Answer:

Whales and dolphins use their lungs to breathe air also. That's one reasons why they come to the surface of the ocean. Sometimes they lie right at the surface of the water, with just a part of their back sticking out.

in fact whale is a mammal and humans are also mammals...

so both of us were having the same respiratory system . hence, comparing the berating rate of fishes with humans...

breathing rate in fish is higher than humans because its body is used to breathing through gills.Air has around twenty times more oxygen than water does, and water is also heavier than air, so it's harder to move into the fish's gills. Since there's less oxygen in the water and the water is harder to move around, fish need to breathe more quickly.
