By Brooke A whale is a mammal. There are different kinds of whales. There are Baleen whales and Toothed whales. I learned that whales have flukes. Scientists take pictures of their flukes so if they see them again they will know which one they are by their special fluke markings.
Baleen whales have strainers in their mouthes to catch fish.
The fish get studk in the strainer. To catch fish they jump out of the water, suck up the water with the fish, and the fish get caught in the baleen. My favorite is the killer whale because you can train them easily. Killer whales love to have their tongues rubbed. Toothed whales use their teeth only to capture prey, not to chew it.
