The blue whale needs vast quantities of food and oxygen due to its large size to sustain a healthy life. To acquire sufficient energy, the blue whale can eat as many as 40 million krill each day, which offers enough nutrition for their large bodies to grow and thrive in the ocean.
Whereas a person can consume about 15 percent of the oxygen they inhale, it is estimated that the blue whale is capable of consuming as much as 90 percent of the oxygen it breathes, making their deep breaths much more effective and adaptable to marine life than those of a human animal and most other land animals.
The difference about how the blue whale gets molecules from food and air
is that they are able to separate the passage of the esophagus and lung.
Whales are large mammals which are found in large water bodies. They
feed on smaller animals and they do so by eating their prey whole. The
separation of the esophagus and lung helps to prevent water inhalation
during eating.
The whale has a structure on the head known as blowhole which also
helps it to inhale air(oxygen) when at the surface of water.
