1. In coral reefs, there will be many more creatures such as Tosanoides aphrodite, or whatever. Maybe, comouflaging fishes can be found too.
2. We may found creatures there, then how about new material? Animal poop, diamond, coal, fossils, whatever. Some extravagant scientist can make a robot that can change our life. Who knows?
3. Coral reef is already many creature's habitat. We, humans are destroying other same life with life. No more climate changes! Not only ichthyologists knows it, some of us know it too!
4. NOW DONE
