タマゴは丸くない？上下がある理由
Eggs look round at first, but they actually have a pointy end and a round end. This special shape has a purpose. The pointy end helps keep the egg from rolling away in the nest. The round end gives more room for the chick to grow inside. Also, this shape helps the egg move smoothly inside the bird's body. It’s a great example of how nature designs things in a smart way!
