9. The Bombardier Beetle – Projectile Chemicals
The African bombardier beetle protects itself by “firing” on its predators. The beetle stores two chemicals hydrogen peroxide and a hydroquinone, in separate reservoirs in its abdomen. When threatened, one chamber empties into another, causing both chemicals to mix. With the reaction bubbling in its gut, the beetle can aim the explosive spray in any direction, up, down even between its legs, with laser precision.
The chemical mix causes the formation of benzoquinones and boiling water (from the rapid oxidation of hydrogen peroxide). The highly corrosive chemical product formed has been found to stain human skin for up to three weeks. The bug is also able to ‘rapid-fire’ so that it sprays in a series of up to 70 pulses, at about 500 pulses per second! With its temperature measured at 100O C, the weapon has proven effective against all pests, small or large.
