Pinnotheres Paralatissimus
''Pinnotheres'' is a genus of crabs, including the pea crab. Many species formerly in ''Pinnotheres'' have been placed in new genera, such as ''Zaops ostreus'' (formerly ''P. ostreus''), the oyster crab and ''Nepinnotheres novaezelandiae'' (formerly ''P.'' ''novaezelandiae)'', the New Zealand pea crab. The species currently recognised in the genus ''Pinnotheres'' are: References Pinnotheroidea {{Eubrachyura-stub ...

Pinnotheres Pisum
The pea crab, ''Pinnotheres pisum'', is a small crab in the family Pinnotheridae that lives as a parasite in oysters, clams, mussels, and other species of bivalves. Etymology ''Pinnotheres'' is Greek language, Greek for "guard of ''Pinna (bivalve), Pinna''" and ''pisum'' is Latin for a pea, in reference to the shape of the crab. Description Pea crabs are small crustaceans about the size of a pea or dime, with a "smooth dorsal surface of the carapace, or upper exoskeleton". The exoskeleton of males is hard and circular and has eyes and antenna (biology), antennae extending from their fronts, and the chelipeds are more robust in males than in females, which have more elongated chelipeds. The bodies of the female pea crabs are often translucency, translucent and show the inner organs and gonads as yellow and red, with the males being a "more yellowish-grey with patches of brown". Ecology The relationship between the pea crab and its host is one of parasitism, rather than commens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Augustin Guillaume Bosc
Louis Augustin Guillaume Bosc (or Louis-Augustin Bosc d'Antic) (29 January 1759 – 10 July 1828) was a French botanist, invertebrate zoologist, and entomologist. Biography Bosc was born in Paris, the son of Paul Bosc d’Antic, a medical doctor and chemist. He studied at Dijon, where he was the pupil of botanist Jean-François Durande and chemist Louis-Bernard Guyton-Morveau. Being unable to become an artilleryman, he worked initially for the office of the Controller-General of Finances, controller general and then for the comptroller of the postal service. In time he took courses in botany under Antoine-Laurent de Jussieu and met botanist René Louiche Desfontaines, René Desfontaines and naturalist Pierre Marie Auguste Broussonet. He also took up with Jean-Marie Roland, vicomte de la Platière, Jean Marie Roland and Madame Roland and formed a lasting relationship with Danish entomologist Johan Christian Fabricius. While working for the postal service he carried out work on natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Crab
Crabs are decapod crustaceans of the infraorder Brachyura (meaning "short tailed" in Greek language, Greek), which typically have a very short projecting tail-like abdomen#Arthropoda, abdomen, usually hidden entirely under the Thorax (arthropod anatomy), thorax. Their exoskeleton is often Sclerotization, thickened and hard. They generally have Arthropod leg, five pairs of legs, and they have "Pincers (tool), pincers" or "claws" on the ends of the frontmost pair, scientifically termed the ''chelae''. They are present in all the world's oceans, Freshwater crab, in freshwater, and Terrestrial crab, on land, often hiding themselves in small crevices or burrowing into sediment. Crabs are omnivores, feeding on a variety of food, including a significant proportion of Algae eater, algae, as well as Detritivore, detritus and other invertebrates. Crab meat, Crabs are widely consumed by humans as food, with over 1.5 million tonnes Crab fisheries, caught annually. True crabs first appeared ...

Oyster Crab
The oyster crab (''Zaops ostreus'') is a small, whitish or translucent crab in the family Pinnotheridae. Description and habitat Oyster crabs are small in size, typically measuring around 1 to 2 centimeters in width. They have a flattened body shape with a round carapace (shell) and relatively short legs. Their coloration can vary but often includes shades of brown, gray, or green, helping them blend in with their surroundings. Male oyster crabs are often smaller than females. * Oyster crabs are commonly found inhabiting oyster beds and other shellfish habitats in coastal regions. * They are often associated with bivalve mollusks, particularly oysters, with which they often have a parasitic relationship. Oyster crabs primarily inhabit oyster beds, which are found in coastal waters. These beds serve as vital ecosystems for many species of ''Zaops''. The structure of oyster beds provides a complex habitat that offers food, shelter, and breeding grounds for a diverse range of o ...

Raffles Bulletin Of Zoology
''The Raffles Bulletin of Zoology'' is a peer-reviewed open-access scientific journal published by the Lee Kong Chian Natural History Museum at the National University of Singapore. Overview It covers the taxonomy, ecology, and conservation of Southeast Asian fauna Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and '' funga'', respectively. Flora, fauna, funga and other forms of life are collectively .... Supplements are published as and when funding permits and may cover topics that extend beyond the normal scope of the journal depending on the targets of the funding agency. It was established as the ''Bulletin of the Raffles Museum'' in 1928 and renamed ''Bulletin of the National Museum of Singapore'' in 1961, before obtaining its current title in 1971.

New Zealand Pea Crab
The New Zealand pea crab (''Nepinnotheres novaezelandiae''), is a species of small, parasitic crab that lives most commonly inside New Zealand green-lipped mussels. Adult females are about the size and shape of a pea, while adult males are smaller and flatter. Adult New Zealand pea crabs are completely reliant on their host mussel for shelter and food, which it steals from the mussel's gills. The New Zealand pea crab is found throughout New Zealand and can infect up to 70% of natural populations. These crabs are of concern to green-lipped mussel aquaculture because they reduce the size and growth of mussels, although infected mussels can be harvested and consumed. Taxonomy This species was first described and named by Henri Filhol in 1885 as ''Pinnotheres'' ''novae-zelandiae'' and in 1901 as ''Pinnotheres schauinslandi'' (a junior synonym) by H. Lenz. It was later assigned to the genus ''Nepinnotheres''. Description Adult female New Zealand pea crabs have a soft-shelled exos ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive catalogue and list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as th ...
