Look closer
A shark's skin is rough. So why can roughness sometimes improve flow?
Smooth sounds fast. Nature asks us to look more carefully.
The surprise
A mako shark does not wear a smooth wetsuit. Its skin is covered in microscopic, tooth-like scales called dermal denticles.
The hidden interaction
Their directional ridges meet the thin boundary layer of water beside the body. A surface is not merely a wrapper - its geometry can influence how flow behaves right at the wall.
The important warning
Roughness is not automatically better. Shape, scale, direction, speed, and conditions must work together. Copying the look without the relationship misses the design.
The idea worth keeping
Do not copy an organism's appearance. Copy the function, then test it in the real conditions.
