A respiratory pigment is a metalloprotein that serves a variety of important functions, its main being O2 transport.[1] Other functions performed include O2 storage, CO2 transport, and transportation of substances other than respiratory gases. There are four major classifications of respiratory pigment: hemoglobin, hemocyanin, erythrocruorin–chlorocruorin, and hemerythrin. The heme-containing globin[lower-alpha 1] is the most commonly-occurring respiratory pigment, occurring in at least 9 different phyla of animals.[2]
