Cuttlefish tailor their defences to different predators

A couple of weeks ago, I wrote about a dolphin that has mastered the trick of killing cuttlefish and elaborately preparing them for a meal. It was a great story that highlighted just how intelligent and versatile dolphins can be, but it was a bit of a bittersweet report. The cuttlefish didn't exactly come out of it very well, which is a shame - they are intelligent creatures in their own right, every bit as fascinating as dolphins are. So it's with great glee that I report a new study that should help to restore the cuttlefish's credibility and cement its position as one of the cleverer denizens of the sea.
