When millipedes are picked up, their defense strategy is to curl up into a coil. Most millipedes also have paired glands in their legs that secrete a toxic combination of chemicals, including cyanide, which effectively deters most predators. But it does not dissuade the black lemur, the stoner of the animal kingdom.

After the lemur bites the millipede, it sprays its toxic secretion, which the lemur then rubs all over its fur. Research suggests that there is a practical purpose to this: the benzoquinone secretion functions as a natural pesticide and wards off malaria-carrying mosquitos. The secretion also acts as a narcotic, which causes the lemur to salivate profusely and enter a state of intoxication.
