Abstract: The maximum activities of octopine dehydrogenase, lactate dehydrogenase,
alanopine dehydrogenase, citrate synthetase, a-glycerophosphate
dehydrogenase, malate dehydrogenase, and glutamate oxaloacetate transaminase
were measured in a range of muscles used in swimming by octopods,
squids, cuttlefishes, and a nautiloid. The high activities of octopine dehydrogenase
and the positive correlation between the activities of Krebs cycle enzymes
and enzymes used in the cytoplasmic reoxidation of NADH during aerobic
glycolysis indicate the importance of carbohydrates as a major fuel during both
anaerobic and aerobic muscle work. The maximum activities of enzymes associated
with anaerobic and aerobic carbohydrate catabolism correlate well with
the ways in which cephalopod muscles are used in providing propulsion during
