Children of Ruin, by Adrian Tchaikovsky, explores the concept of squid communication. I'm about half way through, and enjoying it!

I'm reading Children of Ruin right now and it's quite funny finding this article here right now. :)

>> 'Arthur C. Clarke used giant squid in many of his works. In The Deep Range, a squid of exaggerated size is captured and exhibited. In the short story "Big Game Hunt", a device capable of controlling the behavior of invertebrates is used in an attempt to capture and film a giant squid. In Childhood's End, one of the characters stows away on an alien spacecraft by hiding inside a model of a giant squid battling a whale.'
