Colour enhanced transmission electron micrograph of hemocyanin,a respiratory protein and pigment found in molluscs and arthropods. Like haemoglobin in mammals,hemocyanin is an oxygen carrying molecule. Each molecule is barrel-shaped appearing rounded end-on but oblong with transverse striations when seen from the side. Here,the hemocyanin molecules are from a marine whelk Burnupena cincta. They are a copper-containing protein (non-porphyrin) that occurs in solution in mollusc hemolymph blood .
