Blue Whales are mammals. They need to breathe under water just the way all other of its family members need to. Blowholes are its Nostrils that are located on the top of whale's head.Blowholes are covered by muscular flaps that keep water from entering them when the whale is under water. Blowholes keep them stay underwater for long time as they cannot breathe with their mouth..
