Air-trapping coating for ships submarinesCollege of Engineering, Ohio State University
Coating to reduce drag, increase bouyancy
Slime reduces dragfish
Skins of fish reduce drag by being covered by a slime layer of complex proteins, polysaccharides, and bacteria.
Shark paintFraunhofer Institute for Manufacturing Engineering and Applied Materials Research IFAM
Coating that reduces drag and UV damage, and has other properties
Scales manipulate flowShortfin mako shark
Scales on sharks influence drag and thrust during swimming by manipulating fluid flow next to the body.
Eco-Clad anti-fouling paintLuritek
Coating to reduce drag, prevent fouling
Whiskers reduce dragharbor seals
The highly sensitive whiskers of harbor seals reduce vortex-induced vibrations during swimming due to their undulating surface structure.
Fur decreases water turbulenceseals
The fur of seals may help them swim efficiently by maintaining laminar flow.
Scales form protective layerbony fish
Some bony fish protect themselves with a layer of smooth-edged cycloid scales made of bone.
Body shape reduces frictiondolphin
The body of the dolphin has low friction in water by having an optimal length to diameter ratio.
