I started out the fieldtrip slightly different today. Instead of heading straight to the lagoon, I went to check out the crinoids with Kok Sheng first. We saw many pretty crinoids of various size and colours.

Oh what is this suspicious cone-shape snail moving very slowly on the rock?

Chay Hoon also found a Chromodoris fidelis nudibranch. This is my first time seeing this nudibranch on our shores and also my first time seeing it on intertidal. However I have seen it in Indonesia when diving.
Here's a video I recorded of the nudibranch (video recorded in supermacro mode on Olympus TG-1).
There were a total of three different flatworms seen on this trip, each of them with video. One of the flatworms seen seems to be new to the intertidal record.
|Blue-lined flatworm (Pseudoceros sp.)|
|Dawn flatworms (Pseudobiceros uniarborensis)|
|New flatworm sighting. Identity is unknown at the moment.|
It was a great fieldtrip with very mild drizzle towards the end of the trip.
