A two-headed turtle born at the San Antonio Zoo last month is so popular it's joined Facebook.

"Thelma and Louise" have their own page on the social networking site, and are at 2,500 followers and counting as of Monday morning.

The turtle, barely larger than the size of a quarter at birth, eats and swims like all the other turtles.

Its two heads -- named after the characters in the 1991 Oscar-winning film -- even get along, zoo officials told The Associated Press.

The turtle hatched on June 18 and is on display at the zoo's Friedrich Aquarium.
