The nonprofit, led by marine biologist Amber Kuehn, shared a photo of the rare sight in a Facebook post Wednesday.
"We thought we had seen it all during this very busy season on Sea Turtle Patrol!" the post read. "Yesterday on patrol during a nest inventory, this bicephalic hatchling was discovered. This mutation is more common in reptiles than in other animals but it is still very rare. As with other live hatchlings found during a nest inventory, this hatchling was released to the ocean. Good luck to Squirt and Crush!"
