Abstract
1. The blood of the conch Busycon canaliculatum is highly oxygenated at the two sites of gas exchange with the ambient medium, the gill and the mantle. An exceptionally small venous reserve is maintained in prebranchial blood, suggesting an important respiratory role of the oxygen transport system. 2. In normoxic water the physiological pH range is 7.85 to 8.04, where the reverse Bohr shift of Busycon hemocyanin is essentially absent. During non-lethal exposure to hypoxia, blood pH does not decrease substantially and thus the reverse Bohr shift cannot be interpreted as an adaptation to low oxygen conditions.This publication has 5 references indexed in Scilit:
