Summary The haematological parameters (haematocrit, erythrocyte number, haemoglobin concentration, MCHC, MCH, oxygen-carrying capacity, pH, p1/2, Φ, pCO2, pO2) of the Antarctic fish Aethotaxis mitopteryx DeWitt are reported. The erythrocyte number (0.39 × 1012/1) and the haemoglobin concentration (27.8 g/l) were found to be among the lowest values known for red-blooded Antarctic fishes. Among the species of the family Nototheniidae, this is the only one found so far to have a single haemoglobin in its blood. The results have been analysed in comparison with those of other Antarctic species, in an effort to establish correlations between the physiology of this pelagic-benthopelagic fish and its ecology. From the haematological parameters in this study and the functional properties of haemoglobin outlined in the following paper, it is suggested that A. mitopteryx has an extremely sluggish mode of life.
