Beting Bronok used to be full of amazing echinoderms. And today, the team saw four Bordered sea stars today! So far, we commonly see this star only on Beting Bronok.
Biscuit stars, a few small Cake sea stars, one Spiny sea star and one Scaly sea star. The rest of the team saw one Knobbly sea star. We saw five on our last survey in Aug 2015.
Smooth sea cucumber, one Ball sea cucumber and one Thorny sea cucumber.
Thorny sea urchins, and one blue feather star.
Beting Bronok often has lots of nudibranchs. Today I saw about eight of these fat Ceratosoma gracillimum more commonly seen by divers in reefs. I also saw two Discodoris boholiensis, while the rest of the team saw many 'Blue Dragons', like we did on our last survey here. Meanwhile, there were also many very large Spangled flatworms. Rene saw many Olive flatworms gathered together, and saw a total of 4 flatworm species.There were many octopuses on the shore, the one I saw was at its burrow. The rest of the team found two seahorses! I saw some gobies, a toadfish, filefish and rabbitfish. There were also some Swimming crabs.
Noble volutes laying eggs, and several small ones. There were also many Swimming anemones. I only saw one live Onyx cowrie, unlike on our last survey when we saw a lot. None of us saw the Baler snail. I didn't come across any living Fan shell clams.
NOAA's coral reef watch satellite monitoring shows that Singapore is in the Watch zone. Where we should be prepared for mass coral bleaching.
Spiky flowery soft corals.
Pink flowery soft corals and they were all not bleaching. Most were pink, some had paler body columns but bright red polyps. There were also many clumps of Knobbly soft corals. There were also many small clumps of various hydroids including Fern hydroids and the nasty Stinging hydroids. Also many Candy hydroids although most of them were heavily covered in epiphytes.
Ball flowery soft corals, one had White soft coral snapping shrimps. The colonies were mostly alright, although some were slightly pale.
Neat hexagonal coral that were alright. And two colonies of Big ring merulinid corals that were full on bleaching. I did not see any other Merulinid corals.
Branching pore corals. Most of them were brown, some were covered with a bluish slime, and one had a small bleaching patch.
Boulder pore corals were fully bleaching, 30% were pale or had bleaching patches. But 40% were still brown. The corals at Beting Bronok suffered badly from mass bleaching in 2010.
Candelabra sea fans, one small Tree sea fan and several Gnarled sea fans. Similar to the situation during our last survey. But I couldn't find any commensals on the sea fans.
Flowery sea pens and one Slender sea pen and two cerianthids. They were not bleaching. I did not see any Spiky sea pens.
Haddon's anemones. Some were very small, others were alright. Only one looked a little bleachy. I didn't see any anemoneshrimps. Nick saw several Haekel's anemones, and a Glass anemone.
Button zoanthids cover vast areas of the reef. I also saw a small patch of Sea mat zoanthids. I did not see any that were bleaching. I saw a sprinkling of Spoon seagrass while the rest of team saw larger patches.
Aug 2015. This is what the shore looked like today.

Where is Beting Bronok? What is it's status and future?

It was good to see that Beting Bronok remains alive and full of fascinating creatures. But to me, it seems to be in steady decline since the reclamation started at nearby Pulau Tekong . It has since also been affected by the flooding that led to mass deaths at Chek Jawa in 2007, and the coral bleaching in 2010 and a ferry ran aground on Beting Bronok in Jul 2011. Here's some old photos of marine life at Beting Bronok. We can only hope for the best for this wonderful reef on our Northern shore.
There are plans that may affect Beting Bronok a in the not too distant future. These include plans to locate at Pengerang Johor, a petrochemical complex that was rejected in Taiwan for environmental and health reasons.
