Photo by joelsartore | Meet the Pac-Man frog. Chacoan horned frogs, like this one at Sedgwick County Zoo in Kansas, are known for trying to consume prey larger than themselves. Thanks to a strong bite and a row of teeth along their upper jaw, they can immobilize larger prey, but unfortunately, those teeth mean they can’t release prey once it is caught. Oversize prey can often become a choking hazard, sometimes leading to the frog’s death. To see more species featured in the Photo Ark, follow joelsartore. #PhotoArk sedgwickcountyzoo
