Hi, all! I was wondering if there is anyone out there who can give me some technical info regarding the ferret visual system. I'm taking a graduate seminar in perceptual systems right now and would like to know just for my own edification -- thought it would give me a better idea of just what they see and how well. Particularly, do they have rod-only vision? Do they have a fovea? etc. etc. I would greatly appreciate it if anyone can give me an answer. Thanks! -Tasha "It has been said that man is a rational animal. All my life I have been searching for evidence which could support this." -- Bertrand Russell [Posted in FML issue 2069]
