Silverspotted Sculpin
''Blepsias cirrhosus'', the silverspotted sculpin, is a species of sculpin belonging to the subfamily Hemitripterinae of the Family (biology), family Agonidae. This species is found the northern Pacific Ocean from the Sea of Japan and Alaska to San Miguel Island off southern California. Taxonomy ''Blepsias cirrhosus'' was first formally Species description, described as ''Trachinus cirrhosus'' by the German naturalist Peter Simon Pallas with they type locality given as "America; port of Avacha Bay, Avacha, southeastern Kamchatka; Penzhinskaya Bay, Okhotsk Sea". In 1829 Georges Cuvier proposed the monospecific genus ''Blepsias'' for ''T. cirrhosus'' so it is the type species of that genus. The Specific name (zoology), specific name ''cirrhosus'' means "curled" or "bearing tendrils", an allusion to the elongated, whiskery Barbel (anatomy), barbels on the snout and chin.

Theodore Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C. Fellow members frequently mocked him for his vanity. He was president of the American Associati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blepsias
''Blepsias'' is a genus of marine ray-finned fishes belonging to the family Agonidae, the poachers and related fishes. These fishes are found in the coastal northern Pacific Ocean from Japan to California. Taxonomy ''Blepsias'' was first proposed as a genus by the French zoologist Georges Cuvier with ''Trachinus cirrhosus'', which had originally been described in 1814 by Peter Simon Pallas from Kamchatka, as the type species. The genus is included in the subfamily Hemitripterinae of the family Agonidae. Cuvier used a Greek name for a fish, as was his habit, for the name of the new genus. Species The recognized species in this genus are: * '' Blepsias bilobus'' G. Cuvier, 1829 (crested sculpin) * '' Blepsias cirrhosus'' (Pallas, 1814) (silverspotted sculpin) Characteristics ''Blepsias'' has a spiny preoperculum, a compressed head, with armoured cheeks and palatine teeth. The large pectoral fins have the lower rays separate from the fin membrane. There are fleshy flaps which han ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scorpaeniform
The Scorpaeniformes are a diverse order of ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320. They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay: a backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the pre operculum, to which it is connected in most species. Scorpaeniform fishes are carnivorous, mostly feeding on crustaceans and on smaller fish. Most species live on the sea bottom in relatively shallow waters, although species are known from deep water, from the midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral and caudal fins. Most species are less than in length, but the full size range of the order varies from the velvetfishes belonging to the family Aploactin ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
