Romaleon Antennarium
''Romaleon antennarium'' (formerly ''Cancer antennarius''), commonly known as the Pacific, brown or California rock crab, is a crab of the genus '' Romaleon'' found on the western coast of North America. Description ''Romaleon antennarium'' has a fan-shaped carapace with eleven teeth to either side of the eyestalks, the widest point falling at the eighth or ninth tooth. The chelipeds are quite stout with the black tips bent downward. The antennae are long and prominent, accounting for the specific name. The dorsal surfaces of adults are uniformly red, but the ventral surface of the carapace is spotted. This species is easily confused with the red rock crab, '' Cancer productus''. They can be distinguished by the less prominent antennae, less robust claws, and lack of ventral spots on the latter. Fishery ''R. antennarium'' is harvested by sport and commercial fishermen in California, mostly from Morro Bay Morro Bay (''Morro'', Spanish for "Hill") is a seaside city in ...

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. It covers the taxonomy, ecology, and conservation of Southeast Asian fauna.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.

Contributions To Zoology
''Contributions to Zoology'' (formerly known as ''Bijdragen tot de Dierkunde'') is a scientific journal that started in 1848 as a publication of the Committee in charge of the library of the Dutch Royal Zoological Society "Natura Artis Magistra" and became integrated in the library of the University of Amsterdam in 1939. Since 2019 the journal is published by Brill publishers, Leiden. The journal has been freely available online since 1997. The current editor-in-chief is Ronald Vonk from Naturalis Biodiversity Center, Leiden. Contributions to Zoology solicits high-quality papers in all systematics-related branches of comparative zoology (including paleozoology). Preference is given to manuscripts dealing with conceptual issues and to integrative papers (e.g., ecology and biodiversity, morphology and phylogeny and character state evolution, phylogeny and historical biogeography, systematics and bioinformatics, bioinformatics and biodiversity, habitat disturbance and biogeography, e ...

Cancer (genus)
''Cancer'' is a genus of marine crabs in the family Cancridae. It includes eight extant species and three extinct species, including familiar crabs of the littoral zone, such as the European edible crab (''Cancer pagurus''), the Jonah crab (''Cancer borealis'') and the red rock crab ('' Cancer productus''). It is thought to have evolved from related genera in the Pacific Ocean in the Miocene. Description The species placed in the genus ''Cancer'' are united by the presence of a single posterolateral spine (on the edge of the carapace, towards the rear), anterolateral spines with deep fissures (on the carapace edge, towards the front), and a short extension of the carapace forward between the eyes. Their claws are typically short, with grainy or smooth, rather than spiny, keels. The carapace is typically oval, being 58%–66% as long as wide, and the eyes separated by 22%–29% of the carapace width. Species The genus ''Cancer'', as currently circumscribed, contains eight extan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...
