26 Respiratory characteristics of the hemoglobin-free fish Chaenocephalus aceratus Edvard A Hemmingsen a, b and Everett L Douglas a, ba Physiological Research Laboratory, University of California, San Diego, USA b Department o of Zoology, University of Missouri, Columbia, USA Received 25 August 1969. Available online 21 March 2003. 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.
