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.
