knee deep. Corals that grow in this area flat, short, and have settled on boulders. |
Sarcophyton ehrenbergi species that are on Heron Island Reef can be found on the inner sandy reef flat. In the sandy area, rubbles and boulders of dead coral can be found that have been colonised by other organisms such as corals, sponges, and even algae. The dead coral boulders provide a new foundation for organisms which have settled on them, which further attracting cryptic, sedentary, and pelagic organisms.

Sarcophyton ehrenbergi were found. (Image taken from maps.google.com) |
Specimen for study purposes were collected from the south side of Heron island (pic 2). Specimen was found growing on a boulder that was half submerged under the sand. Retrieving of boulder with leather coral required some digging. Some leather corals can be found on large boulders that require breaking with a hammer and chisel.
Pic 3 Small piece of dead hard coral found amongst the boulders on
the reef flat. Many sessile organisms have taken over various places
of the dead coral, each competing for space. A: Small colony of
Sarcophyton ehrenbergi growing on the side of the dead coral.
