A science book gives facts. Some science books tell us about animals. Some tell us about plants. Some tell us about outer space. This page tells us about animals.
Do you know that not only the fish but also some animals live in the sea? For example, the whale is not a fish. It can’t breathe in the water. It swims in the water. But it comes up for air.
The blue whale is the world’s biggest animal. There are other sea animals, too. One is called the dolphin. Dolphins need air to live. They breathe air, as whales do. Dolphins are very clever. They sometimes seem to speak to each other.
Many other animals live near the sea. Seals（海豹）and otters（水獭）love the sea. They swim and play there. They eat fish and sea plants. Seals and otters have thick fur. The fur keeps them warm.
