Abstract excerpt
The precise dependence of barnacle leg form on flow suggests the wave-swept environment imposes strong selection on suspension feeding limbs. I conducted three experiments to determine the mechanism, age dependence, and response time of cirrus variation in the acorn barnacle Balanus glandula. (1) To test whether cirrus variation arises via genetic or environmental mechanisms, I transplanted juvenile barnacles...
