📖 Read the story
Seals are amazing animals that live on land and in the ocean. They have a special superpower. They can hear very well in both places! Most animals can only hear well in the air. Scientists wanted to know why. They used X-rays to look inside a seal’s ear. They found something very cool. When a seal goes underwater, parts of its ears fill with blood. This blood helps the seal hear sounds in the water. Seals use their ears to find food and talk to their friends. They also use them to stay safe. This skill began many millions of years ago. Humans cannot hear well underwater because water is very heavy and thick. But seals are different. They are the only mammals that can hear perfectly in two worlds. This helps them live a happy life in the sea and on the beach.
