Slime reduces drag: fish

Skins of fish reduce drag by being covered by a slime layer of complex proteins, polysaccharides, and bacteria.

BIOMIMICRY TAXONOMY
Summary
"Specific organisms can be targeted for specialized purposes. Slick 'no drag' hulls have been sought for centuries. The slickest surface is not a waxed or polished or Teflon surface, contrary to common belief. Using biomimicry, most fish have a clearly articulated slime layer of complex proteins, polysaccharides and bacteria. They are very fast and achieve this speed from the physical/chemical interface of water molecules with the surfaces of the bacteria and components which harbor either thinly affixed water molecules or compounds which have the appropriate hydrophilicity/hydrophobicity balance."
