There were frogs, toads, salamanders, other amphibians, turtles, lizards, snakes, and alligators. We learned the most important difference between reptiles and amphibians is that amphibians go through metamorphasis whereas reptiles do not.
Here are a few pictures to enjoy. (There were several more animals than shown here including the tiger salamander, several snakes, stinkpot turtle, various toads, skink lizard, and probably some others that I somehow missed getting pictures of them.) All are native to Arkansas except where noted.
