vodka: If shark skin is so awesome then why to dolphins, killer whales, etc have (relatively) smooth skin?


Sharks have been around for a very long time, while marine mammals are relative newcomers to the water. Give them another hundred million years and maybe they'll evolve something comparable.

Shark skin is just scales and scales are found on all sorts of prehistoric creatures, land and sea based.  Did scales develop specifically because they were more aerodynamic or are they just a modification of body armor?

I'll go for the latter, since aerodynamics don't mean much for aquatic animals.

Microtexturing the surface of the paint seems like a good idea until you have to fly the plane on a hot summer's day and a swarm of gnats decide to microtexture the surface of the paint with their own guts.

I doubt this technology will ever justify its own cost in the real world.

Science has known about this for 30 years, and just now it's being put to use in commercial aircraft? Thanks, Obama.
