The Boxfish Twist

The boxfish became famous as a low-drag marvel — but the story has a catch. Later studies found its boxy body does not glide as cleanly as first claimed, and the shape actually makes the fish a bit unstable, which it fixes with constant fin corrections. So the real lesson is humbler than the legend. The boxfish still gave Mercedes a smart starting point and a brilliant armor pattern, but biology inspires — it doesn't hand you a finished blueprint.
