It is not the sound of love when many mosquitos were buzzing close to my ears throughout the intertidal survey trip at Chek Jawa. This trip has got to be the earliest intertidal survey trip I had ever embarked on. The mosquitos were not the only organisms expressing their "love" to me. My nose was also expressing its "love" to me as I sniff, sniff, sniff and even more sniffing throughout the whole time I was on the shore.
My nose and the mosquitos may be hindering my attention span on the shore, but my vision did not fail me. On my very first intertidal survey trip on Chek Jawa, there are many interesting critters to be seen.
Reaching the shore at about 2am, the tide was still quite high for the coral rubble area to be exposed. We began our survey by checking the pillars that supports the boardwalk along the coast. It was full of life.
There were plenty of these tube structures weaved on the pillar surfaces, which I think are worm tubes.

This is not scum but it is actually a sap sucking slug found by Chay Hoon, our sea slug enthusiast. Chay Hoon shares on her Facebook that this sap sucking slug has been identified by Dr Kathe Jensen to be from the genus Pattyclaya. Dr Jensen is not sure of the exact species at the moment but it could be a new species.

It is a tiring effort to document our precious shores, but I enjoy do it and I have learnt a lot about our biodiversity. Only very few of us are crazy and dedicated enough to wake up at such crazy timings (like 1am) in the morning to survey the shores and share with everyone the marine biodiversity Singapore has.
This intertidal survey trip was possible with permission and support from the National Parks Board (NParks).
