DAVID: Now, now, I'm sure that cuttlefish have a means of communication. They do become mammas and poppas. Canoodling requires communication, but I don't think they talk about shark avoidance in any meaningful way.-> dhw: I reckon my Kevin and Kitty might even recognize threats to their survival, such as that dirty great shark coming to swallow them up. And I reckon they might not only try to find ways not to get swallowed up, but if they found a way, they might even tell their fellow cuttlefish. After all, if animals, birds, insects, and even little bacteria can do it, I reckon Kevin and Kitty can too. Don't you?-I doubt it. Bacteria have quorum sensing and horizontal gene transfer, run automatically. I doubt if 'cuttlespeak' exists, so they have to show the method as a shark approaches. The uninitiated will get eaten before the method is acted out.
