What is so special about coral reefs in the Arabian Gulf?
In the Arabian Gulf, situated in a hyper-arid area with relatively low biodiversity on land, the coral reefs of the region are the biological treasure chest housing most of the region’s biodiversity. In many areas, this biodiversity is considered key to finding new medicines for the 21st century.
What is coral reef system?
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.

What shapes coral reef communities across the GBR?
Fundamental variation of processes such as wave energy and sedimentation, also shape coral reef communities across the GBR and also partly explain the differences in the composition of benthic (substrate) communities across the continental shelf.
What are the three types of feeding in corallivorous fish?
There are three main feeding modes amongst corallivorous fishes: polyp-feeders, mucous-feeders and skeletal-feeders. Polyp-feeders use their forceps-like mouths to remove individual coral polyps, but do so without damaging the underlying coral skeleton (Cole et al.
