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?
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.
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.
Aug 16, 2021 · 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...
Aug 5, 2021 · 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.
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.
