Well it is definitely Not :Oreaster reticulatus

By the way O. reticulatus (<50cm)is also a Caribean species, although the similiar Oreaster occidentalis renamed Pentaceraster cf. cumingi(<20cm) is an Hawaii to Eastern Pacific species. Neither resemble Emily's star. Both are fairly large when compared to Emily's.
I am curious EmilyB and Delphinus, What about this star do you feel is different? Delphinus you mentioned "subtle enough differences", what are they? I'm not trying to be argumentative, I view this as a debate.
As to the store owner saying he thinks it is Indo....I think that was just a standard reply. A majority of store owners/employees are anything but knowledgable, and before every store owner posts a reply to that....notice I said a "majority" not ALL. Anyways It may have come through an LA shipment from QM or a similiar supplier that consolidate shipments from around the world for their availability list.
Even though Emily is probably tired of this debate by now, I too would like to see a closer picture too.
I couldn't get the link to work sorry.
This is what I believe you have:
