Hey, thanks for this post- I went at low tide (by luck) some time ago and wondered what it would look like at high tide.
Here are some snaps from my sister-in-laws point-n-shoot camera and a couple from my G1 (not great but nice to compare with the high tide shots).
At catfish (really small; about 6cm long)
Chek Jawa tidal plain with a nice storm over S'pore in the background
A broiled (quite dead) Horseshoe crab
Another view of the tidal plain (poor quality scan)- that's me on the right!
A starfish- sorry no polariser
