Here's a glimpse of what I saw, on this pretty little island just half an hour from the Central Business District on mainland Singapore, and near major shipping lanes.
Pore boulder corals, some had pink or pale patches, suggesting that they are not quite well.
Merulinid corals were had pale to white patches.
Sandpaper corals that seem to be doing well. I also saw Branching montipora corals and one small Acropora coral. As well as one Galaxy coral and many small Anemone corals and some Disk corals. I saw many Circular mushroom corals but couldn't take a nice photo of them. All were not bleaching.
leathery soft corals. All seemed alright.
Sea mat zoanthids that were very pale. There were many Frilly sea anemones, and some Giant carpet anemones, none were bleaching. And I found a large cluster of Ridged corallimorphs that eluded us on our Jan 2018 trip. The rest of the team saw lots of colourful flatworms, nudibranchs and other interesting marine life.
Jan 2018. There were lots and lots of Oval moon snails in the sand.
Spoon seagrasses with super tiny leaves sprinkle the sandy area here.
Tape seagrass in the small lagoon is still badly cropped. Some of the team saw Common sea stars here.
