What Wikipedia says

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 in 1916 as "the many attempts of Nature to evolve a crab".
