The serpent, which has two brains but just one of every other vital organ, was born at The Pet Zone in the US city of Pittston, Pennsylvania.
In the clip, the snake can be seen writhing around as it explores its handler’s palm.
According to store manager William Pambianco, one in 10,000,000 snakes born with two heads live past two weeks.
But the small corn snake – named Gemini – has incredibly overcome those odds as it turns six weeks old tomorrow.
Both heads had been observed trying to go in different directions, but one seemed more dominant.
“Both heads eat,” William said.
“It has eaten five times – the right head three times and the left head twice, so they go back and forth.
“I’m assuming they share one stomach because one head will eat and it does seem to nourish the body.
“It has eaten five times – the right head three times and the left head twice”
“So I’m assuming it’s one stomach, one heart and all the regular organs that would be in a normal snake, but with two heads.
“And there are two brains because the heads operate differently – one tries to go one way, one tries to go the other.
“It looks like the right head is more dominant and pulls the other head where it wants to go.”
The manager went on to explain why these two-headed reptiles are so rare.
William said: “It’s about one in every 100,000 will have two heads formed.
“Most of those will die in the egg or don’t live much past the hatching period because there’s another deformity.
“Usually it’s not one deformity on its own, usually there’s also a deformity with the heart or liver or lungs too.
“But we’re fortunate enough that this snake is nearly six weeks old, it’s eaten five times and has passed waste, and we have not noticed any other abnormalities or deformities.”
And the store is even looking to the future with Gemini.
William went on to say that – should the reptile get past six to eight months – it could go on to live its full 13 to 15 year lifespan.
Two-headed snakes can be born when an embryo starts to divide into twins, but does not complete the process.
The store currently plans to keep the snake for its customers to visit.
