Clams have taken over most of a stretch of Changi beach, forming a dense firm mat.
It was alarming to see that much of the shore has been taken over by these clams. I don't know the identity of the clam, but I have seen this before on some of our other shores, though not in such dense mats. These do not look like the invasive clams that took over at Kranji.
Fan shell clams, similar in size, so perhaps of the same age?
Window pane shells. I did notice many small Fan shell clams and Window pane shells during our last survey in Aug 2018.
Noble volutes, some Gong gong and Black lipped conch, one Miliaris cowrie. Kelvin spotted the empty shell of a Baler snail, we saw a live one here on our last survey in Aug 2018. There were lots of egg capsules including some sand collars. I didn't see any live Babylon snails, but did see a shell occupied by a hermit crab.
Biscuit sea star and couldn't find the Common sea stars. I saw a few White sea urchins and Black sea urchins, all small. There were a lot of young Garlic bread sea cucumbers, and lots of Thorny sea cucumbers and Pink warty sea cucumbers. I saw one Ball sea cucumber. There were also lots of little elbow crabs, tiny Flower crabs.
Knobbly sea star.
There were also many Haddon's carpet anemones and I saw one Geographic sea hare. Here's a clip of some of the marine life on the shore.
Leaf porter crab under it!
Spoon seagrass, Fern seagrass and Needle seagrass with narrow leaves. For the first time, I saw a lot of Needle seagrass with broad leaves. But I didn't see the Smooth ribbon seagrass and Noodle seagrass that I saw during our last survey here in Aug 2018,

Meanwhile, Richard Kuah surveyed Coney Island on 18 Feb and the shore looks good.
