   How do whales & dolphins get on top of their head?

   • Dolphins and whales spend their entire lives in the ocean and must come to the surface for each breath. The location of their “nose”, the blowhole, on the top of their head allows them to exchange breathing air efficiently during the sometimes brief surfacing. But how does the blowhole of whales and dolphins actually get on top of the head?

   Why do whales have a blowhole on top of their head?

   • The purpose of having their blowhole on top of their head is for the convenience of not having to lift their entire head out of the water to get a breath. In fact a whale can’t even breathe through its mouth it can only breathe through its blowhole. Its mouth is just used for eating, nom nom nom.

   How do whales move air?

   • In humans, air moves over our vocal cords, which vibrate and make different sounds based on the tension and shape that they're in. Toothed whales also move air, but not over vocal cords. They move the air through their blowholes. They have phonic lips inside the blowhole that vibrate when air passes over them.

   Where does a whale's nasal passage start and end?

   • It rises at an angle to the roof of the mouth and ends at the top of the head as a blowhole. During the embryonic development of whales and dolphins, the nasal passage initially lies parallel to the palate and opens at the tip of the snout, similar to other mammals.

   How does a dolphin breathe in a blowhole?

   • After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin’s lungs. When a dolphin surfaces for air, he breathes out (exhales) first and then breathes in (inhales) fresh air; it only takes a fraction of a second for the dolphin to do this.

   The V-shaped double blowhole of a gray whale. In cetology, the study of whales and other cetaceans, a blowhole is the hole (or spiracle) at the top of the head through which the animal breathes air. In baleen whales, these are in pairs.

    Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
