Blind Chameleon!

[Nelli]

A blind chameleon can still change its colour according to its environment. But how?

[Gef]

Surely anyone who knows that a blind chameleon can still change colour will know how it is done!

MMmmm... I think that's why I'm asking darling!

Okay I'll have ashot at this. I don't think that the ch. sees that its on a colour and decides to change to match it. I think that what happens is that sensors in the skin react to the reflection off whatever surface the ch. is on to trigger the change

Contrary to popular belief chameleons do not change colour to match their surroundings. Their colour change is affected by hormonal or mood changes and is a reflection of nervous activity. The colour change is a means of communication. Changes occur when they are frightened, sexually receptive, carrying eggs, courting etc. Their 'calm' colour pattern is usually the only one that is likely to be an effective camouflage colour. So, to answer your question, a blind chameleon can still change colour the same way as a blind human can still speak because this process is nothing to do with it's environment.
