User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-5043481-20120903174919

I have a theory as to how certain monsters (chameleos and Narga sub) turn invisible.

I think that the monster is covered in many very fine and short hairs that are different colours. To create camoflage the monster raises the colour hairs that are needed to create an image of the background. The flexing in chameles, travels in a wave from the horn tip, so when the horn is removed the hairs don't know what they are doing and he is visible.
