A small team returns to survey a sandy stretch of East Coast Park that has been taken over by seagrasses!
There were lots and lots of small to medium sized Cake sand dollars!
Grey bonnet snail. Here's a half buried snail that appears to be sneaking up to a sand dollar.
Fig snail also eats sand dollars and other sand-dwelling creatures. Bonnet snails and fig snails are rather rare in Singapore because we have lost our flat sandy shores to reclamation. It's nice to see these animals returning to our artificial shores.
Button snails. On my trip here in Jan 2013 and Aug 2012, these snails were so abundant on large stretches of the sand bar that they were revealed in my footsteps on the sand! But today, there were not as many.
Ball moon snail moving about above ground (they are usually buried in the sand) and a small Lined moon snail. There were also many sand collars, which are the egg mass of moon snails.
Weasel olive snails on the sand bar. I didn't see any other kinds of Olive snails.
Plain sand star (which is believed to eat Button snails) and one White sea urchin.
Striped bead anemones. Also many Peachia anemones. Buried in the sand, I saw one Smooth sea cucumber, and several Acorn worms. As well as one Peanut worm.
Spotted mooon crabs. This one was in a pair. I often see this kind of pair of big crab holding onto a small crab. Are they getting ready to mate? Is the small one the male?
Jun 2015, so I didn't get to see the seagrasses in deeper waters. But there was lush growths of broad Needle seagrass and Spoon seagrass with large leaf blades even at the mid water mark. There were some Crunchy pom-pom red seaweeds too. I only recorded seeing a tiny patch of Needle seagrass here in Aug 2012.
Swimming crabs of various kinds. I also saw one small Stone crab. I also saw a few small Orange-striped hermit crabs.
Mud crab. It was quite lively. Washed up on the tideline, I saw many large pincers that look like they belonged to Mud crabs. Were these crabs released on the shore?
Haddon's carpet anemone chomped on? Or has it tucked most of it oral disk into its body column? There was one anemone shrimp clinging on to the anemone. I didn't come across any of the usual colourful sea cucumbers that we see in seagrass meadows.
