Do octopuses swim or walk?

Why does an octopus have blue blood?
Well, the blue blood is because the protein, haemocyanin, which carries oxygen around the octopus’s body, contains copper rather than iron like we have in our own haemoglobin. One heart circulates blood around the body, while the other two pump it past the gills, to pick up oxygen.
