Biologists have used 3D video to capture a rattlesnake striking a kangaroo rat for the first time. Technological advances in high-speed cameras have given scientists the chance to examine the strike performance of rattlesnakes under natural conditions. Studying the predator-prey relationship between the two animals has enabled researchers to examine the way the two species can adapt during evolution. Research leader Dr Timothy Higham, associate professor of biology at the University of California, Riverside, said: "Predator-prey interactions are naturally variable - much more so than we would ever observe in a controlled laboratory setting. "Technology is now allowing us to understand what defines successful capture and evasion under natural conditions.
