We usually think of invertebrates as a frog’s favourite meal. But in this episode we explore the times when the tables turn and frogs fall victim to mighty invertebrates. Except for the Accra snake-necked frog, they have an ingenious way of avoiding invertebrate conflict. Species of the Bi-week features a double-bill of tree frogs.

There is no denying that chameleons are fascinating lizards, but why should the tree-dwelling ones get all the credit? In this episode we unearth some recent discoveries concerning Brookesia and friends, as well as taking a look at the world's shortest lived tetrapod, Labord's chameleon.
