Whales are fat because they aren't really fat! They look really fat because they are covered in a big, thick layer of blubber. That blubber is insulating, which means it helps to keeps them warm in cold, arctic oceans. If they are swimming in a part of the sea where food supplies are short, they can use the extra calories in their blubber to keep them going.
Have you ever wondered ?
If swimming is a good exercise to stay fit, why are whales fat ?
Has the steemit whales been too long chilling in the beach and became fat ?
