Glow-in-the-dark millipede says stay away?

Upon reading the article, there were five specific facts that stuck out to me most.

1. Scientists believe they have only discovered about 10 percent of all millipede species.
2.Millipedes often display bright colors or excrete toxic fluids to turn away predators.
3.According to the experiment, the Grasshopper mouse is one of the most likely predators of millipedes.
4.All millipedes are vegetarians.
5.Bioluminescence has never been used as these scientists hypothesize the Motyxia millipedes do.

The experiment shows clear signs of the classic scientific method -- there is a hypothesis (The Motyxia millepedes use bioluminescence to turn away predators), there is a control (the millipedes used in the experiment) and a variable (The percentage of millipedes preyed upon).  Afterwords, using their observations from the experiment (which was leaving various millipedes out at night, some glowing and some painted over) they formed a conclusion -- that the Motyxia millipedes did, indeed use bioluminescence to turn away predators.
