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.
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.
Aug 12, 2021 · Most of them keep their noses and their mouths in front of their face, but dolphins and whales transform their whole heads to change the direction of their nasal passage while keeping the snout facing forward.
How does echolocation work in whales and dolphins? Echolocation relies on sending and receiving sounds. Toothed whales create noises by blowing air through what is known as their “phonic lips,” a vibrating tissue located along their nasal passage, beneath the blowhole on the top of their head.
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.
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.

Aug 5, 2021 · Today’s cetaceans also sport a unique type of nasal passage: It rises at an angle relative to the roof of the mouth — or palate — and exits at the top of the head as a blowhole. This is an apt adaptation for an air-breathing animal at home in the water.
