Hippolyte Californiensis
''Hippolyte californiensis'', the California green shrimp, is a species of shrimp in the family Hippolytidae. It is native to the eastern Pacific Ocean. It was first described in 1895 by the zoologist S.J. Holmes from Bodega Bay, California. Of the 32 or so species in the genus ''Hippolyte'', it is most closely related to '' H. obliquimanus'' and '' H. williamsi''. Description Three species of shrimp in the genus ''Hippolyte'' are known from the eastern Pacific Ocean. The California green shrimp is a very slender, green glass-like shrimp up to about in length, with females generally being larger than males. The carapace is extended forwards as a long rostrum. Distribution The California green shrimp is known from the western coast of North America where it ranges in shallow water from Bodega Bay to the Gulf of California, but is uncommon southwards from Elkhorn Slough. It inhabits calm waters, hiding by day under rocks and in cracks. Ecology The California green shrimp is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caridea
The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp. Biology Carideans are found in every kind of aquatic habitat, with the majority of species being marine. Around a quarter of the described species are found in fresh water, however, including almost all the members of the species-rich family Atyidae and the Palaemonidae subfamily Palaemoninae. They include several commercially important species, such as '' Macrobrachium rosenbergii'', and are found on every continent except Antarctica. The marine species are found at depths to , and from the tropics to the polar regions. In addition to the great vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Hippolytidae
Hippolytidae is a family of cleaner shrimp, also known as broken-back shrimp or anemone shrimp. The term "broken-back shrimp" also applies to the genus ''Hippolyte'' in particular and "cleaner shrimp" is sometimes applied exclusively to ''Lysmata amboinensis''. Taxonomy As of 2009, there were 36 genera in the family: Morphological and genetic studies have recovered the Hippolytidae as polyphyletic, prompting the recognition of Bythocariidae, Lysmatidae, Merguiidae, and Thoridae.De Grave, S, Li, C.P., Tsang L.M., Chu K.H., Chan T.-Y.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hippolyte Obliquimanus
In Classical Greek mythology, Hippolyta, or Hippolyte (; grc-gre, Ἱππολύτη ''Hippolytē'') was a daughter of Ares and Otrera, queen of the Amazons, and a sister of Antiope and Melanippe. She wore her father Ares' ''zoster'', the Greek word found in the Iliad and elsewhere meaning "war belt." Some traditional English translations have preferred the more feminine-sounding " girdle." Hippolyta figures prominently in the myths of both Heracles and Theseus. The myths about her are varied enough that they may therefore be about several different women. The name ''Hippolyta'' comes from Greek roots meaning "horse" and "let loose." Legends Ninth Labor of Heracles In the myth of Heracles, Hippolyta's belt (ζωστὴρ Ἱππολύτης) was the object of his ninth labour. He was sent to retrieve it for Admete, the daughter of King Eurystheus.Hyginus, ''Fabulae'', 30 Most versions of the myth indicate that Hippolyta was so impressed with Heracles that she gave hi ...

Carapace
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum. The carapace is calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single plate which carries the eyes, ocularium, ozopores (a pair of openings of the scent gland of Opilione ...

Rostrum (anatomy)
Rostrum (from Latin ', meaning ''beak'') is a term used in anatomy for a number of phylogenetically unrelated structures in different groups of animals. Invertebrates * In crustaceans, the rostrum is the forward extension of the carapace in front of the eyes. It is generally a rigid structure, but can be connected by a hinged joint, as seen in Leptostraca. * Among insects, the rostrum is the name for the piercing mouthparts of the order Hemiptera as well as those of the snow scorpionflies, among many others. The long snout of weevils is also called a rostrum. * Gastropod molluscs have a rostrum or proboscis. * Cephalopod molluscs have hard beak-like mouthparts referred to as the rostrum.

Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado, Fuerte, Mayo, Sinaloa, Sonora, and the Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.
