Bumps and grooves protect surfacedesert scorpion
The surface of the desert scorpion resists erosion by sand due to bumps and grooves that decrease flow.
Back resists wear and teardesert scorpion
The exoskeleton of the desert scorpion resists wear due to multiple coupling effects of surface morphology, material, and flexibility.

Acoustic systems 'echolocate'
Underhairs provide insulationMerino sheep
The wool of Merino sheep forms an insulating layer via underhair that creates hundreds of trapped air pockets.
Fur absorbs infrared radiationpolar bear
Guard hairs on the polar bear prevent heat loss by absorbing heat in the form of infrared radiation.
Small leaves buffer ambient temperaturesacred datura
Small leaves of sacred datura plants buffer ambient thermal variation more efficiently than large leaves due to a smaller boundary layer, allowing higher amounts of transpiration.
Spicules are rigid structural materialssponges
The spicules of sponges are rigid structural materials due to their mineralized composition.
Stems resist bucklingplants
The stems of many plants resist buckling using low-density foam cores.
