Hemocyanin is an oxygen-transport protein found in many invertebrates. It is a metalloprotein that contains copper atoms.

Hemocyanin utilizes copper atoms to bind and transport oxygen. Each oxygen binding site in hemocyanin contains two copper atoms.

In contrast, hemoglobin, the oxygen-transport protein in vertebrates, uses iron atoms (specifically, heme groups containing iron) for oxygen binding. Hemocyanin is responsible for the blue colour of the blood (hemolymph) in organisms like mollusks (e.g., snails, squids) and some arthropods (e.g., spiders, crustaceans) when oxygenated.
