     • Blowhole: Nasal drift during evolution has resulted in dolphins’ nasal opening being located on top of their heads which allows them to breathe while swimming or resting underwater with their blowhole above the surface.

   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.

   Do Dolphins breathe through their mouths?

   • Dolphins do not breathe through their mouths in the same way as people can, they only breathe through their blowholes. In this way, breathing and eating are kept entirely separate in dolphins so that they can capture prey in their mouths and swallow it without the risk water getting into their lungs.

   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.

   Can a whale breathe through its mouth?

   • 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. Just like if you were to hold your breath for a really long time you let out a huge breath of air and then you try taking in a big gulp of air, a whale essentially does the same thing.

   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.

   Aug 26, 2021 · 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? Two scientists from the University of Washington and Duke University also thought about this question.

   Nov 8, 2016 · Whales do not have vocal cords like we do, but the way they make sound is similar. 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.

   During evolution, blowholes migrated to the top of the head, which facilitates breathing at the water surface. Whales cannot breathe through their mouth because, unlike terrestrial mammals, their digestive system and respiratory system are not connected.

   Whales and dolphins breathe through a blowhole located on top of their heads. This is a significant adaptation that allows them to breathe while swimming or resting at the surface. The blowhole is not just a simple hole.
