I spent a glorious morning at Changi searching for bryozoans and hydroids for the workshop later that day. I zipped by two different shores during this one low tide, to try to get a good variety of these animals for the workshop.
There are lots of colourful sea cucumbers on this shore including the awesome multi-coloured Sea apple sea cucumber (Pseudocolochirus violaceus), a strange orangey pimply sea cucumber and many Warty pink sea cucumbers (Cercodemas anceps) as well as Thorny sea cucumbers (Colochirus quadrangularis).
'armoured' sea cucumbers is still found here. This one was huge (for this kind of sea cucumber), more than 1cm long!
Cerianthids (Order Ceriantharia) aka peacock anemones, as well as true sea anemones like Haddon's carpet anemones (Stichodactyla haddoni).
sea fans (Order Gorgonacea) on a part of Changi that I usually skip over. Sadly, many of the sea fans had been uprooted by fishing lines.
Red spindle cowries and Tiny colourful brittle stars (Ophiothela danae).
Cake sea star (Anthenea aspera), large Biscuit stars (Goniodiscaster scaber), two Eight-armed sand stars (Luidia maculata) but which had only six arms. As well as several Crown sea stars (Asterina coronata).
Ball flowery soft coral (Family Nephtheidae) and one large Pink flowery soft coral (Dendronephthya sp.).
sponges in all kinds of shapes on the rocks.
feather stars (Order Crinodea) and some pretty brittle stars.
glassy branching bryozoans and almost
gave up. But just as I was heading home, I decided to check this tyre
hanging from a tree. Hurray, in the water collecting in the tyre, there
were small clumps of these bryozoans! As well as clumps of tiny
Nest mussels (Musculista senhousia) and embedded in them I saw what looked like the Hairy spoon seagrass (Halophila decipiens). There were few clumps of zoanthids (Order Zoanthidea). I saw one Miliaris cowrie (Cypraea miliaris).
I didn't see any seahorses, octopuses or other spectacular creatures. I hope it's just because I dashed through these locations rapidly and just overlooked them. The last time I visited these shores was in Jul 2012 and Aug 2012.
I was very excited to find out more about the bryozoans and hydroids of Changi, as well as those the rest of the workshop found on their trip to Sisters Island this morning.
