EtymologyEdit

From Ancient Greek καρκίνος (karkínos) + -ization.

NounEdit

carcinization (uncountable)

  1. The evolution of decapod crustaceans into true crab-like forms.
    • 1916, Borradaile, L.A., “British Antarctic ("Terra Nova") Expedition, 1910, Natural History Report”, in Zoology:
      Crustacea. Part II. Porcellanopagurus: An instance of carcinization.
    • 1997, Patsy A. McLaughlin & Rafael Lemaitre, “Carcinization in the anomura – fact or fiction? I. Evidence from adult morphology”, in Contributions to Zoology[1], volume 67, number 2, pages 79–123:
      Presumably, to become a "true crab" requires that a reptant decapod undergo carcinization (Borradaile, 1916) or brachyurization (Stevcic, 1971). Although the two terms appear here to be synonymous, we believe that not all authors who have employed "carcinization" or "brachyurization" have had quite the same phenomenon in mind. For example, Martin & Abele (1986) defined carcinization as the reduction and folding of the abdomen beneath the thorax, whereas Sluys (1992) used carcinization to mean the evolution of a crab-like appearance as in lithodids. To Blackstone (1989) hermit crabs became carcinized through broadening of the carapace and reduced shell-inhabiting. In this first component we address anomuran carcinization only from the perspective of adult morphology.
    • 2010, Alexandra Hiller, Carlos Antonio Viviana & Bernd Werding, “Hypercarcinisation: an evolutionary novelty in the commensal porcellanid Allopetrolisthes spinifrons (Crustacea: Decapoda: Porcellanidae)”, in Nauplius[2], volume 18, number 1 (PDF), pages 95–102:
      Porcellanids are, after brachyuran crabs, the most successful decapod group to achieve a crab-like body form through carcinisation. Unlike brachyurans, porcellanids retained the ability to swim by flapping their abdomen, armed with a well developed tail fan. Here, we present an exceptional case of carcinisation
