barnacle. n. 1. (Animals) any of various marine crustaceans of the subclass Cirripedia that, as adults, live attached to rocks, ship bottoms, etc. They have feathery food-catching cirri protruding from a hard shell. See acorn barnacle, goose barnacle.
Because mating systems in barnacles exist on an evolutionary continuum (Fig. 3), data on variation among individuals of the same species may help to illuminate some of the larger scale evolutionary forces that select for different mating systems.ndrodioecy in barnacles has proved difficult to study because it is most prevalent in deep water scalpellids. More complete knowledge of the natural history and reproductive biology of these species would improve our understanding of the evolution of androdioecy and dioecy.
