blindfold squid & other fascinating things

You might know that squid can change the colour patterns on their skin. But how does this happen? & if the changes are in relation to a changing colour in the environment, how do squid know about this - do they see the change, or sense it in their skin? (Hence the 'blindfold squid' of my title.)

Well, over on PZ's there's a lovely podcast which I enjoyed so much that I've embedded it here as well. Enjoy! (NB for teachers - 'Creature Cast' seems an excellent classroom resource.)
