Sentosa Development Corp! We start at the sandy shore behind Underwater World and wow, there's a carpet anemone! The Haddon's carpet anemone (Stichodactyla haddoni) is commonly seen on shores like Chek Jawa.
Even though the tide was still high, there's stuff to look at and wonder about. On the high shore, we learn about the many different ways sea creatures suck up carbon. Besides hard corals, there are seaweeds too that incorporate calcium into their bodies.

Coin green seaweed (Halimeda sp.) that incorporates calcium.
swimming crabs (Family Portunidae) and Spotted moon snails (Ashtoret lunaris). In the pools of water, we saw many Cresent perch (Terapon jarbua). But I couldn't find any Common sea stars (Archaster typicus) that we used to see here.
On the rocky part of this shore, we saw some Purple climbing crabs (Metopograpsus sp.) and lots of Sea slaters (Ligia sp.) which were too fast for me to photograph. Under the stones, some small crabs including the Spoon pincer crabs (Leptodius sp.). On the rocks, some oysters (Family Ostreidae). Lower down on the shore, there were colonial anemones (Zoanthus sp.) and some Frilly anemones (Phymanthus sp.).
Today, there is a bloom of Hairy green seaweed (Bryopsis sp.) and some Sargassum seaweed (Sargassum sp.). But the bloom is not excessive. We also saw some Mermaid's fan (Padina sp.) and Neomeris sp. which was given a very good common name of 'Taugeh' seaweed! Seaweeds are a natural part of the shore and go through cycles of bloom and bust. They provide food and shelter for all kinds of animals. Here's some of the tiny creatures we have seen in Hairy green seaweed on Sentosa in the past.
Nyireh bunga mangrove tree (Xylocarpus granatum) has settled naturally! Hopefully, this seawall will attract natural settlement of many other kinds of mangroves, just like the seawalls at Pulau Hantu!
massive construction going at Berlayar Creek now for a new boardwalk there. In the sandy areas nearby, we saw one Cake sand dollar (Arachnoides placenta).
massive reclamation going on now for years for the new Pasir Panjang Container Terminal.
Tape seagrass (Enhalus acoroides). Although many leave blades were cropped to an equal length, they are long and mostly green and not burnt.
Spoon seagrass (Halophila ovalis) were not doing well at all! I came across patches of seriously bleaching seagrasses with the blades losing the green parts. Others had reddish leaf blades, and yet other patches had no leaf blades at all!
June 2010 at the height of the bleaching event. More about coral bleaching on Bleach Watch Singapore.
Montipora coral (Montipora sp.). On the reefs next to Rasa Sentosa, we saw some Favid coral (Family Faviidae), as well as Pore hard corals (Porites sp.) and Goniopora corals (Goniopora sp.).
Feathery soft corals, one small Leathery soft coral (Family Alcyoniidae) and a small colony of Blue coral (Heliopora coerulea).
Blue spatula sponge (Lamellodysidea herbacea), Yellow pot sponge (Rhabdastrella globostellata), Daisy sponge (Coelocarteria singaporensis) and Blue jorunna sponge (Neopetrosis sp.).
Sea Teak (Podocarpus polystachyus) which is abundant here. This curious tree is a pine or conifer! Although it produces seeds, it has no flowers. Instead, it has reproductive structures called cones. Male cones (left photo) and female ones are found on separate trees.
Nyireh tree (Xylocarpus rumphii). With a younger one nearby. These trees are listed as Critically Endangered. As far as I know, these mangrove trees are only found on Sentosa and St. John's Island.
Tongkat Ali (Eurycoma longifolia). This plant is famed for its purported aphrodisiac properties, which sadly leads to over harvesting.
Delek air (Memecylon edule) . It's starting to bloom! This tree is famous on Chek Jawa.
Nepenthes rafflesiana) scrambling on this coastal forest. The pitchers are modified leaves and contain a substance that can dissolve hapless insects that slip and fall into the pitcher.
Jejawi figs (Ficus microcarpa) that were figging! Joseph Lai did a survey of this forest in July 2006 and shares a long list of the many plants found here.
Ivan in 2010, who had to stay in hospital for days! Here's more about the horrible Hollow-cheek stonefish (Synanceia horrida), which I encounter all too often. My most recent being just a few days ago at Tanah Merah. But this is the first time I've encountered one on this Sentosa shore. Oh dear.
I just heard from Grace that Shao Wei has been discharged from hospital. What a relief! Hopefully, this means her encounter was a mild one and that she will have a speedy recovery!
More about this natural Sentosa shore. Thanks to Shao Wei and other friends, recently I also managed to see other interesting parts of Sentosa such as the rare mangrove trees at Serapong and a glimpse of the reefs at Serapong.
