A third litter of aquatic caecilians was born at the Tennessee Aquarium over the weekend. This time senior herpetologist Bill Hughes got great shots of their gills. These organs detach from the caecilians shortly after the animals reach the surface for their first breath of air. Hughes says this exhibit is really fun to watch right now. "It's constantly in motion," Hughes said. "The baby caecilians, adults and Surinam toads are swimming around non-stop. I could watch this one tank all day long."
