Cuttlefish are amazing animals! They can change their color faster than a chameleon because they have chromatophores which are special cells. They can change their pigment to complicated shapes to fit their background, and amazingly enough most cuttlefish are color blind!
Cuttlefish are color blind and yet they are masters of camouflage. Scientists don't know how they read colors, which they can do in the dark, perhaps something about their skin.
A strange fact about the cuttlefish is that it can adopt the female coloration along one side of the body as well as retain the male coloration on the other side. Male cuttlefish are extremely alert when it comes to the females, especially if she is laying the eggs. The male will guard aggressively over the female and this is when another approaching male will use his ability to have a dual look to access the female and trick the male.
