Zoology: Secrets of the ‘uncrushable’ diabolical ironclad beetle
Lacking the ability to fly away from danger, this insect has crush-resistant exoskeletal forewings (called elytra), which means that it is able to withstand crushing and piercing strikes from predators and can survive being run over by vehicles. … David Kisailus, [UCI professor of material science and engineering] and colleagues report the structural features and material composition of the elytra, which allow the beetle to withstand forces of up to 149 newtons (approximately 39,000 times its body weight).
