Answer 2

Hey dear ur answer is here....

Octopus

Society elites aren't the only blue bloods. Several species of octopus have blue, rather than red, fluid running through their veins. The blue comes from a copper-rich protein called hemocyanin, which carries oxygen from the lungs to the bloodstream and then to the cells of the octopus's body.
