But Why?: Why Do Turtles Need Shells? Why Do Frogs Hop?

Why do turtles need shells and why do they move so slowly?

Why do frogs hop? Why are frogs green? Are colorful frogs poisonous? Why do frogs inflate their throats? What are some of the biggest threats to amphibians and reptiles? We wade into a Vermont pond with herpetologists Jim Andrews and Kate Kelly! We also get a preview of the new Earth Rangers podcast.
