There are living rocky shores and lush seagrass meadows at the mouth of Changi Creek, where bumboats ply to and from Pulau Ubin.
It was great to see colourful sponges of various kinds growing on the rocks in deeper water.
Bohol nudibranchs. The one I saw was clinging onto the rock. The rest of the team saw many other kinds of nudibranchs too. Check out especially Jianlin's album! People often don't believe me when I say that we often see a wider variety of nudibranchs on the Northern shores than among the reefs of our Southern shores.
Zebra coral and one small colony of Anemone coral. I saw one small Spiky flowery soft coral, some small sea fans of various kinds (but not as many or as large as those I saw on our last survey in Jul 2019). I saw a few Cerianthids and many Haddon's carpet anemones.
Noble volutes and some Gong-gong snails. There were a few small fan clam shells, some tiny Window pane shells and a Large cockle. It was a relief NOT to see Horse mussels, which have taken over some other parts of Changi beach.
Knobbly sea star. I saw several Biscuit sea stars large and small, several small Cake sea stars, several Eight-armed sand stars small and large. I also saw one Blue feather star.
Luidia sea star.
Pink warty sea cucumbers and Thorny sea cucumbers were the most common. We saw a few small Garlic bread sea cucumbers. There were also many Ball sea cucumbers in the sandy areas. I one Orange sea cucumber, and a Big synaptid sea cucumber wrapped around a sponge. We didn't come across any sea urchins.
Spoon seagrass (small leaf blades) all along the shore from the jetty onwards. But large patches of the seagrasses at the mouth of Changi Creek were bleaching.
Needle seagrass in the lower water mark, which I first noticed in Jul 2017. I didn't see any dugong feeding trails today.
Sea lettuce on the rocks at the mouth of Changi Creek.
Jul 2017, seven months after it was hit by the 300-tonne oil spill in the East Johor Strait. At that time, it was recovering very well. There was also massive coastal works on this shore to build the seawall in late 2018 to Jan 2019.
