Conservationists were shocked this week when they discovered a two-headed sea turtle. The mutant hatchling was uncovered during a nest inventory on Hilton Head Island in South Carolina. According to experts, the anomaly, though rare, is likely a naturally occurring genetic mutation. "Some people are thinking radiation in the water, but it's not like that, it just happens in nature periodically," said Amber Kuehn, manager of Sea Turtle Patrol Hilton Head Island. The two-headed hatchling was released into the ocean.
