| Some whales have teeth. Some don't. Whales that have teeth eat fish and small ocean animals. Whales that don't have teeth eat very very small animals called krill or plankton. | |

|
Some whales weigh up to 200 tons! That is more that 200 large cows. |
| Whales are not fish. Whales have live babies. They also breathe air. We call whales mammals. |
