HABITAT Okay, I mentioned the sea earlier. Thats where starfish live!! They live in all the worlds oceans, even the arctic! Can you guess where starfish live in the ocean? If you don't want to will you do it for ice cream? Ok! Guess away! Yes they live in shallow water! Yeah, they live in deep water, too!! I know I'm confusing you, but they live in shallow and deep water!! So you can have ice cream. IF!!! You can tell me the answer to this question... do they live in fresh water? No they do not live in fresh water! Now nobody gets ice cream! HA!
