Question

imagine that you are swimming next to the largest animal ever to have existed. it’s as long as three school buses, weighs between 200,000 and 300,000 pounds, breathes air, and lives in the ocean. this animal is a blue whale, and its enormous size means that it needs to eat a lot of food and take in a lot of oxygen. blue whales must dive deep underwater to feed, which means that they spend a lot of time holding their breath. how can a blue whale survive 20 minutes without taking a breath?

Explanation:

The problem is about the biological adaptations of blue whales that allow them to hold their breath for 20 minutes. This falls under the subfield of Biology (Natural Science) as it deals with the physiological and anatomical features of an animal.
