CC   -!- FUNCTION: Involved in oxygen transport from gills to the various
CC       peripheral tissues.
CC   -!- SUBUNIT: Heterotetramer of two alpha chains and two beta chains.
CC   -!- TISSUE SPECIFICITY: Red blood cells.
CC   -!- MISCELLANEOUS: This fish has two hemoglobins: cathodic and anodic. The
CC       cathodic Hb and anodic Hb display small and large Bohr effects
CC       respectively. In addition, the cathodic Hb displays a reverse Bohr
CC       effect and appreciable phosphate effects.
CC   -!- SIMILARITY: Belongs to the globin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00238}.
