Cockroach have white blood because it lacks hemoglobin in its cells. Grasshopper's blood is green in colour because of the presence of chlorocruorin in the blood for transporting oxygen. Octopus blood is blue in colour because its blood contains the copper-rich protein hemocyanin for transporting oxygen.
