KINGS OF CAMOUFLAGE
Cuttlefish are some of the strangest animals on the planet. These shape-shifting creatures can hypnotize their prey, impersonate the opposite sex and even kill with lightning fast speed. More accomplished masters of disguise than any chameleon, they have a remarkable ability to change their skin color - even their shape - to blend into most any background. They have the largest brain-to-body ratio of all the invertebrates. But are they capable of learning and remembering complex tasks? With beautiful underwater footage and in-depth expert interviews, NOVA gets up close and personal with these bizarre and amazing animals.
