# The Whale Who Used to Walk Canonical: https://littlestorybook.ai/learn/en/the-whale-who-used-to-walk Language: en · Ages: 4-5 · Illustrated story lesson (interactive), free Reviewed for child-safety · gentle by design. ## Quick answer Whales evolved slowly from land animals and still come up to breathe air. ## Key takeaways - Whales were once related to animals that walked on land. - Whales changed very slowly over a very long time. - A whale’s front legs became flippers for swimming. - Whales cannot breathe underwater like fish; they come up for air. ## The lesson text Look at the big blue whale, splashing in the deep, deep sea! It is bigger than your house, bigger than a school bus. But here is a funny secret: a long, long time ago, whales had little legs and walked on the land, just like a puppy! Can you picture it? A small furry animal, about as big as a dog, walking by the water on four little legs. It loved the water. It liked to wade in the shallow part, the way you splash your feet at the edge of the bath. Because the water had lots of fish to eat, the animal stayed near the water more and more. What do you think happened to its legs after a long, long time? Let's see! Because it swam so much, the babies that were best at swimming grew up and had more babies. Slowly, slowly, over more years than you can count, the back legs grew tiny and disappeared, and the front legs turned into flippers, like wide soft paddles. So a walking animal became a swimming animal! That slow change is called evolving. Here is the wow part that grown-ups love: a whale still cannot breathe underwater like a fish! It has to come up to the top and take a big breath of air through a hole on top of its head, just like you come up for air in the bath. Try it right now: take one big breath in, hold it, then let it out with a "pwoooosh!" That puff is just like a whale's spout! So remember, little one: the whale did not change in one day, like magic. It changed slow, slow, slow, over a very long time, because it loved the water and the water gave it food. Next time you splash in the tub and come up to breathe, you can say, "I breathe like a whale!" The giant of the sea once had little legs, and that is one of the most amazing true stories in the whole wide world. ## Lesson scenes ### 1.
