Like at Chek Jawa yesterday, most of the rubble at Pulau Sekudu look like this. Just a sprinkling of sponges or none at all. Most of the rock was covered by a variety of seaweeds.
Jun 2014 which was worse than in Aug 2013. The most common sponge was Melted chocolate sponge, the dark rose pink sponge that I have yet to figure out, and Yellow bumpy sponges. There were clusters of Yellow horn sponge, some Golf ball sponges, Spiky ball sponges in various colours, many Chocolate sponge, as well as clumps of black sponges. I didn't see any Purple branching sponge.
Posy anemones, the most abundant sponge were Yellow bumpy sponges. There were also a few clumps of Button zoanthids.
Reef octopus that appears to be clutching something in its arms at its burrow. There were lots of Swimming crabs of various kinds. I also saw a Red egg crab and a Maroon stone crab.
Knobbly sea stars in deeper water. The rest of the team also saw more Knobblies. The most abundant sea star on the shore were Biscuit sea stars.
feather star in deeper water, the rest of the team found more. I missed them but Marcus saw the Diadema sea urchins that usually encounter here.
Tiny ring coral, a kind of Favid coral. I saw many small patches of Zebra coral, but I didn't come across the Boulder pore corals that I saw in Jun 2014, but Kok Sheng saw some.
Miliaris cowrie and several Onyx cowries. As well as the usual cowries. There were also some Noble volutes on the seagrass meadows. The rest of the team found many different kinds of nudibranchs and Kok Sheng found a lot of flatworms.
Flat branch sea fan and two Skinny sea fans. Kok Sheng and the rest of the team saw more.
Jun 2014, the lagoon is still sandy and mostly bare although there are sprinkles of seagrasses and many Haddon's carpet anemones here and there. Where is the sand coming from?
Serrated ribbon seagrass patch is still there, growing among lush Spoon seagrasses. The area here has become super soft. I didn't see it, but the rest of the team found Tape seagrass with leaf blades that were rather long (about 30-40cm) but appear cropped at the ends.
Fern seagrasses, and abundant Haddon's carpet anemones. I did not see any anemones that were bleaching. Today, there were also a lot of large Swimming anemones among the seagrasses and some White sea urchins. I only saw a few Flowery sea pens.
Fan clams sticking out of the ground. Many of those sticking out that I checked were dead. Perhaps the live ones can dig down into the ground? Even dead, the empty shells provide shelter for small animals and a place for encrusting creatures to grow.
Aug 2013 but they recovered in Jun 2014.
Hollow-cheeked stonefishes. Kok Sheng shares more underwater photos too.
Pulau Sekudu means Frog Island and there is indeed a huge rock in the shape of a frog on the island. Someone had helpfully added eyes and a smile on the rock. There is a legend about an elephant, a pig and a frog and how they formed Pulau Sekudu and Pulau Ubin. More here.
Emperor, one filefish and two Eel-tail catfishes. In another, I released a large Copperband filefish.
Dr Chua Ee Kiam as we reminisce and chat at the end of our trip. Dr Chua is writing another book about Pulau Ubin! Salute! I can't wait to read it!
Chek Jawa Wetlands that is managed by NParks.
requires special permission from NParks. Thanks to NParks for permission and support to do these predawn low spring tide surveys of Chek Jawa. Thanks also to Chay Hoon for making all the transport arrangements. And the team for helping to cover as much ground as we can during the narrow low tide window. Thank you!
Chek Jawa and Pulau Sekudu may be affected by the 2030 landuse plan by the Ministry of National Development. The plan includes plans for a road link (black line) from the mainland jumping off at Punggol, crossing to Pulau Ubin through Chek Jawa to jump off to Pulau Tekong before circling back to the mainland on Changi East. Proposed reclamation (in yellow) will bury Pasir Ris shores, Pulau Sekudu and Chek Jawa as well as a large amount of shore at Changi Beach.

We probably won't be back to visit Chek Jawa and Pulau Sekudu until next year. I hope these unique and beautiful shores remain well until then.
