After a rain storm, we survey the large expanse of Changi's seagrass meadows during a super low tide. The seagrasses are lush and thick. We saw lots of dugong feeding trails!
300-tonne oil spill in the East Johor Strait in January. I didn't see any signs of oil today and was glad to see many of the usual animals.
Dugongs eat seagrasses (and hence sometimes also called sea cows). They leave a typical trail when feeding in a seagrass meadow. A band of bare sand of equal width, somewhat meandering. There were many such trails visible today in the very low tide.
Spoon seagrass (large and small leaved) with some Needle seagrass (mostly narrow, but I saw a few clumps of broad leaved ones) and some patches of healthy looking Fern seagrass. I couldn't find the patch of Smooth ribbons seagrass, but they might still be there, I just overlooked them.
filefish that looked just like a seagrass blade, and a small solefish.
As usual, the most abundant animal on the seagrass meadows are sea cucumbers. Dominating the shore were many Thorny sea cucumbers and Pink warty sea cucumbers. There were also many Orange sea cucumbers, some Purple sea cucumbers. I saw one small Garlic bread sea cucumber and a Smooth sea cucumber and a few Ball sea cucumbers.
Knobbly sea stars. There were many tiny to small Biscuit sea stars. I saw one Common sea star.
White sea urchins (I saw about 10 small to medium sized ones), many Flat-armed brittlestars and I saw one feather star.
Haddon's carpet anemones on the shore.
Swimming anemone, one Big hermit-hitching anemone, some Tiger anemones, one Mini carpet anemone. Dr Sergio was with us and fortunately we found a few cerianthids that he found interesting. But this shore doesn't have many of them.
Orange-striped hermit crabs, a few Flowery sea pens, some Acorn worms. And many clumps of these lacy white things. I'm not sure what it is.
Noble volutes, but did see one of their egg capsules that looks like the babies had hatched. There were many Hammer oysters. I saw some pink egg strings but couldn't find any sea hares. The only slug I saw was an Ornate leaf slug.
Clear sundial snail, which we have seen only in the South so far. I saw one today, laying eggs.
We had planned to survey the seagrass meadows at Changi Point. But we got word that a huge excavator was seen yesterday ripping out old pipes there, probably causing extensive damage to the shore. Marcus and Kok Sheng checked it out today and saw many injured Ball sea cucumbers. These sea cucumbers are usually buried.

On 28 May, Loh Kok Sheng and some of the team visited this shore at Changi and saw some awesome marine life! Jianlin Liu and Jesselyn Chua were also on the trip.
Victor Toh was also at Changi. And saw traces of oil in his footprints.
On 31 May, Chris Wong surveyed Changi bay next to the Ferry Terminal and shared what he saw.
