Plagiogrammus
The crisscross prickleback (''Plagiogrammus hopkinsii'') is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies. It is the only species in the monotypic genus ''Plagiogrammus''. This fish is found in the eastern Pacific Ocean off California. Taxonomy The crisscross prickleback was first formally described in 1894 by the American ichthyologist Tarleton Hoffman Bean with its type locality given as Monterey, California. Bean placed his new species in a new monotypic genus, ''Plagiogrammus''. This taxon is classified within the subfamily Stichaeinae of the Zoarcoid family Stichaeidae. Etymology The crisscross pickleback's generic name, is a compound of ''plagio'', meaning "slanting", and ''grammus'', meaning line. Bean did not explain what this alluded to but it may refer to the upper lateral line “curves very slightly” over the pectoral fin. The specific name honors Timothy Hopkins, who founded the Seaside Laboratory a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stichaeidae
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean. Taxonomy Stichaeidae was first proposed as a family in 1864 by the American zoologist Theodore Gill, although he called it the Stichaeoidae. The 5th edition of ''Fishes of the World'' classifies this family within the suborder Zoarcoidei, within the order Scorpaeniformes. Other authorities classify this family in the infraorder Zoarcales wihin the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes renders that taxon non monophyletic. ''Fishes of the World'' mentions six subfamilies but does not assign genera to the subfamilies while other authorities split the Cebidichthyidae, Opisthocentridae, Lumpenidae and Neozoarcidae from the Sitchaeidae as valid families. The genera which are classified within the fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stichaeinae
Stichaeinae is a subfamily of marine ray-finned fishes, Taxonomy (biology), classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans. Taxonomy Stichaeinae contains the type taxon of the family Stichaeidae, the Arctic shanny (''Stichaeus punctatus''), and the name is based on Theodore Gill’s 1864 name for the family. The name of the subfamily comes from that of its type genus ''Stichaeus'', which means “set in a row”, which may be an allusion to the row of black spots on the dorsal fin, dorsal fins of the species in that genus. Genera Stichaeinae contains the following genera: ''Dinogunellus'' Solomon Herzenstein, Herzenstein, 1890 is treated as a vaild genus by ''Catalog of Fishes'' but ''Fishbase'' does not and treats the 3 species classified within it as belonging to the genus ''Stichaeus''. Characteristics Stichaeinae pricklebacks are less elongated in shape than most of the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hopkins Marine Station
Hopkins Marine Station is the marine laboratory of Stanford University. It is located ninety miles south of the university's main campus, in Pacific Grove, California (United States) on the Monterey Peninsula, adjacent to the Monterey Bay Aquarium. It is home to ten research laboratories and a fluctuating population of graduate and undergraduate students. It has also been used for archaeological exploration, including of the Chinese-American fishing village that existed on the site before burning down in 1906. History Hopkins Marine Station was founded in 1892, making it the oldest marine laboratory on the US Pacific Coast, and the second-oldest in the US, after the Marine Biological Laboratory in Woods Hole, Massachusetts. It was originally named the Hopkins Seaside Laboratory and located on what is now called Lovers Point. In 1917, the laboratory was moved to its current location on Mussel/China/Cabrillo Point, and given its current name: Hopkins Marine Station of Stanford Un ...

Mollusca
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropod ... [...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] |
Mysida
Mysida is an order (biology), order of small, shrimp-like crustaceans in the malacostracan superorder Peracarida. Their common name opossum shrimps stems from the presence of a Brood pouch (Peracarida), brood pouch or "marsupium" in females. The fact that the Crustacean larvae, larvae are reared in this pouch and are not Motility, free-swimming characterises the order. The mysid's head bears a pair of stalked eyes and two pairs of antennae. The thorax consists of eight segments each bearing branching limbs, the whole concealed beneath a protective carapace and the abdomen has six segments and usually further small limbs. Mysids are found throughout the world in both shallow and deep marine waters where they can be Benthos, benthic or pelagic, but they are also important in some fresh water and brackish water, brackish ecosystems. Many benthic species make Diel vertical migration, daily vertical migrations into higher parts of the water column. Mysids are filter feeders, omnivores ...

San Nicolas Island
San Nicolas Island (Spanish: ''Isla de San Nicolás''; Tongva: ''Haraasnga'') is the most remote of the Channel Islands, off of Southern California, 61 miles (98 km) from the nearest point on the mainland coast. It is part of Ventura County. The 14,562 acre (58.93 km2 or 22.753 sq mi) island is currently controlled by the United States Navy and is used as a weapons testing and training facility, served by Naval Outlying Landing Field San Nicolas Island. The uninhabited island is defined by the United States Census Bureau as Block Group 9, Census Tract 36.04 of Ventura County, California. The Nicoleño Native American tribe inhabited the island until 1835. As of the 2000 U.S. Census, the island has since remained officially uninhabited, though the census estimates that at least 200 military and civilian personnel live on the island at any given time. The island has a small airport, though the runway is the second longest in Ventura County (slightly behind the one a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...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.
