Biomimicry is when people draw inspiration from nature while creating.
The McLaren design team solved a pesky aero wind noise issue they were having with their P1 hypercar by utilizing a feature of a sailfish’s biology. The car’s designer Frank Stephenson took note of how sailfish manages turbulent flow as it swims and applied it onto the support arm for the car’s mirrors.

For reference, the P1 sells for around 2 million.
