Inflatable Resilient Structures
Mound facilitates gas exchangemound-building termites
The structure of above-ground macrotermite mounds facilitates gas exchange in the below-ground nest using internal air currents driven by solar heat.
Bark keeps surface cool under the suntrees
Bark of trees keeps surface cool by minimizing absorption of solar light and maximizing thermal emission
Cactus hides from the sunmescal cactus
The shoot of the mescal cactus adapts to seasonal water availability via dehydration-induced shrinking below the desert floor, and hydration-induced swelling to reemerge after rainfall.
Shape shades and enhances heat radiationcactus
Cacti stay cool by having ribs that provide shade and enhance heat radiation.
Blubber absorbs heatbottlenose dolphin
The blubber of the bottlenose dolphin absorbs heat by acting as a phase change material

Intricate silica architecture survives forcesdiatoms
Silica-based skeletons of microscopic diatoms offer significant resistance to impact forces due to symmetry, pores, nanospheres, and ribs.
Vines repair themselvespipevine
Stems of pipevines repair fissures and ruptures in their strengthening tissues by parenchyma cells from surrounding tissues swelling into the fissure to seal it.
Shell protects from heatdesert snail
The shell of some desert snails helps them survive extreme heat using light reflectance and architecturally-derived, insulating layers of air.
Arches provide structural supporttermites
The nests of termites gain structural support for chambers, ventilation shafts, and insulating cavities because arches are the main architectural element.
