Martin Moynihan and A. Rodaniche believed that Sepioteuthis sepioidea had a complex visual signaling system on the magnitude of language. Since then, most researchers have dismissed this belief saying that a cephalopod with 10-40 body patterns does not equal the "infinite" signals exhibited by a language. Does every language need to be in the confines of human language (i.e. grammar)? What about the Bees waggle dance? With new information on polarized light signaling and chemical communication, do you think multimodal signaling is present in some cephalopods? I just wrote my thesis on this topic , so I'm very interested to hear what other cephalopod researchers/keepers/fans think. I have lots of resources on the topic if anyone wants to read up (if anyone else is as geeky as I)! Cheers.
