yesterday, this one was also very quiet. But we did see Knobbly sea stars and a pair of otters!
The seagrasses were doing very well, covering almost all the intertidal with few sandy patches even on the sand bars. Mostly Needle seagrass with narrow leaf blades and Spoon seagrasses. I only saw small patches of Fern seagrass. I didn't come across any dugong feeding trails today. Our last trip here was in Jul 2015 when I already noticed that this shore has changed and we no longer see many of the creatures that we saw in Jun 2013.
Knobbly sea stars. It appears, we all separately saw different individuals. We saw Knobblies on our trip here in Jun 2015 and Jul 2015. Is Changi changing and now becoming sustainable for a Knobbly sea star population? But today, I saw only one Painted sand star and one tiny Biscuit sea star. I didn't see many brittlestars, although there is one on the arm of this Knobbly sea star. While we saw plenty of them in Jul 2015, today I saw only one White sea urchin.
Hammer oyster, Window-pane clams (some quite large), Big brown mactra clams and small young (shells were thin) Fan shell clams. I saw several Black-lipped conch snails but few live Gong gong. I didn't see any slugs today. I saw a few large Haddon's carpet anemones. They had lots of tiny anemone shrimps. I didn't see any cerianthids and I only saw a few sea pencils,
Orange striped hermit crabs, some of them were quite large. I don't quite know what these three were up to.
swimming crabs and sea cucumbers. The fluffy thing on the left corner is not algae, it is a fish!
Pink warty sea cucumbers were the most abundant sea cucumber on the shore. There were much fewer Thorny sea cucumbers.
Purple sea cucumber, one small Garlic bread sea cucumber, a few Ball sea cucumbers, and some Orange sea cucumbers like this one.
Mermaid's fan seaweed. Among them, I saw this Variable fang-blenny. As its name suggests, it can give a really nasty bite.
Mexican feathery green seaweed. Among them were tiny fishes like these gobies.
filefish that looks just like a seagrass leaf blade. I didn't see any of the fluffy red seaweed/cyanobacteria that we saw yesterday at another part of Changi.
Mitre snails that we first started to see here only in 2012. At first I thought the snails were eating something.
