Increase in hydrostatic pressure forces blood from pores
31. Middle ear senses barometric pressure: Eastern pipistrelle bat
"Bat researcher Dr. Ken Paige of the University of Illinois's Institute for Environmental Studies noted that flying insects were most common when air (barometric) pressure was low (except in heavy rain). During these conditions eastern pipistrelle...

32. Fibers reinforce hydrostatic skeletons: sunflowers
"With few exceptions, nature uses the second arrangement of fibers for her internally pressurized, water-filled cylinders. These structures (often termed 'hydrostatic skeletons' or 'hydroskeletons' as well as 'hydrostats') have helical reinforcing...
33. Turrets provide nest ventilation: leaf-cutting ants.
"Social insects construct nests that are regarded as adaptive structures, because they offer the colony inhabitants both protection and a long-term more stable microclimate (Korb 2003; Hansell 2005; Bollazzi et al. 2008). Among ants, colonies belo...

38. Chromophores protect from harmful UV: dwarf mountain pine
"Solar UV radiation is harmful to many biological systems, as well as all kind of technical applications. UV protective coatings are commonly utilised to shield many susceptible substances. In an attempt to learn from nature we demonstrate that fo...
39. Insect elytra resist shear and cracking: beetles
"Nature is replete with examples of layered-structure materials that are evolved through billions of years to provide high performance. Insect elytra (a portion of the exoskeleton) have evoked worldwide research attention and are believed to serve...
40. Large ears aid cooling: elephant
"Elephants, too, have huge ears relative to body size, and they are also used for temperature regulation. It has been shown that blood passing through the ears of an African elephant may lose as much as 9˚C of heat, a valuable cooling device in t...
