|Coral bleaching with dead rotting grey tops.|
It was heartbreaking to see that most of the large Boulder pore corals were badly affected.
Cauliflower corals were bleaching, next to colonies that died long ago and were already covered in epiphytes.
Disk corals were also bleaching or dead or dying. Some in deeper water were alright, and small ones on higher ground seemed alright.
Anemone corals on this shore. Here's Abel next to one of the several colonies found here.
Sandpaper coral had large portions that appeared dead, and a few Acropora colonies that I saw were bleaching or dying or dead. But Kok Sheng saw a large field of healthy Branching montipora corals further up the shore.
Merulinid corals were mixed. Some large colonies were alright, others were bleaching or dying.
Lettuce coral, Carnation coral, Galaxy coral, Anchor coral, Trumpet coral and Brain coral.
Ridged montipora corals, only the top parts exposed at low tide appear to be dead. With the portions that are submerged not as badly affected.
leathery soft corals situation was mixed. Some had large holes, which I notice tends to happen as the colony is stressed - breaking up into smaller portions may increase the chances of at least one portion surviving. Some colonies were very flourescent, others had large patches of peeling scummy layers.
Leathery sea fan that was dying at the base, but other sea fans at the old jetty seemed fine. I saw many Asparagus flowery soft corals and bluish Broad feathery soft corals that were alright. But I didn't come across any other flowery soft corals that used to be common here. I saw some zoanthids that seemed well.
Frilly sea anemones that looked fine, as well as some Magnificent anemones, many with small anemonefishes. I even came across one Fire anemone. And Kok Sheng saw a Leathery sea anemone.
Barrel sponges were badly affected.
Fluted giant clam that was rolling in the waves, not fixed to the ground. It otherwise seemed alright. There were also still many Red feather stars. The rest of the team also saw nudibranchs, a large seahorse and other interesting marine life.
Spoon seagrass (with small leaf blades). The patch of Sickle seagrass appears to be thinner than before. And we saw one clump of Tape seagrass with long leaf blades and female flowers.

It's a mystery to us what has caused this, but it appears to be limited to the Serapong shore. Abel checked with Lena who visited Sentosa Tanjung Rimau shore a few days ago and Lena said she did not notice anything untoward. We also didn't see anything this drastic during our recent surveys of reefs near Pulau Semakau.
Let's hope this shore recovers soon from whatever is affecting the corals.
Thanks to Annabelle and Shao Wei of Sentosa Development Corp and Sheila of Serapong Golf Course for arranging our survey this morning.
