Some free-ranging birds and mammals dive for periods that substantially exceed those for which their usable O(2) stores are estimated to last. The mechanisms that extend the duration of aerobic diving include marked reductions in blood flow (and hence O(2) delivery) to certain organs and tissues, passive gliding and, most probably, regional hypothermia.
