摘要：

1. At 35-degrees-C a maximal VO2 value of 110 ml O2/kg/hr was obtained with a significant decrease in the value at 40-degrees-C. 2. The Bohr-effect for P. warreni is -0.28 and does not change significantly at 15, 25 and 35-degrees-C. 3. The ability of the crab to extract oxygen from the water medium during a single exhalation is on average 41.2% whilst the limitation diffusion (L. diff, Piiper, [1982], A Companion to Animal Physiology, pp. 49-64. Cambridge University Press.) is 0.84. 4. Compared to land and marine crabs, in P. warreni, the PaO2 (29.5 mm Hg) and the PvO2 (15.3 mm Hg) is low.
