There is a lush seagrass meadow at Changi. We quickly surveyed it during breaks in stormy weather, and found it was still very much alive.
Jonathan found one baby Knobbly sea star!
Painted sand star and a few tiny Biscuit sea stars.
Pink warty sea cucumbers were the most abundant sea cucumber on the shore. There were much fewer Thorny sea cucumbers. We also saw some Smooth sea cucumbers, Ball sea cucumbers and a Purple sea cucumber.
Cake sand dollars on the sandy slope above the mid-water mark. A strange place to find them. I didn't come across any sea urchins.
Tiny carpet anemone, and one tiny cerianthid. I didn't see any seapens or any large Haddon's carpet anemones.
Noble volutes on the shore. This one appears to have 'caught' something. These snails eat buried bivalves and engulf them with the humungous foot.
Gong-gong, most of them quite young. I suspect the 'older' ones have been harvested by people. There were also a few Large cockles, some medium sized Fan shell clams. I saw many shells of Big brown mactra clam but no living clams.
Window pane shells. This one was coated in Green gum drop ascidians, and had a Big hermit hitching anemone on it. There were also many Orange striped hermit crabs.
Surf clams which live in the surf zone. Probably, there are a lot more buried safely in the sand. The high shores were dotted with the burrows of Ghost crabs, although we didn't see any of the crabs, probably due to the rainy weather.
Green gum drop ascidians dotting the seagrass blades.
Spoon seagrass I saw was heavily coated in ascidians. Mostly Beige sheet ascidians.
Smooth ribbon seagrass. Our first sighting of this at Changi. At first I thought it was just broad Needle seagrass, but fortunately, Jonathan took a closer look. There were also large areas of Needle seagrass with narrow leaf blades. I didn't see any Fern seagrasses in the small area that I surveyed. But they may be present in deeper water.
Slender pom-pom seaweed dotting the seagrasses.
predawn Sumatras hit the shore. But I managed to do a quick survey of a small portion of the shore before the storm hit, and again later after it passed and before the tide turned.
Jonathan Tan was also on the trip.
