|Oil spill on this shore in Jan 2017.|
In the past, many of the stakes have been uprooted from the high shore and littered all over the low shore. As the stakes move in the waves, they are probably also killing any seagrass or animals that attempt to settle there. A blog post by Jocelyne Sze on this setup in 2014 showed it was still okay. I observed it falling apart in Apr 2015, again in Aug 2016. This is what I saw on our last trip here in Dec 2017.

Blue feather stars. Some on the jetty legs, others dispersed among the seagrasses.
Thorny and Pink warty sea cucumbers remained the most abundant. As well as Ball sea cucumbers. I saw two Sea Apple sea cucumbers, a few Beige sea cucumbers and one Plasticky sea cucumber and one large Garlic bread sea cucumber.
Cake sea star, one medium sized Knobbly sea star and many Biscuit sea stars. I didn't see any Painted sand stars or Plain sand stars.
White sea urchins, many carrying all kinds of stuff. I also saw one small Black sea urchin and the dead shell of a Cake sand dollar, I couldn't find live ones.
Burgundy anemone, the first I've seen beyond Pasir Ris. I also came across one Brown peachia, which was described from Singapore! There were also some common Peachia anemones, a few Swimming anemones and some Haddon's carpet anemone. On the jetty legs, there were lots of Lined bead anemones.
Sea pencils, some Slender sea pens and Flowery sea pens, and one Spiky sea pen. But I didn't see any cerianthids, although we saw many here with Dr Stampar on May 2017.
Geographic sea hare! The rest of the team saw other interesting slugs too.
Wandering cowries, some Miliaris cowries and one Onyx cowrie. There were also many Drills laying eggs.
Calf moon snail and a Pink moon snail.
Rafting crab on the jetty legs, and one Maroon stone crab among the rocks. There were also some Purple climbing crabs and many Swimming crabs of all sizes and all kinds. On the seagrasses, there were many Orange-striped hermit crabs.
Fern seagrass, Spoon seagrass (with large leaf blades) and Needle seagrass (narrow leaf blades). But the seagrasses in the area in front of the new seawall appear to be gone. Hopefully, they will return.
