Adaptive, sensory building skins
Tightly packed stems insulate against cold
The stems of cushion plants protect from the cold via tight packing.
Down feathers insulateking eider
The down feathers of eider ducks provide insulation due to lack of barbules and ability to fluff.
Feather structure insulatesCanada goose
Down feathers of geese insulate through special architecture.
Feather parts reattachbirds
Feather filaments of birds connect to each other with interlocking hooks.
Nanostructures help transmit lightfirefly
Nanostructures on the cuticle of the firefly's abdomen help transmit bioluminescent light efficiently because they perfectly match the wavelength of light being emitted.
