What is the ten-letter name of the beetle that, when threatened or swallowed by a toad or other predator, can project (or drop, perhaps?) hot, noxious chemicals from the tip of its abdomen, accompanied by a popping sound? Beetles of this type are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini and comprise more than 500 species altogether.
