Seastars, Sea Cucumber, Seahorse and interesting Flatworm at less hazy Changi

A team head out for Changi shore this morning with haze condition of about 89 on a 3hr PSI.

What is so special about this part of Changi shore would be the hard-to-spot-at-first Armoured sea cucumber.

The Armoured sea cucumber is easily overlooked as ascidian or hard coral. Covered with silt, it blends in very well on the silt covered surface and looked just like any other blobs. Only when the first Armoured sea cucumber is spotted, the rest appear magically.

Nemo, Fantail Rays and Giant Clam at Terumbu Bemban, CMBS

It's the second day of reef survey for the Comprehensive Marine Biodiversity Survey (CMBS) Southern Expedition. At 3am, bigger group of staff, scientists and volunteers gathered at the dinning area for breakfast. There are 3 teams heading out for reef survey this morning, all to different locations - Big Sisters' Island, Terumbu Bemban and Beting Bemban Besar.

It was important to sort the teams right before boarding the 2 boats by Summit Marine System. Terumbu Bemban and Beting Bemban Besar may just be next to each other, but efficiency in transporting the correct people to the correct location is crucial as we have limited time on the exposed submerged reef due to the low tide window.

First Predawn Reef Survey for CMBS at Terumbu Semakau

It has been 6 days since the Southern Expedition for the Comprehensive Marine Biodiversity Survey (CMBS) started. Yesterday was my first time stepping into the base camp for the expedition, meeting familiar and new faces. I am involved in CMBS as a volunteer since Dec 2010 as a regular volunteer. The Southern Expedition is the second expedition event I had participated in, with the first at the Northern Expedition held in October last year.

Another great day out in the field today as we explore Big Sisters' Island.
As soon as we started, Ria found a pair of Tiger-tail seahorse (Hippocampus comes).

However I only see one giant clam with the help of Marcus.
