  • The crustacean group can be treated as a subphylum under the clade Mandibulata. (wikipedia.org)
  • Most crustaceans are free-living bottom feeders aquatic animals, but some are terrestrial (e.g. woodlice, sandhoppers), some are parasitic (e.g. (wikipedia.org)
  • Most crustaceans are aquatic, living in either marine or freshwater environments, but a few groups have adapted to life on land, such as terrestrial crabs, terrestrial hermit crabs, and woodlice. (wikipedia.org)
  • The body of a crustacean is composed of segments, which are grouped into three regions: the cephalon or head, the pereon or thorax, and the pleon or abdomen. (wikipedia.org)
  • All other classes of crustaceans have a limbless abdomen, except from a telson and caudal rami which is present in many groups. (wikipedia.org)
  • It is unclear whether the biramous condition is a derived state which evolved in crustaceans, or whether the second branch of the limb has been lost in all other groups. (wikipedia.org)
  • Those relatives are different groups of crustaceans, as Insecta is nothing less than a group of crustaceans that includes a lineage with flying forms. (peerj.com)
  • Different groups of crustaceans tend to differ in the number of structures included into the feeding process. (peerj.com)
  • The decapods or Decapoda are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crayfish, crabs, lobsters, prawns and shrimp. (absoluteastronomy.com)
  • Highly prized as seafood, lobsters are economically important, and are often one of the most profitable commodities in coastal areas they populate.Though several groups of crustaceans are known as lobsters, the clawed lobsters are most. (absoluteastronomy.com)
  • More than 7.9 million tons of crustaceans per year are harvested by fishery or farming for human consumption, consisting mostly of shrimp and prawns. (wikipedia.org)
  • It is now well accepted that the hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. (wikipedia.org)
  • The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans (oligostracans and multicrustaceans). (wikipedia.org)
  • In particular, while the taxon joining hexapods and crustaceans (the Pancrustacea) is now widely accepted among zoologists, the relationships among its basal lineages, and particularly the supposed reciprocal paraphyly of Crustacea and Hexapoda, continues to represent a challenge.

  • The scientific study of crustaceans is known as carcinology (alternatively, malacostracology, crustaceology or crustalogy), and a scientist who works in carcinology is a carcinologist. (wikipedia.org)
  • One of the most contentious issues was the identification of the closest relative to the Hexapoda, with Myriapoda and Crustacea alternatively emerging as plausible candidates. (biomedcentral.com)
  • Our study shows that regions of ambiguous alignment may provide useful phylogenetic signal when secondary structure information is used to guide the alignment procedure and provides an R implementation to the Bayesian Relative Rates test. (biomedcentral.com)
  • The number and variety of appendages in different crustaceans may be partly responsible for the group's success. (wikipedia.org)
  • Phyllopodous limbs are among the most well-known features of Branchiopoda, but it is uncertain whether the phyllopodous nature of the limbs in itself can be considered a synapomorphy for this group, because the limbs of other crustaceans, both recent and fossil, also can be characterised as at least partly phyllopodous. (bioone.org)
  • Aspects of the evolution of the branchiopod crustaceans are reviewed and discussed. (bioone.org)
  • This, together with the subsequent long anagenetic evolution along each major lineage, has considerably complicated our possibility to reconstruct their phylogenetic relationships. (biomedcentral.com)
