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.
The venous blood is never blue, it is a darker color of red than arterial blood, not blue. The color is a burgundy red or maroon color. Blood is bright red in the arteries and dark red in the veins.The reason venous blood is a darker red can be partially attributed to the slightly less oxygen in the blood in the veins.ed blood cells are red because the iron in the heme group of the four hemoglobin proteins react with oxygen (think what color rust is) to produce a red color.
