I am trying to identify this fairly common species from Cancun/Cozumel. Thanks for any help.

It is either Montastrea annularis or Montastrea cavernosa.

The polyps look more like M. cavernosa but it is hard to distinguish the two based on a close up of the polyps with no scale. Do you have a picture of the entire colony or something in the picture to show the size of the polyps? M. cavernosa has larger polyps and froms a smooth bolder like colony. M. annularis has smaller polyps and froms a bumpy colony bolder or plates.

Here are some pictures of mine that show the colony shape of the two species.

I think the Montastrea annularis is the correct answer. My memory gets worse daily but that seems to be what I remember, the pictures helped. I kept trying to convince myself that the scale of the polyps were larger.

Thanks.

I believe it's M. cavernosa based on the height and size of the polyps. The M. annularis tend to look conjoined (I don't know if they are though).
