Believe it or not, the title of this article is not clickbait.

The exploding ants of Borneo (which include C. saundersi and a few other species) contain an impressive quantity of toxic chemicals inside mandibular gland reservoirs that have remarkably expanded to fill a large portion of the body. These ants are able to rupture their bodies, covering an attacker in the chemicals, killing both the attacker and itself.

Pretty cool.
