They can grow up to 10- to 12-feet-long, although Behnke said that in their natural habitat, they have been known to reach 26 feet.

"It's becoming more and more of a problem, perhaps no fault of the animal, more a fault of the human," Jorge Pino, a spokesman with the Florida Fish and Wildlife Conservation Commission, told The Associated Press. "People purchase these animals when they're small. When they grow, they either can't control them or release them."
