Natantia
Natantia (Boas, 1880) is an obsolete taxon of decapod crustaceans, comprising those families that move predominantly by swimming – the shrimp (comprising Caridea and Procarididea), prawns (Dendrobranchiata) and boxer shrimp. The remaining Decapoda were placed in the Reptantia, and consisted of crabs, lobsters and other large animals that move chiefly by walking along the bottom. The division between Natantia and Reptantia was replaced in 1963, when Martin Burkenroad erected the suborder Pleocyemata for those animals that brood their eggs on the pleopods, leaving Dendrobranchiata for the prawns. Under this system, Natantia is a paraphyletic group Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In con .... Burkenroad's primary division of Decapoda into Dendrobranchiata and Pleocyemata has ...

Shrimp
A shrimp (: shrimp (American English, US) or shrimps (British English, UK)) is a crustacean with an elongated body and a primarily Aquatic locomotion, swimming mode of locomotion – typically Decapods belonging to the Caridea or Dendrobranchiata, although some Shrimp#Non-decapods, crustaceans outside of this order are also referred to as "shrimp". Any small crustacean may also be referred to as "shrimp", regardless of resemblance. More narrow definitions may be restricted to Caridea, to smaller species of either of the aforementioned groups, or only the Marine life, marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (Abdomen#Arthropoda, abdomens), long whiskers (Antenna (biology), antennae), and slender, Biramous, biramous legs. They swim forward by paddling the swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks wit ...

Reptantia
Reptantia is a clade of decapod crustaceans named in 1880 which includes lobsters, crabs and many other well-known crustaceans. Classification In older classifications, Reptantia was one of the two suborders of Decapoda alongside Natantia, with Reptantia containing the walking forms, and Natantia containing the swimming forms (prawns, shrimp and boxer shrimp). However, in 1963 Martin Burkenroad found Natantia to be paraphyletic and invalid, and instead split Decapoda into the two suborders of Dendrobranchiata (prawns) and Pleocyemata. Pleocyemata contains all the members of the Reptantia (including crabs, lobsters, crayfish, and others), as well as the Stenopodidea ("boxer shrimp"), and Caridea (true shrimp). Reptantia remains a valid monophyletic grouping, but is now no longer ranked as a suborder. Anatomy The name Reptantia means "those that walk", and contains those decapods whose primary mode of locomotion is to walk along a surface using the pereiopods rather than ...

Dendrobranchiata
Dendrobranchiata is a suborder of Decapoda, decapods, commonly known as prawns. There are 540 extant species in seven families, and a fossil record extending back to the Devonian. They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills and by the fact that they do not brood their eggs, but release them directly into the water. They may reach a length of over and a mass of , and are widely shrimp fishery, fished and shrimp farm, farmed for human consumption. Shrimp and prawns While Dendrobranchiata and Caridea belong to different Order (biology), suborders of Decapoda, they are very similar in appearance, and in many contexts such as commercial farming and Fishery, fisheries, they are both often referred to as "shrimp" and "prawn" interchangeably. In the United Kingdom, Australia and some other Commonwealth of Nations, Commonwealth, the word "prawn" is used almost exclusively, while the opposite is the case in North America. The term ...

Caridea
The Caridea, commonly known as caridean shrimp or true shrimp, from the Greek word καρίς, καρίδος (karís, karídos, “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 water, fresh and seawater, 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 ...

Martin Burkenroad
Martin David Burkenroad (March 20, 1910 – January 12, 1986) was an American marine biologist. He specialized in decapod crustaceans and fisheries science. Biography Burkenroad was born in New Orleans in 1910 as the only child of coffee importer David Burkenroad and his artist wife Flora Salinger. His family contained many eccentrics, and Martin was similarly labeled "headstrong". He entered Tulane University in 1926, but although he published his first papers during that time, his studies ended when he was "'encouraged' to leave" in 1929. He then began working for the Carnegie Marine Biological Laboratory in the Dry Tortugas, before joining the Louisiana Department of Conservation in 1931, where he studied the local shrimp fishery. After brief spells at several museums, he joined Yale University under the guidance of A. E. Parr. Burkenroad spent many productive years at Yale, where the usual time limit for research for a dissertation was permanently waived for him, but he n ...

Pleocyemata
Pleocyemata is a suborder of decapod crustaceans, erected by Martin Burkenroad in 1963. Burkenroad's classification replaced the earlier sub-orders of Natantia and Reptantia with the monophyletic groups Dendrobranchiata (prawns) and Pleocyemata. Pleocyemata contains all the members of the Reptantia (including crabs, lobsters, crayfish, and others), as well as the Stenopodidea (which contains the so-called "boxer shrimp" or "barber-pole shrimp"), and Caridea, which contains the true shrimp. Anatomy All members of the Pleocyemata are united by a number of features, the most important of which is that the fertilised eggs are incubated by the female, and remain stuck to the pleopods (swimming legs) until the zoea larvae are ready to hatch. It is this characteristic that gives the group its name. Pleocyemata also possess a lamellar gill structure as opposed to the branches found in the Dendrobranchiata. Systematics The cladogram below shows Pleocyemata as the sister clade to D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obsolete
Obsolescence is the process of becoming antiquated, out of date, old-fashioned, no longer in general use, or no longer useful, or the condition of being in such a state. When used in a biological sense, it means imperfect or rudimentary when compared with the corresponding part of other organisms. The international standard IEC 62402:2019 Obsolescence Management defines obsolescence as the "transition from available to unavailable from the manufacturer in accordance with the original specification". Obsolescence frequently occurs because a replacement has become available that has, in sum, more advantages compared to the disadvantages incurred by maintaining or repairing the original. Obsolete also refers to something that is already disused or discarded, or antiquated. Typically, obsolescence is preceded by a gradual decline in popularity. Consequences Driven by rapid technological changes, new components are developed and launched on the market with increasing speed. The resul ...

Paraphyletic Group
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor except ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoologische Mededelingen
''Zoologische Mededelingen'' was a peer-reviewed open access scientific journal publishing papers and monographs on animal systematics. The publisher was the National Museum of Natural History Naturalis in the Netherlands. The first issue appeared in 1915, as the official journal of Naturalis' predecessor, the Rijks Museum van Natuurlijke Historie. Earlier, the museum published ''Muséum d'Histoire Naturelle des Pays-Bas'' (volumes I–XIV, 1862–1908) and ''Notes from the Leyden Museum'' (volumes I-XXXVI, 1879–1914), which mainly covered the fauna of the Netherlands and the former Dutch colonies. ''Zoologische Mededelingen'' was indexed in ''The Zoological Record'' and ''BIOSIS BIOSIS Previews is an English-language, bibliographic database service, with abstracts and citation indexing. It is part of ''Clarivate Analytics Web of Science'' suite. BIOSIS Previews indexes data from 1926 to the present. BIOSIS Previews i ...''. A complete backlist of published volumes is pres ...

Stenopus Hispidus
''Stenopus hispidus'' is a shrimp-like decapod crustacean belonging to the infraorder Stenopodidea. Common names include coral banded shrimp and banded cleaner shrimp. Distribution ''Stenopus hispidus'' has a pan-tropical distribution, extending into some temperate areas. It is found in the western Atlantic Ocean from Canada to Brazil, including the Gulf of Mexico. In Australia, it is found as far south as Sydney and it also occurs around New Zealand. Description ''Stenopus hispidus'' reaches a total length of , and has striking colouration. The ground colour is transparent, but the carapace, abdomen and the large third pereiopod are all banded red and white. The antennae and other pereiopods are white. The abdomen, carapace and third pereiopods are covered in spines. ''Stenopus hispidus'' has the ability to detect individuals of its species. This trait is uncommon in invertebrates and is most likely explained through chemical signals. Ecology ''Stenopus hispidus'' lives be ...

Heterocarpus Ensifer
''Heterocarpus ensifer'' is a species of deep-water Caridea, shrimp. The nominate subspecies is found in the Atlantic Ocean from Spain and Madeira to Angola and from North Carolina to the Gulf of Mexico and Caribbean Sea; other subspecies occur in the Pacific Ocean and around the Philippines and Indonesia. Despite being one of the most abundant shrimp in some areas, its biology is still poorly known. These deep water crustaceans are most copious between 300 and 400m. Their distribution demonstrates an ability to adapt well to distinct environments. It is generally found at depths of .

Penaeus Monodon
''Penaeus monodon'', commonly known as the giant tiger prawn, Asian tiger shrimp, black tiger shrimp, and other names, is a marine crustacean that is widely reared for food. Taxonomy ''Penaeus monodon'' was species description, first described by Johan Christian Fabricius in 1798. That name was overlooked until 1949, when Lipke Holthuis clarified to which species it referred. Holthuis also showed that ''P. monodon'' had to be the type species of the genus ''Penaeus''. Description Females can reach about long, but are typically long and weigh ; males are slightly smaller at long and weighing . The carapace and abdomen are transversely banded with alternative red and white. The antennae are grayish brown. Brown pereiopods and pleopods are present with fringing setae in red. Distribution Its natural distribution is the Indo-Pacific, ranging from the eastern coast of Africa and the Arabian Peninsula, as far as Southeast Asia, the Pacific Ocean, and northern Australia.
