Formally known as 'yellow goo' ants because of the color of the splatter they spew after exploding themselves, the newly described Colobopsis explodens of Borneo (right) self-sacrifices itself to kill another invading ant species. Brutal!
To blow themselves up, the reddish-brown minor workers -- all sterile females -- contracted a part of their abdomens called the gaster. They clenched it so tightly that it ruptured, spewing a yellow secretion that was manufactured in the ants' jaw glands and had "a distinctive spice-like odor," according to the study.
Damn, clenching your stomach so hard it ruptures -- that's serious business. Me? Whenever I clench my stomach really hard the only thing that happens is you can see my sick abs and all the babes swoon. "There's no way you have abs." I have never even had a single ab. Sit-ups are for people who aren't comfortable in their own skin lying down.
Thanks to Cabanaz, who agrees they should really try some sort of peer mediation first.
