用英文答

Have you ever wondered what the difference is between a mammal and a reptile? There is a big difference between them. Reptiles are cold-blooded animals. Their bodies are the temperature of the air around them. Snakes and lizards are types of reptiles. Reptiles lay eggs. They live in a lot of different habitats.

Mammals are different. Mammals are warm-blooded. They do not lay eggs. They give birth to live young. The mother feeds her young with her own milk. Mammals, like the whale, date back to prehistoric time. Mammals evolved from living in the water to living on land.

Both reptiles and mammals are fascinating and have a lot of special traits.
