Hi WM!
I saw this post come up a few days ago and I'll admit that I don't know much about them. Since then I've dug out my Necas book on chameleons (my cham bible) and read the AdCham taxonomy sheet on these guys just to refresh my memory.
They are strange little guys and as you say defy all regular chameleon behaviours. They are fast! My regular chams here can move pretty quickly if they want to, but these Namaqua chams can RUN! 5km/h, that's just crazy for a chameleon. I particularly like the way they are able to capture and eat venomous prey as well. Considering the harsh living conditions in the wild, they have to make due with what's around.
Interesting animals that's for sure, and would be neat to work with them, but I don't think I've got the space and knowledge to keep them properly. Some day maybe...
Thanks for this thread, you made me do some reading and learning new things is always good.
