"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!"

According to the Island Packet, Hilton Head Island's Sea Turtle Patrol, a volunteer group that monitors the reptiles, came across a hatchling with two heads this week in South Carolina.

The nonprofit, led by marine biologist Amber Kuehn, shared a photo of the rare sight in a Facebook post Wednesday.

Kuehn said the mutation is most likely genetic and not caused by environmental factors, the Island Packet reported.
