“The total landmass of the main island and surrounding smaller islands is approximately 650km2, though land reclamation is constantly increasing this figure. There are numerous patch reefs in the waters south of mainland Singapore and many of the small islands have fringing reefs.” (Study area, para 1)
“Chou (1988) surveyed four of Singapore’s southern reefs, including cyrene reef and Pulau Hantu which are studied here, and found between 25.3% and 62.0% live coral cover at 3m depth with a range of 15 to 28 genera.” (Study area, para 1)
“Raffles Lighthouse (Pulau Satumu), Located 15km from the main island of Singapore, Raffles Lighthouse is the furthest offshore of the southern islands.
Pulau Hantu is predominantly made up of land reclaimed in 1974 and the island is now used for recreational purposes. Although most of the original reef flats have been covered, the reef slopes are still intact. However, these were delteriously affected by sedimentation from the reclamation project and are still subject to sedimentation from similar work and dredging in the vicinity, making the levels here slightly higher than at Raffles lighthouse” (Study area, para 2,3)

The assistant curator was able to use the steam launch Shark during August, for the purpose of investigating the habits of a sea-snake common on the Raffles Light Island… Marine collections and a few kinds were obtained from the neighbouring islands.” “In addition numerous trips were made to various parts of Singapore Island to collect freshwater fishes, earthworms and land and freshwater molluscs. Pulau Renggis, near Blakang Mati, was twice visited; marine worms and two species of reef spider were obtained.

As late as the mid-1600s, the Riau Archipelago was still featured as a fantastic agglomeration of impenetrable islands on what was otherwise (or may be) a relatively accurate chart… A classic description of this maze of islets that make up the Riau Archipelago is found on a map virtually unknown to many contemporary experts on Singapore.
