Today, thanks to Creature Cast, we learned about both multicellular organisms and squid iridescence. Although I think much of it was over P's head, he seemed to grasp some of it. We talked about it more, made reference to how the iridescence was similar to butterfly wings (like in the video), and then sought out videos to showcase it in "real life".
we looked at some of Loligo squid (the kind mentioned in the Creature Cast), including some neat light displays. At about that point, we watched the NOVA "About Cuttlefish" short, and had to learn more!
NOVA has a website on these "Kings of Camouflage", and we enjoyed learning more about the Anatomy of a Cuttlefish (including its weird W-shaped pupil, its 200 chromatophores or pigment cells per square millimeter, and its blue-green blood!) and watching videos of these Quick Change Artists.
Pretty awesome stuff.
