'Garden of sea fans' at Changi growing lush

A tiny team survey this 'reefy' part of Changi. It was a relief to see the 'garden' of sea fans are still present here and seem more lush than on our last survey in Apr 2025. 

Corals, anemones and other cnidarians seemed alright. And the team spot a variety of interesting marine life!

Greater Sentosa Master Plan unveiled

Sentosa’s beaches would undergo "rejuvenation works", including strengthened coastal protection measures. The rejuvenation project will enter its first phase with the construction of a transport hub linking Sentosa and Pulau Brani in Keppel Harbour. The timing of this phase has yet to be decided. 

Sentosa Development Corporation will soon launch design consultancy tenders for some of the key components of the master plan. Once completed, Greater Sentosa is projected to attract about double its current number of visitors, now about 17 million visitors a year.

These transport hub plans are very close to the last remaining wild reefs at Serapong shores - among the best near the mainland. Here's what the team saw on our survey of this shore last month.

The tiny team surveys on a short tide window this humungous submerged reef near the ongoing reclamation at Pulau Sudong. Water remains clear and the shore was alive. 

It was a relief to see the seagrass continuing to recover, with signs of dugong feeding trails! Corals seem okay and the rest of the team make all the special finds: sharks, giant clams, fields of branching corals and other colourful marine life.

Leathery soft corals continue to dominate some parts of this shore! We had a glimpse of a large Yellow lipped sea krait, possibly a Nurse shark, and a sea turtle. Also lots of tiny 'Nemos', a huge cushion star. The Clam team found 3 clams!

Other intertidal surveys: Apr 2026

Thanks to team members for checking up on other shores in April. Richard Kuah checked out Coney Island and saw beautiful jellyfishes, many carpet anemones, some with small cardinal fishes swimming very close to them - using the anemones for protection? And many other interesting marine life. Rui Quan Oh and friends checked out Sentosa and saw healthy seagrasses, many small creatures including some pretty fish. Marcus Ng checked out Changi Point and shared beautiful photos of octopuses (so glad they are back), many kinds of sea stars and other echinoderms, colourful flatworms and more. See their full albums below.

Rui Quan Oh and friends also checked out Pasir Ris mangroves and Pandan mangroves. So lovely to see snakes, insects, colourful and special crabs. As well as the Mangrove snake-eel and other fishes. Rui Quan also found four pipefishes under a rock! See his albums below.

Revamp of Giant clam conservation in Singapore and the region

Dr Neo Mei Lin hopes to have long-term conservation funding in Singapore, and plans to revamp giant clam conservation projects here and in the region.

The two giant clam species found in Singapore are threatened not by poaching but by habitat degradation and sediments on reefs. They are also widely spread across the reefs, limiting reproduction. “The numbers are so low that they’re not able to reproduce with each other,” noted Dr Neo.

In 2011 to 2018, Singapore bred giant clams for repopulating. But in one experiment, which involved putting 144 clams into the sea, only 29.9 per cent of them survived after 145 days. The aim is to ensure that the restocked clams can spawn and have their new larvae settle on the reefs and grow, forming the next generation.
