Spider conch spotted by Meilin.
Ria showed us this immense Chiton. Apparently some species can grow even larger, up to a foot long but this one is very big for a shore sighting in Singapore.
Bian spotted this vivid green shrimp. It seemed to be carrying eggs.
More shrimps. One of them appears to be white instead of transparent.
The land hermits emerged after dark.
Sally lightfoot (Grapsus albolineatus). This one seemed to have lost a couple of limbs.
Tiny spider crabs lurk among the seaweed.
Isopods.
Marine spider. Its feet were hardly making any depressions on the floating scum.
A tiny brittle star makes its way across the seaweed.
Mysterious encrustation.
Tiny blue zoanthids spotted by Meilin.
Fish (Diamond tuskfish Halichoeres dussumieri/nigrescens?) lurk among the seaweed.
Pygmy squid show themselves once again.
Octopuses are masters of disguise.
And there were many of them at St John's today.
Including some tiny ones.
Blue dragon, always pretty.
Armina nudibranch (Dermatobranchus sp.) spotted by Bian. This one seemed to have an egg collar at its rear end, no idea if it just laid them or the eggs belong to something else.
Brown striped flatworm (Pseudobiceros gratus).
Maritigrella virgulata. It went unnoticed in the very same pool of water as the Brown striped flatworm which was taking up all our attention until Meilin spotted it when she arrived not knowing what we were looking at.
Pseudobiceros uniarborensis.
The tiniest Acanthozoon I've seen yet, 1.5cm long.

Wow, that's a huge chiton!
The third isopod is actually an amphipod. Amphipods are flattened sideways, while isopods are flattened top to bottom.
