What do whales breathe Breathing plays a very important role in the life activities of animals, and different animals have different ways of breathing. To understand the way whales breathe, we should first understand that they are mammals. Living in water, they are an aquatic mammal. Although they differ from terrestrial mammals in some characteristics, they are similar in their breathing patterns. Whales use their lungs to breathe. Unlike the way fish use gills to breathe. In addition to the lungs, the nostrils also play an important role in their breathing.
When taking a specific breath, the whales will choose a suitable time to breathe, and then stick their heads out of the water, they will expel the air from their lungs, which will be ejected from the nostrils together with the surrounding sea water. Then the whales take a lot of air into their lungs, which allows them to dive for a long time.
The organs and methods used by whales to breathe have been mentioned above. It can be seen that whales must be out of the water when they breathe, and they can't breathe at the bottom of the sea. Therefore, this feature makes whales can not always be hidden in the sea bottom, but need to come out of the water to breathe every other time, and it is not possible to stay on the sea bottom for a long time. However, unlike human and other animal breathing, whales can choose their own specific time of breathing, while humans and most other animals are basically passive, must constantly breathe. After a breath, the specific time that different whales can last is different, and some whales can last for several hours.
