Stomach burn: toads vomit bombardier beetles which trigger explosions in the gut

The Bombardier Beetle Packs a Hot Machine Gun

Many beetles have defense mechanisms which involves foul chemicals squirting from their abdomens, but bombardier beetles have taken it to the next level. Researchers from MIT, the University of Arizona, and Brookhaven National Laboratory wanted to see how it works, so they studied the bombardier beetle and figured it out. The research is published in Science.
