Visitors to Rostock Zoo are in for a rare treat – they can now view the spectacle of a snake with two heads.
The rattlesnake was put on show in an enclosure in the zoo’s monkey house on Wednesday, although It was born in June 2015 and is already 65cm long and around 65 grams in weight.
“The snake eats independently and catches food with both heads, but only eats with
one,” curator Antje Zimmermann said.
As well as two heads, the snake also has two air and food passages which join further inside its body. In every other respect the animal only has one organ.
“This is a biological rarity which is very occasionally seen,” Zimmerman said.
The reason for the phenomenon is that the fertilized egg only splits partially.
She added: “Depending on where the process stops, the result can be two heads, as with our snake.”
