   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.

   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.

   Sep 4, 2024 · If you’ve ever seen a dolphin swim, you may have wondered why they undulate their bodies up and down, instead of side to side as fishes do. Though they have a fishlike body, cetaceans (a group comprised of whales, dolphins, and porpoises) are mammals that descended from land-dwelling ancestors – same as cats, dogs, mice, elephants, cows ...

   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?

   How do whales rotate?

   • In toothed whales this final angle is even wider, closer to 90 degrees. In baleen whales, a key rotation happens at the back of the skull, where it meets the spine. Rather than being perpendicular to the ground, as in the head of a dog, the back of the skull is tilted forward towards the snout.

   Where does a whale's skull fold?

   • In fin whales, the skull folded in a region in the back of the skull, near where the skull joins with the vertebral column. In the pantropical spotted dolphin, the folding is centered near the middle of the skull. The model Roston and Roth developed could inform how scientists view cetacean evolution.

   How does a dolphin's nasal passage shift during embryonic development?

   • New research is shedding light on how the nasal passage of dolphins and whales shifts during embryonic development from emerging at the tip of the snout to emerging at the top of the head as a blowhole. The findings are an integrative model for this developmental transition for cetaceans.

   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.
