2 thoughts on “2. Fishes have gills to breathe in water. How do whales breathe?”
Explanation:
Whales and dolphins are mammals and breathe air into their lungs, just like we do. … They breathe through nostrils, called a blowhole, located right on top of their heads. This allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water.
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. … 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.
