We quantified the hydrodynamics of the rocky intertidal stalked barnacle Capitulum mitella from the nauplius II to cyprid stage and examined how kinematics and size increases affect its swimming performance. Cyprids beat their appendages in a metachronal wave to swim faster, The nauplius for is maintained through three further stages of growth and moulting, resulting after 10-14 days in a stage VI nauplius.
