I'm back at Terumbu Raya, a submerged reef off northern part of Pulau Semakau after 3 years! My previous trip was in Jul 2011. Terumbu Raya, also named as The Great Reef in Malay is home to thick growths of hard corals and its associates by the reef edge.
Favid hard coral (Family Faviidae) on the left is partially bleached on the top. We also observed this at Pulau Hantu two days ago. There was also a completely bleached Carnation coral (Pectinia sp.).
Brain corals (Family Mussidae) are more affected by bleaching as compared to other types of hard corals. Ria caught the "cold-bug" by saying it isn't good to be too smart. Can you get the joke? Haha!
Circular mushroom corals (Fungia sp.) and these two are partially bleached.
Tongue mushroom coral (Herpolitha limax) which looks healthy.
Disk coral (Turbinaria sp.) and Ridged plate coral (Merulina sp.).
Pebble coral (Astreopora sp.), brown Carnation coral (Pectinia sp.) and the blue Favid hard coral (Family Faviidae).
Euphyllid coral (Family Euphyllidae)? What do you think it is? :)
Four-spot cowrie (Cypraea quadrimaculata). It is only my second time seeing it.
Moon coral (Diploastrea heliopora) is a Bulb-tentacled sea anemone (Entacmaea quadricolor).
Tomato anemonefish (Amphiprion frenatus).
Magnificent anemones (Heteractis magnifica) on this reef. I only saw two today.
Fire's anemones (Actinodendron sp.) are more common on Terumbu Raya! In fact, Terumbu Raya is one of the few shores where I first learnt about this nasty-stinging anemone.
Starry mouthed nudibranch (Bornella stellifer) was also last sighted at Hantu two days ago.
Lined chromodoris nudibranch (Chromodoris lineolata), Black-margined nudibranch (Glossodoris atromarginata), Black phyllid nudibranch (Phyllidiella nigra) and Pimply phyllid nudibranch (Phyllidiella pustulosa) (from top left to bottom right).
Dragonfish sea cucumber (Stichopus horrens) on Terumbu Raya though it has been sighted here before.
Cushion stars (Culcita novaeguinea)! These huge and heavy sea stars are usually found on healthy reefs and they are capable of feeding on hard corals.
Fan-bellied filefish (Monacanthus chinensis). It was rather motionless even when I drew nearer to the fish.
Tiger cowrie (Cypraea tigris)! Though I have seen it in a few occurrences, this is the first time I spotted it by myself. Hahaha.
ccording to the Singapore Red Data book, although this cowrie was considered one of the commonest cowries of the Indo-Pacific, and present on Singapore reefs in the past, the tiger cowrie is now exceedingly rare.
Fluted giant clam (Tridacna squamosa) by the reed edge! Not sure if this fellow was previously sighted by the others.
