This morning, I saw lots of huge Eight-armed Luidia sand stars at Changi! My first time seeing this.
The sea stars were very large! My foot next to one for scale. I stopped counting after I saw 30 individuals. I saw them at the point which seems to now be mostly bare sand. I only counted those I could see on the mid shore, there are probably many more in deeper waters. I'm not sure why there is such a large number of them.
These sea stars can move quickly and some were quite active, flailing their arms and 'walking' quickly on the sand. They are predators. So there must be a good source of their prey for there to be so many of them in such vigorous health.
Pink warty sea cucumbers and some Thorny sea cucumbers. I saw a few Sea apple sea cucumbers, Garlic sea cucumber, Ball sea cucumbers. I saw several large White sea urchins, widely scattered. I didn't see many sea stars: a few tiny to small Biscuit stars, in the sandier areas, a few Plain sand stars. I didn't see any Common sea stars. During our last survey in Jul 2018, we saw lots of feather stars and Black sea urchins. I didn't see any today.
Common cerianthids, some small and large Haddon's carpet anemones, on Big hermit hitching anemone, one Common peachia anemon. But no Tiger anemones. I saw many Sea Pencils, and some Flowery sea pens. I didn't come across other kinds of sea pens. I also saw one small Ball flowery soft coral.
Mangrove horseshoe crabs. On our last survey in Jul 2018, we saw many more.
Big-head seagrass octopus. It was hiding in a broken glass bottle. Unfortunately, these creatures are heavily harvested by fishermen for bait. This morning, there were four people out with buckets and a headlamp slowly searching the shore. We didn't get a chance to chat with them to find out what they were collecting.
Feb 2019. Although there were some Fan clam shells, they were small and scattered. There were some thin sheets of Little black mussels on the rocky areas. I saw two Calf moon snails, a Hairy sea hare and a Spotted sea hare.
Jul 2018. The meadows were mostly Spoon seagrasses (large and small leaf blades) with scattered and patches of Needle seagrass (narrow leaf blades). I didn't come across Fern seagrass. The small patch of Smooth ribbon seagrass where the pipes used to be are still there, first observed on our Jun 2016 survey. But I didn't see clear dugong feeding trails today.
Zebra corals on all the rocks on the lower shore.
Atagema intecta (black blob near black sponges - does it eat the sponge?) and a well camouflaged Thordisa villosa - spotted by Shawne, Bravo!
