Here's another look at the Haekel's anemone (Actinostephanus haekeli). Those I've seen in the past were all black. My first time seeing one expanded that had brownish tentacles.
Sargassum seaweed (Sargassum sp.), normal for this time of the year. It makes it tricky to walk through as we don't want to kill marine life or step on Mr Stonefish! On the plus side, it didn't rain!
The reef lies near Pulau Bukom, on the horizon. And yet, it has lots of marine life!
Favid corals (Family Faviidae). With a few Pore corals (Porites sp.). Most of them were not bleached.
badly affected the corals here in 2010.
Acropora corals (Acropora sp.).
Tape seagrass (Enhalus acoroides) were all short and cropped. I saw several small patches like this. There were a few patches with sparse but long blades, mostly in the Sargassum zone.
Serrated ribbon seagrass (Cymodocea serrulata). I saw several patches of Spoon seagrass (Halophila ovalis). I didn't come across any Noodle seagrass (Syringodium isoetifolium) which we have seen here in the past.
March 2011. At that time, most of the Tape seagrass (Enhalus acoroides) were short and 'chopped'. But all the previously recorded species were seen: including the rare Noodle seagrass (Syringodium isoetifolium), Serrated ribbon seagrass (Cymodocea serrulata) and lots of Spoon seagrass (Halophila ovalis). .
And the lush growths seen on our first visit to Terumbu Semakau in May 2010. TeamSeagrass monitors seagrass health on nearby Pulau Semakau and similar habitats like Cyrene Reef. Hopefully, this data will help us better understand what is happening to seagrasses on all our shores.
Even in the high murky water, I could still see interesting marine life. Here's a little Spotted top shell snail (Trochus maculatus). It was clinging fiercely to the rock. Perhaps laying eggs?
Hammer oyster (Malleus sp.). Interesting internal structure!
Noble volutes (Cymbiola nobilis). I saw two of them (about 8cm long).
Prickly yellow sponge (Pseudoceratina purpurea) and realised it too may have clams embedded in the branches. Some of the bumps were flattish with a slit around the edges. When I touched them, the slits closed up!
Jorunna funebris. Even Chay Hoon couldn't find any special nudis. The tide was just too high. But Russel spotted some squids! And James got good shots of a flatworm possibly eating an ascidian.
leathery soft corals (Family Alcyoniidae), flowery soft corals (Family Nephtheidae), Frilly sea anemones (Phymanthus sp.), two Giant sea anemones (Stichodactyla gigantea). I saw several Hairy crabs (Family Pilumnidae), a Red egg crab (Atergatis integerrimus), many swimming crabs (Family Portunidae). Also one fan worm (Family Sabellidae).
zoanthids (Order Zoanthidae) and ascidians give a touch of colour on coral rubble.
June 2011, we did come across a very long driftnet laid across the reef. Driftnets not only kill fish but also rip up corals and other immobile marine life. Fortunately, on this trip, we didn't see any nets. There was one old broken fish trap which we flattened.
