Today, I saw much fewer colourful sea cucumbers than in the past, with a more or less equal number of Pink warty sea cucumbers and Thorny sea cucumbers. There were also many medium sized Haddon's carpet anemones. It was nice to many large White sea urchins. The shore is still lively with lots of Orange striped hermit crabs of various sizes. There were many large Fan shell clams, which provide a hard surface for sponges, and other animals to cling to. When they die, the clam provides shelter for crabs. and small animals.
Knobbly sea stars and other sea stars and echinoderms. Kelvin saw two snake-eels! Which we first started to see on Changi in 2021. Although we didn't see any octopuses, Kelvin saw a cuttlefish and cephalopod eggs. The usual little fishes, crabs were also seen. As well as slugs of all kinds. Check out their album for their photos.

Aug 2020, horse mussels still dominate the shore at the low water mark and below. We first noticed this during our Feb 2019 survey and the clams were still there in Aug 2019 and Nov 2019. The patch is about 15m by 15m in the middle of the intertidal area exposed at about 0.1m. There is hardly any seagrass growing among the mussels.
Jan 2021, which was similar to the situation in Aug 2020 and Nov 2019. Nearer the high shore, there were dense growths of Spoon seagrass with small and large leaves, as well as Needle seagrass with narrow leaves. I only saw very few Fern seagrass today. There were also many patches of Needle seagrass with broad leaves, which I first observed in Feb 2019. The small patch of Smooth ribbon seagrass near the high shore is still there, and I also saw some Noodle seagrass which I first saw in Aug 2018.
What is the fate of these shores?
There doesn't seem to be a change in 2013 plans to reclaim all of Pasir Ris, all of Changi from Carpark 1 to Carpark 7 and beyond, and reclaim Chek Jawa and Pulau Sekudu. These appear to remain in place in the Long-Term Plan Review. Including plans for a road link that starts at Pasir Ris, crosses to Pulau Ubin, right across Chek Jawa to Pulau Tekong, and back to the mainland at Changi East.
See Changi shores for yourself before it's gone!
They are easy to get to, and enjoyed by many people. But it remains rich in a variety of marine life. More details in "Changi - an easy intertidal adventure for the family".
