The strange creature was found by Tugrul Metin, a 39-year-old gym teacher, on the west coast of Turkey near the city of Izmir. Metin said he was shocked when he walked over to the dolphin after he watched the lifeless mass float ashore.
"I couldn't take it in at first, I thought my eyes were playing tricks on me," Metin told the Daily Mail. "I've never even heard about a dolphin like this let alone seen one with my own eyes. I was completely shocked."
Local police moved the dolphin from the beach to a laboratory, where biologists will have the opportunity to examine the creature.
Mehmet Gokoglu, a marine biologist at Ak Deniz University, told the Turkish Times he was excited at the chance to study the mammal.
"Such a dolphin is a very rare occurrence -- similar to the occurrence of conjoined human twins," Gokoglu said.
Although rare, two-headed or conjoined animals -- like humans -- aren't unheard of. Last year, a two-headed calf was birthed by a cow in Vermont. A two-headed alligator was spotted in Tampa, Florida, earlier this summer.
