The San Antonio Zoo welcomed a very special arrival to their aquarium: a two-headed (bicephalic) Texas River Cooter named Thelma and Louise! Thelma and Louise were part of a quartet of Texas Cooters hatched at the zoo on June 18 that made their public debut on June 25.
Craig Pelke, Curator of Reptiles, Amphibians, and Aquatics, notes that while this is uncommon, it is not unheard of in both the wild and captive populations. Bicephalic animals are actually twins that did not separate, resulting in two or more heads on one animal. Bicephaly occurs most commonly with snakes and turtles, without any accompanying health issues. Pelke said, “At this time, Thelma and Louise are doing well on exhibit and eating with both heads!”
The San Antonio Zoo is no stranger to two-headed reptiles. A two-headed Texas rat snake named Janus lived there from 1978 until it passed away in 1995. Visitors can see the Cooter hatchlings in the Friedrich Aquarium located inside the zoo.
