Gorongosa has a rich diversity of frogs, and few are as beautiful and unusual as the Rubber frog (Phrynomantis bifasciatus). These mostly nocturnal animals can sometimes be seen after heavy rains around termite mounds or climbing tree trunks, where they hunt termites, ants, and other tiny insects. Thanks to a unique structure of their skull and tongue they can catch prey that is positioned to the side or even slightly behind them, all without having to turn their head.
Rubber frogs are not very good jumpers, but they don’t need to be – their skin contains toxins that most predators will be glad to avoid. They advertise this toxic warning with contrasting, black and orange coloration. Rubber frog’s skin secretion may cause skin irritation in humans, and thus it is wise not to touch them.
