Wow! You guys are amazing

. I did a search for Leptastrea sp., then did a search for Heterocyathus aequicostatus. I found the Heterocyathus aequicostatus at a website, but while scrolling through the other photos, I found a pic of a specimen that looks very much like mine, but bigger. It's labeled as Pseudosiderastrea tayami of the Siderastreidae family. Of course, being a newbie, it's all Latin to me. What is it? What would be a good reference for a newbie to get a handle on the classification, morphology, etc. of corals?
