The captivating video shows a two-headed snake attacking two mice at the same time.

Reptile expert Brian Barczyk filmed the mutated serpent, named Ben and Jerry, eating two mice and hish video has since gone viral.

He shared it to his fans on Instagram, saying: “So my two-headed snake Ben and Jerry are both eating right now. They don’t always eat at the same time actually, in this case both of them are eating each side.”

The brown and yellow snake is seen swallowing the baby mice slowly but, as it only has one digestive system, some viewers asked if it would choke on the food.

One loyal fan commented: “If you watch his vlog he mentions one of them, Jerry I think, won’t take food unless Ben is already eating and for the most part Ben does all the eating but he tried to get Jerry involved too.”

Another wrote: “That is crazy! Can’t wait to go back to Michigan and check out the place!” A third asked: “Somebody mind explaining how does a two-headed snake come about…how does this mutation even happen?”

The snake has a condition called bicephaly, and it occurs from the incomplete splitting of an embryo. Interestingly, Ben and Jerry, are one of only an estimated 10,000 snakes with the condition.

Most snakes with this condition do not survive for very ʟᴏɴɢ, but Ben and Jerry appear to be an exception. Barczyk explained that ‘99.9% of two-headed animals never see their first birthday, but once they survive to adulthood, which Ben and Jerry are, they usually live a full life.

Barczyk says that he expects the animal to live between 20 and 25 years, and explained that they can eat separately but share the same digestive system.

Apparently Barczyk, who works at a reptile zoo in Michigan in the US, bought the snake from a friend. “I had to beg him for half a year until he sold me,” Barczyk said.

“We have about 10 one-of-a-kind animals [in the Reptarium] including Ben and Jerry, also a two headed turtle, and several one-of-a-kind albino and other colour mutations.”
