Sheila Patek: Measuring the fastest animal on earth
http://www.ted.com UC Berkeley biologist Sheila Patek gives a wide-ranging talk on the effort to measure the hyperfast movements of peacock mantis shrimp heels using high-speed video cameras recording at 20,000 frames per second. She and her team slowed down the movements of these amazing animals and showed they had the fastest known feeding strike in the animal kingdom. (In 2006, Patek's team announced an even faster animal part: the mandible of the trap-jaw ant.)
