In Jamaica, they exist on sandy channels between reefs and on muddy slopes close to river mouths.
[4] They have non-aggressive polyps which makes them vulnerable to aggressive species of coral[5] and have been seen to grow more horizontally than vertically.
After fertilization, the new larva floats in open water and eventually lands on a reef deposit.
[2] Scolymia cubensis like to settle on reefs that have steep angles to more easily dispose of sediments that get caught around their oral disks.
Once at the edge of the oral disc, their mouth will periodically ungulate or move in and out to shake off the sediments.
The sediments when being gathered for disposal are moved downward towards the part of the oral disc that is most downslope; so they also have the assistance of gravity to help them out.
[6] In Jamaica, S. cubensis engage in interspecific aggression with Scolymia lacera over light and space but are outcompeted by the latter.
