Carcinisation (American English: carcinization) is a form of convergent evolution in which non-crab crustaceans evolve a crab-like body plan. The term was introduced into evolutionary biology by Lancelot Alexander Borradaile, who described it as "the many attempts of Nature to evolve a crab".[2] It was stated by L. A. Borradaile in 1916 that:[3] … the phenomenon which may be called "carcinization" … consists essentially in a reduction of the abdomen of a macrurous crustacean, together with a depression and broadening of its cephalothorax, so that the animal assumes the general habit of body of a crab Keiler et al., 2017 defines a carcinised morphology as follows:[4] An important and visually evident marker of difference between true crabs and carcinised Anomura is the number of leg pairs. While Brachyura (true) crabs have four pairs of legs used for locomotion, Anomura possess one much smaller set and therefore three sets of walking legs. Carcinisation is believed to have occurred inde
