tx51210 0 Posted June 21, 2007 I am trying to identify this fairly common species from Cancun/Cozumel. Thanks for any help. Share this post Link to post Share on other sites
acroporas 0 Posted June 21, 2007 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.

tx51210 0 Posted June 21, 2007 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. It is either Montastrea annularis or Montastrea cavernosa.

james 0 Posted June 21, 2007 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). Cheers James Share this post Link to post Share on other sites
