The visibility is good today and we could see more bleaching right at the jetty.
NOAA's coral reef watch satellite monitoring,Singapore is in the yellow Watch zone. Where we should be prepared for mass coral bleaching.
What is coral bleaching?
Coral are colonies of tiny animals called polyps. Each polyp lives inside a little hard skeleton. The huge colony is made up of the skeletons of countless polyps. The polyps of all reef-building hard corals harbour microscopic, single-celled algae (called zooxanthellae).
Circular mushroom corals I came across were not bleaching, although one had pink patches, a sign of stress.
Anemone corals I saw were alright although I did see one small colony that was bleaching. I only saw one small colony of small Goniopora coral and it looked bleachy.
brain corals I saw were bleaching, some had spectacular colours. I saw few small disk corals, a few Flowery disk corals which were bleaching.
Cauliflower corals and they were somewhat pale. I saw several Crinkled sandpaper corals and most were alright except for a few small colonies that were very pale. I saw many plate Montipora corals that were bleaching, but didn't come across any branching corals from the Acropora family. I also didn't see any Galaxy corals.
Carnation coral, Ridged plate coral. Today, most of those I saw were bleaching, except for Lettuce corals. I saw two small colonies and both were alright. I could not find the large colony of Anchor corals that was there on our last survey in Aug 2015.
Boulder pore corals were bleaching. Most of them were alright or just a little pale or pinkish. Many of the Merulinid corals (previously Family Faviidae) were alright, even those growing on the seawall. But some of large colonies were bleaching.
leathery soft corals were bleaching. I didn't see any flowery soft corals.
Pizza anemone and three Bubble tip anemones. But no anemonefishes.
Giant carpet anemones and all but 3 of them were alright. Many of the anemones had clown anemonefishes, as well as anemone shrimps. I also saw several Haddon's carpet anemones, some had shrimp and none were bleaching.
Frilly sea anemones I saw were bleaching.
Smooth frilly sea anemone might be some other kind of anemone species. I saw two today and both were bleaching.
Button zoanthids, and about 50% of the Sea mat zoanthids were very pale or bleaching. I also saw a few bleaching Fine feathery soft corals.
corallimorphs, although most of them were alright.
The small ring of Tape seagrass in the small lagoon was still there. The leaf blades were rather short. There were sprinkles of Spoon seagrass here and there.
So nice to see a group of school kids doing biology training on the shore. We need more people to learn about our shores and work to protect them!Marine Park and managed by NParks.
