Ribbit...Ribbit. In this BrainPOP UK movie Tim and Moby teach you the history and biology of amphibians. You’ll be introduced to the various types of amphibians - frogs, toads, salamanders, and newts – and see how much they can differ in their body shapes and lifestyles. Find out the difference between anurans, urodeles and caecilians and the metamorphosis of a tadpole to a frog. Discover why amphibians hold a special place in vertebrate history and find out how they manage to spend their lives in two very different types of environments. Of course, you won’t learn how to catch flies like a frog, - you’re on your own with that one!
