Glow in the dark millipede response

Facts I learned:
1)there are 12,000 discovered types of millipedes, and 100,000 types are thought to exist
2)millipedes are unable to see because of their many years of living underground
3)grasshopper mice are the most common predators of millipedes
4)millipedes are vegitarian and most often eat decaying plant material
5)bioluminescence is most commonly used by animals to attract mates or to attract prey

Evidence they used scientific method:
The scientists that conducted the experiment on Motyxia millipedes used the scientific method because they first asked a question, which is why do Motyxia millipedes glow in the dark.  They then did research and found relevant information about biolumiscence in other animals, defense mechanisms of other millipedes, and other information about millipedes, which led them to make their hypothesis that Motyxia millipedes use bioluminesce as a defense mechanism.  They then conducted an experiment to test their hypothesis, in which they placed non-glowing millipedes and glowing millipedes in a measured area, and waited to see if they would be attacked by predators.  They then gathered their results the next day, concluded that Motyxia millipedes do in fact glow as a defense mechanism, and then wrote the paper Bioluminescent aposematism in millipedes to communicate their results.

Glow in the Dark Millipede

The artice, Glow-In-The-Dark Millipede Says 'Stay Away', was very surprising to me because it does not seem to make sense that a millipede would use bioluminescence as a defense.  This makes an insect easier to see in the dark by predators.  Most other animals that I have heard of, such as camelions, use their colors to blend in with their surroundings so that predators cannot see them.  This seems like a more effective defense.  I think that the scientists that conducted the experiment may not be valuing one aspect of the millipede's defense, that "When they are disturbed, they ooze toxic cyanide and other foul-tasting chemicals from small pores running along the sides of their bodies as a defense mechanism."  This seems like a more effective defense than glowing in the dark.  I think that this may have had something to do with the fact that more of the Motyxia millipedes were attacked than the other millipedes.
