But bombardier beetles are the only ones that “heat it up and spray it,” Attygalle says.

During daylight hours, hundreds of bombardier beetles of multiple species will congregate together to more effectively ward off any predators not afraid of a lone beetle's toxic spray.

Last year’s winner, a feral Australian dog called the desert dingo, defeated a Malaysian pit viper, a “solar powered” sea slug, and the bombardier beetle, which squirts its enemies with a caustic, boiling-hot liquid.

The bombardier beetle can spray its hot brew of toxic chemicals even after bring swallowed, to force a predator into vomiting it back out.

Toads have been observed vomiting bombardier beetles after eating them, but no one knew exactly why, or how long the beetles survived after their brush with digestion.
