Whales are mammals who breathe air into their lungs. Blowholes are a whale's nostrils and are located on the top or back of the whale's head. Blowholes are covered by muscular flaps that keep water from entering them when the whale is under water. In the relaxed state, the flap covers the blowhole. A blowhole leads to the whale's trachea and then to its lungs. Unlike us, whales cannot breathe through their mouth; they only breathe through their blowholes.
The descriptive features of the humpback whale include two blowholes and notched flukes (tail). The pectoral fins are 1/3 the length of the animal and are the largest flippers of any whale.
A gray whale's respiratory system consists of blowholes located on the top of its head, which it uses to breathe air at the water's surface. The blowholes connect to the lungs, allowing the whale to exchange gases necessary for respiration. Gray whales are mammals and require oxygen from the air to survive.
