It is homologous with the nostril of other mammals, and evolved via gradual movement of the nostrils to the top of the head. As whales reach the water surface to breathe, they forcefully expel air through the blowhole. Baleen whales have two blowholes positioned in a V-shape while toothed whales have only one blowhole.
Do dolphins have spouts?
Similar to whales, dolphins also have a blowhole that is located at the top of their heads, through which they expel CO2 and remaining air in their lungs. During the powerful exhale, dolphins will spray up water at the surface of the ocean, producing what is referred to as a dolphin “spout”.
What animals are included in cetaceans?

Where is the blowhole in a cetacean’s head?

What are blowholes and how do they affect the environment?
The blowholes are one of the primary attractions in Samoa. Other blowholes include the Kiama Blowholes in Australia and the blowholes of Wupatki National Monument, US. Continued action of blowholes eventually changes the topography around it. The holes cause erosion of the region around the crevices and lead to the enlarging of the sea caves.
