In marine mammals, similar disorders may be directly related to anthropogenic threats or sickness and blood PMP levels may be affected. We propose that detecting platelet phosphatidylserine (PS) exposure and PMP formation can serve as a valuable diagnostic and monitoring tool for these pathologies in marine mammals. Our group has adapted a methodology for evaluating real time PS exposure and PMP formation in this taxonomic group. This method employed for the first time in species like bottlenose dolphins, beluga whales, walruses and California sea lions, represents a novel and valuable tool to both clinical assessment and further research on platelet function.
