Animals that start with F

F is a good letter for animals that do something physically improbable. The firefly turns nearly all the energy it uses into light with almost no waste heat, which is better than any bulb or LED humans have built. The frilled lizard bluffs predators with a disc of skin wider than its own body, and the frog, the flamingo and the fox round out the page.

5 animals in the library start with F, from the firefly to the frog. Most of them live in Africa and Asia.
