Sea mat zoanthids (Palythoa tuberculosa).
Here's what the nudibranch looks like. It's the Cauliflower nudibranch (Dendrodoris tuberculosa) and it was about 12cm long. It has white spots on its underside. Kok Sheng later found an even bigger one!
Glossodoris atromarginata and Phyllidiella pustulosa.
Northern Expedition of the Mega Marine Survey, when Dr Kathe Jensen said they were a new record for Singapore!
Volvotella slugs (Volvatella vigourouxi)? I also noticed that the slugs remained firmly attached to the slugs by a strong strand of mucus, kind of like terrestrial caterpillars.
why they are found in graduated sizes and includes a great video clip of a pair of females fighting. These are False clown anemonefishes (Amphiprion ocellaris) and we missed for a while, until we saw them again on our last trip to Pulau Hantu in Nov 2012. I hope they don't 'disappear' again.
Blue-spotted fantail rays (Taeniura lymma) skulking among the corals. This is why we need to be careful when exploring the reefs. Marcus found a baby frogfish! Fortunately, no one encounter Mr Stonefish today.
Alicia anemone (Alicia sp.)! We have suddenly started seeing these anemones. I'm not sure if it's because we are getting better at spotting them or if it's because they are more abundant on our shores. Something to ask Dr Daphne when she comes for the upcoming Southern Expedition. Meanwhile, we must find the intriguing cousin of the Alicia anemone, the amazing Phyllodiscus sea anemone.
Haeckel's anemone (Actinostephanus haeckeli) almost as soon as we started our survey. Kwan Siong spotted a bunch of posy anemones. While the usual Magnificent anemone (Heteractis magnifica) was still there, I found another one which looks rather different from it, but similar to those I saw on Terumbu Pempang Tengah a few weeks ago.
Coastal horseshoe crab (Tachypleus gigas) and remembered Dr Dennis Gordon's Workshop on Bryozoans and looked for bryozoans on the shell. We found a suspicious cluster.
Nov 2012 trip here. They were of various species. All the Asparagus flowery soft corals (Family Nephtheidae) were still purplish but many had yellowish tips. Most of the bleaching corals were seen at the mouth of the lagoon facing Pulau Bukom, although I saw a few on the reef flats too.
Anchor corals (Family Euphyllidae), Cauliflower corals (Pocillopora sp.). I didn't see any Crinkled sandpaper coral (Psammocora sp.) though.
Horn corals (Hydnophora sp.), Lettuce coral (Pavona sp.) and more. Kok Sheng saw some spectacular corals as he braved the deep reef edge. The water was quite clear today!
leathery soft corals (Family Alcyoniidae) that were bleaching. Various species all looked fine. We were able to better explore the reef flats today because the bloom of Sargassum seaweed (Sargassum sp.) is finally over.
Cushion star (Culcita novaeguineae) on the intertidal at Pulau Hantu. There were also lots and lots of Common sea stars (Archaster typicus) on the sandy shores, many in 'mating' position.
Fluted giant clams (Tridacna squamosa). Kwan Siong spotted one more. Wow, we are so thrilled. But also sad because we couldn't find the Burrowing giant clam (Tridacna crocea) that is usually in the middle of the lagoon. Could the clam have been killed by a boat strike or boat grounding on the lagoon?

mangrove trees that have regenerated naturally on the artificial seawalls of Pulau Hantu. The trees have grown tall and look healthy.
bryozoans on the trees.
NParks volunteer dialogue session with in the afternoon. Now it's time for a short nap before I wake up way too early again tomorrow for another predawn trip to Big Sisters Island.
