Question

How do whales stay active for so ling on only one breath?

Answer 1

their heart only beats around 8-20 beats per minute

Answer 2

A whale's lungs work like ours do, but they make the most of each breath. In one breath, a humans body can absorb about 15 percent of the oxygen inhaled. The whale, on the other hand, absorbs as much as 90 percent of the oxygen it breathes in

Answer 3

Whales have greater amounts of myoglobin than other animals, allowing them to store larger amounts of oxygen at a time. Whales also make more efficient use of this oxygen. When they dive, their heart beats more slowly and select arteries are constricted.

Answer 4

As we know whales can't breath underwater but doing the above methods can hold their breath from 40-90 min
