A two-headed turtle has hatched at the San Antonio Zoo. Name: Thelma and Louise. The female Texas cooter arrived June 18 and will go on display tomorrow at the zoo's Friedrich Aquarium. The turtle appears healthy and is able to swim and walk, and experts at the zoo don't foresee any health problems. The San Antonio facility is no stranger to two-headed reptiles: The facility was home to a two-headed Texas rat snake named Janus from 1978 until the creature's death in 1995.
