Under the full moon, a small team checks out Sentosa's natural shores at Tanjung Rimau. It's the last few days of predawn low spring tide for the year!
There is still a bloom of Bryopsis seaweed. This is not normal. Usually, around this time of the year, the Sargassum seaweed bloom replaces the Bryopsis seaweed. I wonder what is going on. But as usual, this bloom is teeming with life. There were lots of little Reef octopuses slitthering through the Hairy green seaweed.
Bryopsis sea slugs. These slugs suck the sap of the seaweeds and eventually look like the seaweeds in shape and colour!
Arrow-head crab had stuck Sea grape seaweeds on its head!
amphipods (body flattened sideways) and isopods (body flattened downwards).
Little red-nose shrimps, as well as small snapping shrimps and little hermit crabs.
Blue-lined flatworm and Blue-spotted flatworm.
bristleworms of all sizes, squirming through the seaweeds.
Mosaic crab, the most poisonous crab in Singapore! I also spotted one Red egg crab.
swimming crab and a False scorpionfish (top right corner).
Haddon's carpet anemone has a pair of Five-spot anemone shrimps, the mama shrimp is bigger and more boldly patterned than the papa shrimp.
Tiny carpet anemone shrimp in the same anemone as the Five-spot anemone shrimp!
EcologyAsia website has lots of info about lizards and geckos of all kinds. But I'm not too sure what this is. Thanks to Marcus Chua who confirmed that it is the Maritime gecko!
Toothed top shell snail with its body showing. It also has fine lines, somewhat like the Nerite snails.
mass coral bleaching event in 2010. So I was glad to see that there wasn't much bleaching today, and that there were many small coral and leathery soft coral colonies in the short stretch of shore that I checked. I saw many small colonies of Pore corals and they were all nice and brown. I only saw one small colony of Disk coral and while it was not bleaching, it didn't look very healthy either.
Favid corals. And I only came across two that were partially bleaching.
Leathery soft corals of various kinds. Only one was somewhat bleaching.
Sickle seagrass! Although Siti reported seeing this species on Sentosa in Apr 2012, this is the first time I'm seeing them for myself. The Tape seagrasses are all long and lush and not thickly covered in epiphytes.
Spoon seagrasses. Seagrasses provide shelter for small and young animals and are thus an important nursery in the sea.
Frilly sea anemones which are usually abundant on this shore. One animal we are glad NOT to see is the Stonefish. We have had a Stonefish incident one this shore before, so we are very careful when exploring this shore.
The long line of blue drums are still there. These are part of a floating 'security barrier' installed in 2012. I only managed to look at a few of those nearer the shore. Compared to Pei Yan's last check in Aug 2013, none of the drums are broken, and it appears they have been rearranged so that the drums no longer bash against the rocks. The line of drums are also straighter. Pei Yan has been documenting the changes and impact of these drums.
