Whales & Dolphins Are Mammals
Know that whales and dolphins are mammals, not fish — they breathe air, are warm-blooded, and feed their babies milk — even though they live in the ocean
What a learner can do afterwards
- State that whales and dolphins are mammals, not fish
- Give at least two reasons why: they breathe air and feed babies milk
- Explain that living in water does not make an animal a fish
The lesson
Whales and dolphins live in the ocean. But they are not fish. They are mammals, just like you and me.
Mammals breathe air, just like you do. Whales and dolphins come up to breathe. Mammal babies drink milk from their mothers. Whale and dolphin babies do this too.
A baby dolphin swims next to its mom. It drinks her milk to grow big and strong. Every few minutes, it swims up for air.
Living in water does not make an animal a fish. Ask if it breathes air and drinks milk. That tells you it is a mammal.
Whales and dolphins breathe air and feed their babies milk. That makes them mammals, not fish.
