It’s often said that Turkey is an excellent destination for beach goers, but this is… probably not what they had in mind. The Daily Mail reports that a bizarre two-headed dolphin was found on a beach in Izmir on Turkey’s western coast.

The strange corpse was allegedly found Monday by school gym teacher Tugrul Metin.

“I couldn’t take it in at first – I thought my eyes were playing tricks on me – I’ve never even heard about a dolphin like this let alone seen one with my own eyes – I was completely shocked,” he said.

The dolphin is on the smaller side, just over three feet in length. It’s believed to be young, only about a year old, with two distinct heads tapering down into one tail/torso. It’s unclear how the animal would have survived as long as it did. Because the eyes and one of the blowholes on one head were not fully developed, its possible that only one of the two “twins” survived.

After the discovery, Metin phoned local police, who came to transport the remains to a laboratory at Akdeniz University, where it will be studied. Marine Biologist Mehmet Gokoglu said that such an occurrence is rare, on par with finding conjoined human twins.

Conjoined twins are indeed rare in humans, with occurrences estimated between 1 in 50,000 births to 1 in 200,000 births. Even with modern technology, separating conjoined twins is a risky endeavor, often resulting in death for one or both individuals.
