I mentioned in my earlier post that cuttlefish not only use their camouflage to hide, but also to confuse their prey. I finally found a good video of a cuttlefish trying to do this. This is a great example of how quickly the skin of a cuttlefish can change colors too.
In this case its prey is actually a plastic toy put there by a scuba diver, so it's attempts to confuse it don't seem to get much of a response. The only one confused here is the cuttlefish. The next video shows a cuttlefish hunting real fish.
When the diver gets too close, the cuttlefish suddenly switches from hunting prey to camouflaging from what he sees as a predator.
