platygyra and goniastrea

[kawicivic]

can anyone tell me what the main difference between these two coral species are? what are the best ways to tell these corals apart?

Platygyra are GENERALLY more snious & labyrithine. Goniastrea are a bit more like a Favites & generally have deeper coralites. That being said, there are species that are very hard to distinguish.
