Cuttlefish are less well known than other cephalopods, but just as interesting:
- Their blood is greenish-blue because it uses a copper-containing protein, hemocyanin, to carry oxygen instead of the red iron-containing protein hemoglobin we're familiar with.
- They are masters of disguise because they can rapidly change skin colors to camouflage themselves.
