The erythrocytes of the cod, Gadus callarias have a flattened discoid shape; each contains a peripheral marginal band of approximately 10 microtubules and a centrally placed nucleus. The cytoplasmic and nuclear haemoglobins have a paracrystalline organization; individual filaments, presumably polymers of haemoglobin, are grouped into bundles which course in all directions through the cell. This organization shows a remarkable similarity to that of deoxygenated haemoglobin in sickled human red cells. However, paracrystalline haemoglobin in the cod is characteristic of the normal red cells and is not associated with a crenated shape.
