Cardinalfishes are mouth brooders. Usually it is papa fish who keeps eggs in his mouth until they hatch. This fish has a mouth bulging with eggs that seem about to hatch, see the little eyes!
These little fishes are Chequered cardinalfishes (Apogon margaritophorus) which are commonly seen on our shores. There were other carnidalfishes with little orange eggs in their mouths.
Magnificent anemones (Heteractis magnifica) that I've seen!
Fire anemone (Actinodendron sp.) AND a pretty swimming crab that I don't recall seeing recently. Rob says its a Charybdis!
Ridged plate coral (Merulina sp.) was overturned. I was glad I turned it back to the correct position as most of the colony seemed to still be alive.
Favid corals (Family Faviidae), the species most commonly encountered on our reefs. The next most abundant species I saw on this trip was Anemone coral (Goniopora sp.). There were also many Pore corals (Porites sp.) and some Galaxy corals (Galaxea sp.) and Cauliflower corals (Pocillopora sp.). As well as some branching Montipora corals (Montipora sp.) on the higher shore.
Pebble coral (Astreopora sp.), Brain corals (Family Mussidae), Lettuce corals (Pavona sp.) and Carnation coral (Pectinia sp.).
from Terumbu Semakau in June 2010 at the height of coral bleaching. At first I thought this was just another strangely coloured coral. A closer look and I realise it is covered thickly with lots of tiny brown Acoel worms.
Persian carpet flatworm (Pseudobiceros bedfordi) swimming in the water! I don't often see this beautiful animal.
Xenia soft corals (Xenia sp.) found here. I haven't come across these animals on our other reefs yet, aside from those I saw at Terumbu Bayan which has since been reclaimed. I noticed on this trip, that the Xenia colonies actually have a body column, as shown by these droopy ones left hanging at low tide. A very close look at the colony and I realise there are tiny flower-like things at the base of the polyps. Are they a different kind of polyp? Or retracted polyps? Wah, so much more to find out!
Asparagus flowery soft corals (Family Nephtheidae). Most of them seemed healthy although some were rather yellowish. In one of them, I noticed little orange brittlestars! The last time I saw these was when Chay Hoon found some on Cyrene Reef in 2008.
Crown sea stars (Asterina coronata)!
Durian sea cucumbers (Stichopus horrens). I also saw one large fat White-rumped sea cucumber (Actinopyga lecanora).
Razorfish (Family Centriscidae). In deeper waters in the dark, there was constant splashing. Large fishes hunting?
Bartail flathead (Platycephalus indicus) with the typical colourful tail! I don't see this fish too often.
Variable fang-blenny (Petroscrites variabilis) and an Ornate leaf slug (Elysia ornata)!
Glossodoris atromarginata and a very large Discodoris boholiensis. Marcus saw a Discodoris lilacina, my first time having this for Semakau.
octopuses came out to hunt! I also saw one squid (Family Loliginidae) and many many little Pygmy squids (Idiosepius sp.).
Dog-faced water snake (Cerberus rynchops). These snakes are common in mangroves and have bulbous eyes that stick out of the head. Thus allowing them to peek out above the surface of the water while keeping the rest of the body submerged. Alas, we didn't encounter a snake feeding frenzy as we did when we last visited this shore at night in 2009. But Marcus saw a pair of Banded file snakes (Acrocordus granulatus) mating!
cerianthids (Order Ceriantharia) started to emerge in pools on the higher shore.
just been reported that the refineries will "return to full capacity in December" following the shutdown due to the recent fire there.
