Cuttlefish (Sepiida) There's nothing to see here. Nope. In reality, the yellow thing in the photo above is a cuttlefish doing its best to impersonate an aquarium plant. Shapeshifting masters of camouflage, cuttlefish can rapidly blend in with the scenery to avoid predators. They can disguise themselves to look like just about anything aquatic, assuming a vast array of postures and colors -- the latter being the result of pigment-containing sacs in their skin. A cuttlefish can control the size of the sac, called a chromatophore, and change color accordingly. The end result is a spooky feat of invisibility that's much more successful than James Bond's car.
