Victorian zoologist Louis Agassiz, “nothing more than a little shrimp-like animal, standing on its head in a limestone house and kicking food into its mouth. Barnacles have the longest penis in the animal kingdom, in proportion to their body length. They are abundant on the seashore, docks, and pilings.
