[2] It occurs on reefs in shallow waters in the Red Sea, off the coast of East Africa, and in other parts of the tropical Indo-Pacific.

Its western range includes Mozambique, Madagascar, the Seychelles, Réunion, Mauritius, Aldabra and Chagos.

[1] It is found on upper reef slopes and is common in some localities, but less so than the closely related Lobophyllia hemprichii.

[2] When young, Lobophyllia corymbosa is a colonial coral with a layer of living tissue covering the skeleton and connecting the polyps.

This experiment showed that the polyps were not only able to recognise clones (even when they had been experimentally separated from them for years) but were also prepared to "help" them when they needed assistance.

It is not clear if the transport of nutrients between the polyps is made by the transfer of blobs of mucus or whether it depends on the active movement of migratory cells.
