Oxygen consumption and its relationship to stepwise declining oxygen tension were examined in the common striped hermit crab, Clibanarius vittatus. 2. 2. Weight-specific oxygen consumption varied with body weight (W), according to the equation log V ̇o2 = 2.1639 + (-0.419 log W). 3. 3. Shell-less individuals of 1-2 g wet wt, where found to be oxygen conformers, since oxygen consumption ( V ̇o2) decreased with declining oxygen tensions. At ambient oxygen tensions below 35.4 mmHg, oxygen consumption remained constant, suggesting an increased ventilation. 4. 4. C. vittatus was found to survive in oxygen-free seawater for 5.5 hr, and no significant differences were found in oxygen consumption rates, for shelled and shell-less crabs, measured in water and air. 5. 5. The use of a K1 K2 index of oxygen independence, showed that larger animals were better able to maintain oxygen-independence during hypoxia than smaller individuals. 6. 6. C. vittatus displayed a pattern of no oxygen debt, once returned to normoxia. © 1983.749-753engArtigo10.1016/0300-9629(83)90579-0WOS:A1983QF09200044Acesso restrito2-s2.0-1842311148
