Description

Why is horseshoe crab blood blue?

The oxygen-carrying pigment in horseshoe brab blood is a protein called hemocyanin. It is very similar to the hemoglobinmolecule we have in our blood. Hemoglobin gets it's red color (which makes our blood red) from the iron molecule in the center of the protein. Hemocyanin contains a copper molecule which results in a blue color.
