When I was a grad student, a group of faculty and grads talked about doing an animal communication class. Despite none of us knowing anything about the subjects, we figured we would each take a week and present some of the research and ideas relating to communication within the species. There were some obvious choices: bird calls, orangutans, dolphins. My choice was the cuttlefish. It amazes me that more people are not as fascinated by cuttlefish as I am: not as lunch or as a beak sharpening implement, but as a highly communicative and equally unusual creature. So, I was pleased to see that Google Video has this Nova special on cuttlefish available on the web.
