The sight of two suffocating turtles, on their backs with fins tied up, horrified tourists on Little Corn Island, Nicaragua. Thanks to their quick thinking, the animals were returned safely to sea. A video posted on YouTube Monday shows tourists rescuing two loggerhead turtles, each weighing about 250 pounds. Chris Skone-Roberts, a professional rescue diver and former paramedic, first spotted the reptiles. When he tried to douse them with water, a woman angrily pulled him off—claiming they were hers. It’s presumed that once the turtles suffocated to death, she would have sold their meat on the black market.
