Three ladies went to a rocky part of Changi Beach to explore.
This shore we visited used to be very rocky, but it is now rather silty and the substrate can be quite soft.
The shore is covered with shells of bivalves. They are dead bivalves though.
Even though there are many dead bivalves on the shore, I did see some live ones.
|Some type of cockle. Notice how the shell tails off on one side.|
|Cockle - a small and a medium size.|
|Pretty Bean-shaped venus clam.|
There were a number of this fellow buried in the silty ground with the shells opened. It looks like a fan clam but I have never seen the clams in such manner. It looked like there is a inner chamber inside this animal.
I tried to shift it and it closed its shell a bit and reopens them again. So I thought the original position is good enough for me.
Another interesting bivalve I saw was this. It has pretty ridges on the shell surface.
|Pink moon snail|
|Tiger moon snail|
The largest shell animal I saw on this shore would be the Noble volute (Cymbiola nobilis).

Middle: Orange sea cucumber?

I have come to realise that once I see my first sea star, the rest of the sea stars will slowly appear. (Brittle stars not counted though as they are plenty on our shores).
There were the plain sand star (Astropecten sp.), Biscuit sea star (Goniodiscaster scaber) and many brittle stars.

|Upside down brittle star (Ophiothrix sp.)|
|Blue-lined brittle star (Ophiothrix lineocaerulea)|
This disk diameter is around 2 cm long., comparing its size to the seaweed.
|Black sea urchin (Temnopleuris sp.)|
|White sea urchin (Salmacis sp.)|
|Haddon's carpet anemone (Stichodactyla haddoni)|
|Swimming anemone (Boloceroides mcmurrichi)|
|Tiger anemone with visible body column|
|Spiky sea pen|
|Slender sea pen|
Soon the tides came in, which signals the time for me to head back to school to teach.
Yawn, I'm going to be zonked out (and I felt like a half zombie in school).
