Classic ambush predators like crocs and snakes use camouflage and speed to capture their prey - sometimes faster than the blink of an eye. How do they do it? To find out, Dr. Brady Barr goes head-to-head with some of the most dangerous ambush predators on the planet. Hell trigger their strikes and film them on high-speed video. Then hell slow down those strikes, calculate exactly how fast they come at him, and deconstruct their movements to learn the biomechanics of how these ambush predators strike to kill. Brady will compare the strikes of animals like the rattlesnake, crocs, cheetahs, the slingjaw wrasse, and the mantis shrimp, and then hell perform cutting-edge reaction-time tests to find out if he stands a chance of avoiding the strike of an ambush killer.
