Answer:

1.Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. ... Whales even give birth to live baby whales that will get milk from their mom for food. Fish lay eggs, which must still grow into a baby fish. So whales are indeed mammals and not fish!

2.Fish have gills that extract oxygen from the water and allow it to live underwater their entire lives. On the other hand, whales do not have gills but instead have one or two blowholes that connect to their lungs, which allow the whale to breathe in air.

3.Though whales are mammals and fish are not, they are similar in some ways. Both have fins and a tail, which helps them swim and stay upright in the water. But these similarities are in appearance only. ... Fish, on the other hand, have vertical tails, which move from side to side.
