In fact whales are able to take in much more usable oxygen than land animals and humans. One estimate states that a whale may be able to store and use up to 90% of the oxygen they inhale. Whales are also able to shut down non essential functions in order to maximize the efficiency of their oxygen usage. Depending on the whales species whales have been known to hold their breath anywhere from 5 minutes up all the way up to 90 minutes during deep dives. Due to their consistent conscious effort to control their breathing whales are referred to as conscious breathers.
Diving mammals will slow their heart rate, stop their breathing, and shunt blood flow from their extremities to the brain, heart, and muscles when starting a dive. But champion divers, such as elephant seals, can hold their breath for about two hours. It was known that they rely on internal oxygen stores when they're down there, said Michael Berenbrink, a zoologist at the University of Liverpool, England, who specializes in how animals function.
