There are astonishing reefs at Sentosa Serapong! For the first time, we visit during a super low spring tide well before dawn.
The most astonishing animal spotted, I saw only when I got home! I didn't notice that this red feather star has the white commensal brittle star (Ophiomaza cacaotica) in it! I've only seen this once before at Raffles Lighthouse.
Acropora corals (Acropora sp.) that he saw on our last trip! Indeed, many of the corals on this shore are large and well-grown.
leathery soft corals (Family Alcyoniidae) of all kinds here.
Tuas, with plenty of flowery soft corals (Family Nephtheidae) and Button zoanthids (Zoanthus sp.). I even saw the nasty stinging hydroids that are very common on Tuas as well.
Cauliflower corals (Pocillopora sp.). Some of the colonies were quite large. Many of them had a pair of bright red crabs (Trapezia cymodocea) that live only in these corals. Kok Sheng and Marcus also got photos of some interesting coral commensals.
Acropora corals (Acropora sp.) here. This coral is rather delicate and is seldom found so close to the mainland!
Galaxy coral (Galaxea sp.) because of their structure and they are often quite colourful.
boulder-shaped sandpaper coral (Psammocora sp.), encrusting horn coral (Hydnophora exesa), an encrusting horn coral. I also saw a small Carnation coral (Pectinia sp.).
Disk coral (Turbinaria sp.) of various kinds.
Mole mushroom corals (Polyphyllia sp.). Marcus also saw some other mushroom corals.
mass coral bleaching.
Favid corals (Family Faviidae) are abundant. There were also Pore corals (Porites sp.), large colonies of healthy Anemone corals (Goniopora sp.), a few patches of Small Goniopora corals (Goniopora sp.), some large Sandpaper coral (Psammocora sp.), a few Brain corals (Family Mussidae), and some branching Montipora corals (Montipora sp.). Kok Sheng also came across some Anchor corals (Family Euphyllidae). I missed seeing the Ridged coral (Merulina sp.) and Lettuce coral (Pavona sp.) that I saw on our previous trip last year.
red feather stars (Class Crinoidea) clinging onto the large Montipora corals (Montipora sp.) and other corals on the shore.
Magnificent anemones (Heteractis magnifica before the tide turned. There must be about 10 of these large sea anemones there, and every single one of them were full of Clown anemonefishes (Amphiprion ocellaris). I only managed this feeble shot of some small anemonefishes. Kok Sheng got a great shot of a larger fish. There was also a Giant carpet anemone (Stichodactyla gigantea) in the area.
Bengal sergeant (Abudefduf bengalensis), some kind of wrasse (Family Labridae), and a toadfish (Batrachomoeus trispinosus).
Ornate leaf slug (Elysia ornata), Phyllidieila nigra. Shao Wei found a pretty purple spotted flatworm (Pseudoceros laingensis). She also found a Synaptid sea cucumber (Family Synaptidae) and lots of other reef creatures too!
Barrel sponges (Xestospongia testudinaria) here!
Tape seagrass (Enhalus acoroides), Marcus saw Sickle seagrass (Thalassia hemprichii) while Kok Sheng found some Spoon seagrass (Halophila ovalis).
All too soon it was sunrise and the tide really turned. The golf course siren also sounded the alarm for incoming weather, so we had to leave. (The alert is quite accurate as it started raining soon after we left!)
