Abstract
Studies on the Antarctic hemoglobin-free fish Chaenocephalus
aceratus showed that the oxygen consumption was unusually
low; Low blood lactic acid levels at rest and after anoxic stress
indicate no unusually high anaerobic metabolism. The main
respiratory compensation to the absence of hemoglobin
appearsto be an increase of blood volume and a high
cutaneous respiration.
