How do whales breath?
Humpback whales are voluntary breathers meaning they have to consciously breath in and out (it’s not an involuntary reaction like we have). They swim to the surface to draw in air through their blowholes. Whales have limited breathing functions through their mouths. When a whale inhales, it fills up its lungs to capacity each tie and then exhales 90% of its air supply with each breath. Humans exhale only 25% of their lung capacity. The whales exhale through the blowholes, a whole exhale in less than half a second and sometimes at over 300 mp, while inhaling takes place in a leisurely second. What adaptations have whales made for voluntary breathing? Voluntary breathing is an important adaptation for whales. They must constantly be aware of their location in the water. Since they are mammals and can drown if they flood their lungs with seawater, they must know when it’s safe to take a breath. It is believed that the area around their blowholes is very sensitive and allows them to know w
