There are some corals growing outside the seawalls that form the artificial swimming lagoons at St. John's Island.
Pore boulder corals I saw had large pale patches, especially the upper portions which are exposed at low tide. Some were bright yellowish or green.
Anemone corals were very pale, others were still purplish.
Small gonipora corals that seemed alright, but a small one was rather green.
Flowery disk corals that were very yellowish, but also one that was a normal dark pink.
Cauliflower coral and it was ok, also one Sandpaper coral, it had whitish edges. Other corals that I saw that seemed ok included Plate montipora coral, Tiny ring coral, Galaxy coral and a small Mole mushroom coral.
Favid corals. I saw some with white or yellowish patches.
Sea mat zoanthids were mostly nice and brown with only a few colonies that were rather pale, but not yellowish or white. Jonathan took photos of leathery soft corals and they seemed ok, not bleaching.
Frilly sea anemone and Haddon's carpet anemone.
Razorfish. This flattened fish with a long snout swims head down and has a spine-like tail that can bend.
Honey-head damsel and Threespot damselfish.
Jorunna funebris nudibranchs today. This one seems to be crawling over to the blue sponge which it is said to feed on.
Starry mouth nudibranch. This odd looking creature has a pair of 'hands' near the front end. The sausage-like things on its long slender body enclose its feathery gills.
Common sea stars in the sandy swimming lagoon. At low tide, they are buried just beneath the sand, leaving tell-tale star shapes on the surface.
Spoon seagrasses (with small leaf blades) in both swimming lagoons. Jonathan has a photo of Tape seagrass that is nice and long (not cropped).
fiddler crab that was trying to stay immobile among the seagrasses.
Slender sea pen! Something I usually see in the seagrass meadows on our Northern shores.
Haddon's carpet anemones and most of them had a pair of anemone shrimps in them.
Galloping sea star. The tips of its arms were rotting away. I also saw a dead shell of a Sundial snail.
Fortunately, I didn't see any obvious signs of the oil spill that landed on St. John's Island five months ago in Jan 2014.

NEA recently issues an advisory that ""Rainfall for Singapore between June and September 2014 could range between 10 - 40% below average, while the average daily temperature is expected to be about 1°C above average". Such conditions can trigger mass coral bleaching.
Let's hope our corals make it through the weather ahead. The team will be trying to survey as many shores as possible during this period to keep an eye on things.
