Well I didn't really research it, I typed it in google and I recognized the pictures that came up and I told you I recognized it. If you would like to know where I do my research I mainly go to yard sales and used book stores for books on Oceanography and the hobby. If I don't have a book on something I use the Internet. I use a variety of sites even if their just for quick info and not research such as Live Aquaria, Saltwater Smarts, Reef Builders, Aquanerd , and Fish Channel, but those are just the ones I use often. Even if some of the websites are "quick info" sites, they still can teach you something new and give you a little more knowledge on the subject.
