The pretty Pink hypselodoris nudibranch! We almost always see this nudibranch on this stretch of rocky shore at Changi!
I was intrigued by the odd 'branch' curled around some abandoned and encrusted fishing nets. It turned out to be the tail of an Estuarine seahorse (Hippocampus kuda) that was hanging upside down out of water! It must have gotten caught in the low tide. We put it into some water in a rock pool and it seemed fine. I haven't seen a seahorse here since 2011.
zoanthids (Order Zoanthidea) on the shore and noticed all kinds of animals living among the zoanthid polyps: A kind of fanworm (blue arrow), a sea cucumber (yellow arrow) and possibly a sea anemone (orange arrow).
Blue spotted flatworm (cf Pseudoceros indicus), suspiciously wrapped around ascidians, eating them? The rest of the team saw a strange flatworm that we have not seen before.
sea fans (Order Gorgonacea) on this shore too, but not as many as I had seen in Jun 2012. I saw some sea fans that had recently died. I saw some cerianthids (Order Ceriantharia) but didn't see any flowery sea pens (Family Veretillidae) or Slender sea pens (Virgularia sp.) and didn't see any pink flowery soft coral (Family Nephtheidae).
Stinging hydroids. In this clump, a mama squid had laid her egg capsules! Perfect protection for her young ones.
Zebra corals (Oulastrea crispata) and smaller patches of other kinds of corals. There were also lots of fan worms (Family Sabellidae) among the rocks.
'armoured' sea cucumber that I first saw in Jun 2012. I was glad to be able to show them to the team so they can help look out for more. They seemed larger and I saw them even out in the open. There were also many other kinds of sea cucumbers here like the purple and orange ones, and even one large Garlic bread sea cucumber (Holothuria scabra).
brittle stars (Class Ophiuroidea). These fast-moving animals rapidly hide even from torchlight and are seldom seen during the day.
feather star (Order Crinodea), but Kok Sheng found five and they had all kinds of interesting animals living on them.
Ludia sand star (Luidia sp.) that seemed to have lost some of its arms. Among the identifying features of sea stars at the structure of the tiny features on their bodies.
Eight-armed sand stars (Luidia maculata) with only six arms. We seem to be seeing this 6-armed sea star regularly. Perhaps it is some other kind of Luidia species?
Plain sand star (Astropecten sp.), a Spiny sea star (Gymnanthenea laevis) and many Crown sea stars (Asterina coronata), most were dull and rock-coloured but we found one that was bright orange.
swimming crabs (Family Portunidae) in the water. The rocks were full of Purple climber crabs (Metopograpsus sp.) and in the water there were many large Stone crabs (Myomenippe hardwicki). On the pillars Mangrove tree-dwelling crabs (Selatium brocki). There were also many Ovum coweries (Cypraea ovum) on the rocky shore.
halfbeaks (Family Hemiramphidae) on the water surface, to many little cardinalfishes (Family Apogonidae), gobies (Family Gobiidae), several False scorpionfishes (Centrogenys vaigiensis). I also saw one Carpet eel-blenny (Congrogadus subducens), a small toadfish (Family Batrachoididae) and several damselfishes (Family Pomacentridae).
Synaptid sea cucumbers (Family Synaptidae) that are often seen on sponges.
sponge crab (Family Dromiidae) holds onto the sponge and carries it around as protection.
Spoon seagrass (Halophila ovalis) that look like they have been burnt. I couldn't see the lush patches of Spoon seagrasses at the stream mouth that I saw in 2011. I didn't see any of the Hairy spoon seagrass (Halophila decipiens) that I saw on my trip in Aug 2012 and Jun 2012.
