Coral reefs are considered to be “houses” for many life forms. You would see sponges, corals and anemones, sea worms, echinoderms, crustaceans, mollusks, coral reef fish, unusual reef fish, sharks and rays, marine reptiles, and marine mammals. If you were to walk through a coral reef, you would see all these things around you. You may also find a whole new species of fish. Divers have spent more money to explore coral reefs than to explore the moon. This is because, there are so many new species that we find, and will find in the future. Walking through a reef, can show you so many things. It can show you fish you have never seen before. Or underwater plants you have never seen before.-->Do you think that humans can possibly live near coral reefs someday?
