It's my last chance to have a look at Changi's rocky shores for the morning low tides. I'm also wondering how the strange 'armoured' sea cucumbers here are doing.
Stinging hydroids. As usual, there were lots of these skeleton shrimps hanging on to these.
And here's a closer look at the very tiny tentacles on the individual animals of this colony. I can't believe such tiny animals can pack the painful zap we get when we merely brush against them. I noticed a coil of eggs laid on one of the 'fronds'. I guess it's a safe place to lay eggs!
June, I sense some changes. I didn't see any living sea fans (Order Gorgonacea) aside from this single one. Oh dear.
feather stars (Order Crinodea), here's one of them. Next to it is a fanworm (Family Sabellidae) which may look similar at first glance.
Blue spotted flatworm (cf Pseudoceros indicus) is seen suspiciously near Yellow clustered ascidians (Eudistoma sp.). I strongly suspect that these flatworms eat the ascidians.
'armoured' sea cucumbers that I first saw in June. The top photo I realise is of three of them! I notice they are sometimes 'buried' under gunk with only a tiny blob of either their butt or mouth sticking out.
purple one and one orange one. There were many Crown sea stars (Asterina coronata) everywhere.
sponges both on the rocky shore and encrusting other hard man-made surfaces. There were also still many clusters of Zebra corals (Oulastrea crispata).
nest mussels (Musculista senhousia). Nearer the low water line were many clumps of zoanthids (Order Zoanthidea).
flowery sea pens (Family Veretillidae) and cerianthids (Order Ceriantharia).
Hairy spoon seagrass (Halophila decipiens). I've been seeing this on many parts of Changi growing on Nest mussel carpets in particular.
in June. Did the small patch grow this fast in such a short time? Wow.
After a quick look at this shore, I hopped over to another part of Changi where I tried to figure out why there is less seagrasses there.
Today, I didn't do the intertidal survey as there were so many things to do in such a short tide.
