Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen..reference wikipedia

Hemocyanin And Hemocytes
Some animals (like horseshoe crabs) have blue blood because they use hemocyanin carry oxygen to their tissues instead hemoglobin like we do. The copper in the hemocyanin makes their blood appear blue.
It is copper containing blue color protein that is a respiratory pigment in some animals .
In some species copper in the form of hemocyanin is used to transport oxygen.
The two molecules transport oxygen in cells, hemoglobin being the iron-based protein found in the blood of mammals, while hemocyanin is a copper-based compound found in some invertebrates, including mollusks and some crustaceans.
They actually have an open circulatory system, because their bodies do no contain blood vessels and their blood contains hemocyanin, rather than hemoglobin.
Iron if it's a hemoglobin based blood cell (then the blood is red). If it's hemocyanin then it's copper and the blood will be blue. Like the people of Pandora.
blue!!
it is so important and i love it so much :)
salat is important so yeah...
