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 because it contains a large number of red blood cells, which contain hemoglobin. Hemoglobin is a red-colored, iron-containing protein that functions in oxygen transport by reversibly binding to oxygen. Oxygenated hemoglobin and blood are bright red; deoxygenated hemoglobin and blood are dark red. Human blood does not appear blue under any circumstances. In fact, vertebrate blood in general is red. An exception is skink blood, which appears green because it contains a large amount of the protein biliverdin.
