 soft rays, and the anal fin has no spines but 12 to 15 soft rays. In the male, the first anal ray is enlarged and the first three rays are separated from the others. The body is smooth and lacks scales. There is a short spine on the snout with a cirrus beside it, and tufts of cirri on the top of the head, along the lateral line and at the base of the dorsal fin. The colour of this fish is variable, being anything from green to pink or reddish-brown. Distribution and habitat The fluffy sculpin is native to the western coast of North America, its range extending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocottus Maculosus
The tidepool sculpin (''Oligocottus maculosus'') is a fish species in the sculpin family Cottidae that ranges from the Bering Sea to southern California. Individuals reach up to in length and are common in tidepools. Description The tidepool sculpin grows to a length of about and has a large head, tapering body, and spiny fins. It has a single pre-opercular spine and tufts of cirri on the top of the head but not on the body below the dorsal fin as the fluffy sculpin (''Oligocottus snyderi'') does. It varies considerably in colour, is often marbled in grey, brown and white, but may be reddish or greenish and can change colour rapidly so as to camouflage itself. Distribution and habitat The tidepool sculpin is found in the northeastern Pacific Ocean from the Bering Sea to southern California. Its depth range is from the intertidal zone down to about . It is tolerant of both brackish water and normal seawater. It is found higher up the shore and is more tolerant of warmer water ...

Oligocottus Rimensis
The saddleback sculpin (''Oligocottus rimensis'') is a species of fish in the sculpin family Cottidae The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera.Kane, E. A. and T. E. Higham. (2012)Life in the flow lane: differences in pectoral fin morphology .... It is known to inhabit the North American shore of the Pacific Ocean. It is a very understudied fish with limited knowledge of behavioral patterns, lifecycle and reproduction. Taxonomy The saddleback sculpin was originally described by Arthur White Greeley as ''Rusciculus Rimensis'', /sup> and later classified as ''Stelgidonotus latifrons'' by Gilbert and Thompson in 1905 /sup>. The subfamily Oligocottinae was introduced in 1926 using morphological similarities between the Oligocottus type as well as several additional characteristics. These included: three soft pelvic rays, a moderate number of dorsal spines, preopercular spi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 fin is ...

Psychrolutidae
The fish family Psychrolutidae (commonly known as blobfishes, flathead sculpins, or tadpole sculpins) contains over 35 recognized species in 8 genera. This family consists of bottom-dwelling marine sculpins shaped like tadpoles, with large heads and bodies that taper back into small, flat tails. The skin is loosely attached and movable, and the layer underneath it is gelatinous. The eyes are placed high on the head, focused forward closer to the tip of the snout. Members of the family generally have large, leaf-like pectoral fins and lack scales, although some species are covered with soft spines. This is important to the species as the depths in which they live are highly pressurized and they are ambush/opportunistic/foraging predators that do not expend energy unless they are forced to. The blobfish has a short, broad tongue and conical teeth that are slightly recurved and are arranged in bands in irregular rows along the premaxillaries; canines are completely absent. Teeth are ...

Cottidae
The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera.Kane, E. A. and T. E. Higham. (2012)Life in the flow lane: differences in pectoral fin morphology suggest transitions in station-holding demand across species of marine sculpin. ''Zoology'' (Jena) 115(4), 223–32. They are referred to simply as cottids to avoid confusion with sculpins of other families. Cottids are distributed worldwide, especially in boreal and colder temperate climates. The center of diversity is the northern Pacific Ocean. Species occupy many types of aquatic habitats, including marine and fresh waters, and deep and shallow zones. A large number occur in near-shore marine habitat types, such as kelp forests and shallow reefs. They can be found in estuaries and in bodies of fresh water. Most cottids are small fish, under in length. The earliest fossil remains of cottids are otoliths potentially assignable to ...

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. The Gulf of Alaska is considered a Class I, productive ecosystem with more than 300 grams of carbon per square meter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bering Sea
The Bering Sea ( , ; rus, Бе́рингово мо́ре, r=Béringovo móre, p=ˈbʲerʲɪnɡəvə ˈmorʲe) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and the Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named after Vitus Bering, a Denmark, Danish-born Russia, Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Berin ...

Sea Of Okhotsk
The Sea of Okhotsk; Historically also known as , or as ; ) is a marginal sea of the western Pacific Ocean. It is located between Russia's Kamchatka Peninsula on the east, the Kuril Islands on the southeast, Japan's island of Hokkaido on the south, the island of Sakhalin along the west, and a stretch of eastern Siberian coast along the west and north. Its northeast corner is the Shelikhov Gulf. The sea is named for the port of Okhotsk, itself named for the Okhota River. Geography The Sea of Okhotsk covers an area of , with a mean depth of and a maximum depth of . It is connected to the Sea of Japan on either side of Sakhalin: on the west through the Sakhalin Gulf and the Gulf of Tartary; on the south through the La Pérouse Strait. In winter, navigation on the Sea of Okhotsk is impeded by ice floes. Ice floes form due to the large amount of freshwater from the Amur River, lowering the salinity of upper levels, often raising the freezing point of the sea surface. The ...
