Never mess with bombardier beetles! The beetles are famous for their explosive way of defending themselves. If threatened by predators, the beetles eject a 100°C hot chemical spray from their anus which is accompanied by a popping sound. For toads, beetles are usually a tasty snack. But bombardier beetles know how to fight back, even from the inside of a toad’s stomach. By releasing their boiling hot spray, toads are taught a painful lesson and made to regurgitate the feisty beetle.
