What a delight to encounter this fish on oil-slicked Tanah Merah!
Eightband butterflyfish (Chaetodon octofasciatus), and usually only near reefs. But Kok Sheng had seen a group of them at Tanah Merah, among the corals growing on the outer seawalls.
My first sightings on this shore after the oil spill includes this large spotted black flatworm (Acanthozoon sp.) which is commonly seen on our other shores especially near reefs.
Brown spotted moray eels (Gymnothorax reevesii).
Hollow-cheeked stonefish (Synanceia horrida) is quite plentiful. Luckily I saw him before I stepped on him!
Painted scorpionfish (Parascorpaena picta). Above it, the bluish fish is the False scorpionfish (Centrogenys vaigiensis) which is actually a grouper. When they are next to one another, it's easier to tell them apart.
Bengal sergeants (Abudefduf bengalensis), several small Scissortail sergeants (Abudefduf sexfasciatus), many cardinalfishes (Family Apogonidae), damselfishes (Family Pomacentridae) large and small, several Chocolate hind (Cephalopholis boenak), a small Pink-eared emperor (Lethrinus lutjan) and many White-spotted rabbitfishes (Siganus canaliculatus). Also several Seagrass filefishes (Acreichthys tomentosus).
halfbeaks (Family Hemiramphidae).
Fringe-eyed flathead (Cymbacephalus nematophthalmus).
Purple climber crabs (Metopograpsus sp.), I saw one large Red egg crab (Atergatis integerrimus), many Blue-tailed prawns (Family Penaeidae), one large Mud crab (Scylla sp.), and several Ghost crabs (Ocypode cerathophthalmus). There were many small Flower crabs (Portunus pelagicus), and many small Swimming crabs (Family Portunidae) of all kinds. Today, I didn't see any Spotted moon crabs (Ashtoret lunaris).
Saron shrimps (Family Hippolytidae). But they rapidly slunk away into hiding after a few shots.
White spotted hermit crabs (Dardanus megistos).
squids (Family Loliginidae). I'm not sure if these two are the same kind. I also saw one small Ornate leaf slug (Elysia ornata).
Common sea stars (Archaster typicus) widely spaced apart. Only a few were near one another. I didn't see any in 'mating' position.
Favid corals (Family Faviidae). There many large colonies.
Bracket mushroom corals and the small Circular mushroom corals (Family Fungidae) that I saw last month.
Anemone corals (Goniopora sp.), something that looks like a small Encrusting disk coral (Turbinaria sp.) and a few tiny to small colonies of Flowery disk coral (Turbinaria sp.).
Pore corals (Porites sp.) I saw today were rather pale.
Peachia anemone (Peachia sp.) and one Haddon's carpet anemone (Stichodactyla haddoni) in deeper water with an anemone shrimp. I also saw one small mouth cerianthid. There were two large patches of Button zoanthids or colonial anemones (Zoanthus sp.).
Smooth ribbon seagrass (Cymodocea rotundata) seem even larger, with long blades mostly clean of growths. The Haddon's carpet anemones (Stichodactyla haddoni) that have settled among these seagrasses are also still doing well. The patch of Sickle seagrass (Thalassia hemprichii) that has chomped blades again. The Spoon seagrass (Halophila ovalis) which I saw last month for the first time, are still there. The leaf blades are tiny but they seem clean and green.I came across three clumps of Tape seagrass (Enhalus acoroides) with long blades that seemed mostly green and clear of growths.
Mermaid's fan (Padina sp.) and crunchy pom pom seaweed that was growing on ropes and extensively on rockier parts of the shore, together with clumps of green Codium seaweeds (Codium sp.). There were some small but lush clumps of Sargassum seaweed (Sargassum sp.).
Acorn worms (Class Enteropneusta). These long buried worms produce long coils of 'processed sand'. Most of the coil seemed clear of dark stuff.
