Some clever people have gotten themselves a grant from the National Science foundation to make awesome hand-drawn cartoons of animals to pair with conversational interviews with scientists explaining their research. It’s kind of like if This American Life was a charmingly low budget biology vlog. It’s called Creature Cast, it’s creative commons attribution-noncommercial-share alike, and you can follow along with the episodes and related postings on the Creature Cast blog. The first episode is about the colors of the squid loligo opalescens, which you’ve probably eaten if you’ve ever had restaurant calamari. The concepts are communicated clearly and the drawings are delightful.
And here is the best video I was able to find of some of the actual behavior discussed by the interviewed scientist. It is a different species of squid, but I think the same principles are in evidence.
