Arrow Goby
The arrow goby (''Clevelandia ios'') is a species of goby native to marine and brackish waters of the Pacific coast of North America from British Columbia to Baja California. This species grows to a length of SL, though most do not exceed TL. This fish can also be found displayed in public aquaria. This species is the only known member of its genus. Description The arrow goby is a small, pale grey, translucent fish which grows to in length. It has two dorsal fins; the first is the shorter and has 4-5 spines while the dorsal fin has 15-17 soft fin rays. The anal fin is about equal in length to the second dorsal fin and has 14-17 fin rays. Like other gobies, the caudal fin is rounded and the pectoral fins form a cone which the goby uses to prop the anterior part of its body above the substrate. Its scales are minute, and the mouth extends beyond to the eye. The dorsal fins have short horizontal stripes and the body is pale brownish-grey in colour with darker mottling. Dis ...

Anal 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 ...

Staghorn Sculpin
The Pacific staghorn sculpin (''Leptocottus armatus'') is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in the eastern Pacific Ocean. It is the only species in the monospecific genus ''Lepidocottus''. Taxonomy The Pacific staghorn sculpin was first formally described in 1854 by the French biologist Charles Frédéric Girard with its type locality given as San Francisco in California. Girard placed it in a new monospecific genus, ''Leptocottus''. The 5th edition of ''Fishes of the World'' classifies the genus ''Leptocottus'' within the subfamily Cottinae of the family Cottidae, Etymology The Pacific staghorn sculpin's genus name, ''Leptocottus'', is a combination of ''leptos'', meaning "slender", and '' Cottus''. The specific name ''armatus'' means "armed", a reference to the large and sharp spines on the preoperculum. Description Pacific staghorn sculpins are slender fish, with a wide, large, highly flattened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sebastes
''Sebastes'' is a genus of marine ray-finned fish belonging to the subfamily Sebastinae part of the family Scorpaenidae, most of which have the common name of rockfish. A few are called ocean perch, sea perch or redfish instead. They are found in the Atlantic and Pacific Oceans. Taxonomy ''Sebastes'' was first described as a genus in 1829 by the French zoologist Georges Cuvier, the Dutch ichthyologist Pieter Bleeker designated ''Perca norvegica'', which may have been originally described by the Norwegian zoologist Peter Ascanius in 1772, as the type species in 1876. The genus is the type genus of both the tribe Sebastini and the subfamily Sebastinae, although some authorities treat these as the subfamily Sebastinae and the family Sebastidae, separating the Sebastidae as a distinct family from the Scorpaenidae. but other authorities place it in the Perciformes in the suborder Scorpaenoidei. Some authorities subdivide this large genus into subgenera as follows: * ''Sebastes'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tintinnid
Tintinnids are ciliates of the choreotrich order Tintinnida, distinguished by vase-shaped shells, the name deriving from a Latin source meaning a small tinkling bell, that are called'' loricae'', which are mostly protein but may incorporate minute pieces of minerals. Fossil record Fossils resembling tintinnid loricas in shape and size, Calpionellids, appear as early as the Ordovician period but are formed of calcite and as no extant ciliate taxa forms calcite shells they are unlikely to be tintinnids and probably not ciliates at all. Fossils which can be reliably related to extant tintinnids (e.g. fossils of agglutinated lorica) are in the fossil record during the Jurassic but do not become abundant until the Cretaceous. Tintinnids are an important part of the fossil record because of the rarity with which most other ciliates become preserved under the conditions of the marine environment. The loricae of some tintinnids are easily preserved, giving them a relatively good fossi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few other organi ...

Diatom
A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of ...

Urechis Caupo
''Urechis caupo'' is a species of spoon worm in the family Urechidae, commonly known as the innkeeper echiuran, the fat innkeeper worm (because the tunnels often contain other animals), the innkeeper worm, or the penis fish. It is found in shallow water on the west coast of North America, between southern Oregon and Baja California, where it forms a U-shaped burrow in the sediment and feeds on plankton using a mucus net. Description ''Urechis caupo'' is a plump, unsegmented, cylindrical pink worm growing to a length of up to , with being a more typical length. There are a pair of setae (bristles) on the ventral surface at the anterior end, and a distinctive ring of about ten setae around the anus at the posterior end. The proboscis is short. Distribution and habitat Shallow water in the northeastern Pacific Ocean is the habitat of ''U. caupo''; its range extends from southern Oregon to northern Baja California. It lives in a burrow in muddy sand in the lower intertidal and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Rivers Inlet
Rivers Inlet is a fjord in the Central Coast region of the Canadian province of British Columbia, its entrance off Fitz Hugh Sound, about southwest of the community of Bella Coola and about north of the northern tip of Vancouver Island and the western entrance of the Queen Charlotte Strait. Rivers Inlet was a major fishing area with huge salmon runs. At one time it had the second largest sockeye salmon run only to the Fraser River. A total of 19 Canneries were built in the area starting late in the 1890's. Three canneries remained as they dotted the shorelines until their closure by consolidation through the monopoly of companies, and the consolidation around large centralized ice plants in the 1950s. Name origin Rivers Inlet was named by George Vancouver for George Pitt the 1st Baron Rivers (1721-1803). Two of his men, Peter Puget and Joseph Whidbey, first charted it in 1792. Geography The inlet is about in length from its head at the community of Rivers Inlet, which was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
