- Well, hydro/aero-dynamically fish and birds have a lot in common! Fish's
- fins and birds' wings have an aerodynamic shape that is best suited for
- their purpose. The main difference being the gravitation that a bird has
- to struggle with; therefore aren't birds' wings symmetrical in cross-
- section. Fish's fins are vertical because they have to turn the corner
- quickly and not so quickly up and down.
