Why most fish has scales, does the shape of the scales morph? Does it change the fluid flow properties?
The placoid scales in sharks were well studied since demonstrated able to reduce the drag. Of course several different scales exist.
Have a look to this paper Article Bionic Research on Fish Scales for Drag Reduction
Dear Prof. Denaro,
This is very interesting, thank you so much for your suggestion, I am looking into it.
Regards,
