Whales have minute eyes: those of a blue whale's are no larger than a small plate. 4.The whales' lungs can store at each inspiration 5,000 liters of air. They usually breathe at every 15 minutes but they can hold their breath up to over an hour in the case of the sperm whale. The humpback whale can dive to 250 m (833 ft) for 20 minutes. The blue whale's exhaling blow can be 12 m (36 ft) tall!

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.
