Do spiders have transparent blood? Spiders have blue blood. In human blood oxygen is bound to hemoglobin which contains iron, giving it the blood a red color. In spiders, as well as other Arthropods and Molluscâ¦s, oxygen is bound to hemocyanin which contains copper, giving its blood a blue color. The same interaction that causes oxygenated blood to color, also causes iron rust to appear reddish and the oxidized copper to appear green.
Human blood is red, ranging from bright red when oxygenated to dark red when not. It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in color between deoxyhemoglobin and oxyhemoglobin. There exists a popular misconception that deoxygenated blood is blue and that blood only becomes red when it comes into contact with oxygen. Blood is never blue, but veins appear blue because light is diffused by skin.
