Performing CPR on a Turtle and Debunking Swamp Myths - David Steen

Scientists use traps to capture turtles, so they can study their numbers in swamps around the country. The issue comes when water levels suddenly change, leaving oxygen-breathing turtles trapped underwater and they'll die. But when David Steen found one such turtle, the field biologist, committed to animals and their conservation, he decided to try giving the turtle CPR. Steen explains how to perform CPR on a turtle with a thick shell. He also busts some rattlesnake myths and explains how invasive species can ruin the biodiversity of an ecosystem.
