Two heads aren't always better than one.

Especially if you're a plains garter snake, and one head decides it would rather go under a rock, while the other wants to take the high road.

Then, there's a bit of a tussle to decide which head ultimately wins.

This modern-day Medusa, a two-headed garter snake, is the newest addition at Sternberg Museum of Natural History, a snake that's actually a transplant from a homeowner's yard in Kearney, Neb.

The snake, according to Sternberg collections manager Curtis Schmidt, was found by the homeowners. They in turn contacted a professor at the University of Nebraska-Kearney, who also happens to be a friend of Schmidt's.

"He asked me if I wanted it for the museum," Schmidt said.

He quickly said yes, and the snake is now living in a terrarium at the museum, soon to be on display, either in the Discovery Room or in the lobby.

Museum officials also plan to ask the public to offer suggestions for a name for the snake.

Officially, the snake is known as being bicephalic -- having two heads.

They don't do well in the wild, typically living only for a short period of time.

It's a rare condition, but not unheard of, and often they can live in captivity.

Schmidt was able to pick up the snake Saturday.

It's too young to determine if it's a male or female, he said.
