I agree that they certainly do not change color in the manner/degree that cephalopods do, but there is evidence of limited color-matching to avoid predator detection (google "Predator-specific camouflage in chameleons"), you just might need scientific equipment to notice it.
It certainly is an interesting story to follow - the illegal exports happened in Nov. 2010, public outcry finally got bad enough that the government had to do something to appease the public in Aug. 2011, and now people are getting fired, with prosecution likely to follow. Are these guys really...

Hello, I haven't been very active on this forum, so I'll introduce myself. My name is Phil; I'm a graduate student working on the ecology and conservation of Tanzanian chameleons. I've got one paper out so far (http://herpconbio.org/Volume_6/Issue_3/Patrick_etal_2011.pdf) with some more in the...
I would largely agree with Seeco - the trade was very small in the 1970's, but grew as chameleons became more and more popular as a result of publicity. It's the same story for a thousand other reptile species. Somewhat unfortunately (for wild populations), chameleons remain fairly difficult...
I second Stevie - any way to read that article (Usambara Giant Three Horned Chameleons by Luis Wiedemann and Nicola Lutzmann) now that I've missed the actual printing?
