Abstract
Oxygen consumption and mean tolerance level at varying salinities were determined for four species of Brazilian crabs: Panopeus herbstii, Callinectes danae, Petrolisthes armatus and Pachygrapsus transversus. The oxygen consumption increased and tolerance levels decreased in dilute seawater in all species. The tolerance level of each crab reflects its lifestyle and habitat. P. armatus, found only in channels of free-moving salt water, had the lowest tolerance level to dilute seawater and P. transversus, a shore crab, had the highest level of all the species studied. C. danae showed the highest oxygen consumption rate at all salinities. This is presumed to be a result of its more active nature. P. transversus demonstrated the lowest rate of oxygen consumption in all salinities less than 60% seawater.
