Ocean Animals
> Do you like sharks? Sharks, like many other animals, live in the ocean. Whales and dolphins live in the ocean, too. If you go to the ocean, you may also see crabs, eels, and many kinds of fish. You may even see an octopus! *Many animals live in the ocean!* Would you like to take a trip to the ocean?

main idea — it's the overall message of the story.

✔ Main Idea: *Many animals live in the ocean.*
