Cerberilla nudibranch (Cerberilla sp.). I also found a new sea anemone and other curious creatures.
My sea anemone surprise was this tiny little sea anemone. In the past, I usually dismiss it as a young Peachia anemone (Peachia sp.). Today I took a closer look, I realised it had a 'hard' body column encrusted with sand, somewhat like the Wiggly star anemone. Another Edwardsid?
Seagrass sea anemone again. I last saw these at Cyrene Reef.
Ball sea cucumber (Phyllophorus sp.). The smooth one on the right is a sea anemone!
seagrass octopuses look quite different from the kind we usually seen on our reefs.
Ball sea cucumber (Phyllophorus sp.), but after taking a closer look, I'm not too sure.
Spoon seagrass (Halophila ovalis) on the shore. Here's a slide show of the transects I did today.
Nest mussels (Musculista senhousia)!
Ball sea cucumbers (Phyllophorus sp.) and Black sea urchins.
Orange sea cucumber and one Purple sea cucumber.
Plain sand stars (Astropecten sp.), but I only saw one tiny Biscuit sea star (Goniodiscaster scaber).
Seagrass pipefishes (the one in the photo seems to have a fish leech on its head, eeks). Also a tiny green filefish (Family Monacanthidae) and lots of little gobies (Family Gobiidae).
Spaghetti worm which disappeared completely into the silt when I looked under the Sea lettuce.
snapping shrimps (Family Alpheidae) of all kinds, tiny and not so tiny shrimps and porcelain crabs too.
carpet anemone (Stichodactyla haddoni). Also some cerianthids (Order Ceriantharia), which are sometimes called Peacock anemones although they are not true sea anemones.
Calf moon snail (Natica vitellus), a Tiger moon snail (Natica tigrina) and also good to see many large Olive whelks (Nassarius olivaceus). The one in the photo had a barnacle growing on its shell. Half buried in the mud were also many Gong-gong snails (Strombus turturella).
gobies (Family Gobiidae) and snapping shrimps (Family Alpheidae).
Spearer mantis shrimp (Harpiosquilla sp.)! I haven't seen one for a long while. It wriggled away rapidly into the Sea lettuce.
Stone crabs (Myomenippe hardwicki) especially near the scattered rocks on the shore, which were encrusted here and there with Rainbow sponge (Suberites sp.) and dotted with small colonies of Zebra coral (Oulastrea crispata).
worst littering situation on our shores, and earlier in the year incidents of mass fish deaths. I wish I could check up on this shore more often. My last visit to the Pasir Ris intertidal was nearly a year ago! There are just not enough low tides to do all our shores as often as I would like to.
The last series of super low morning tides for the year kicks off this week. Last chance to see our favourite shores at their best.
