It's our first predawn low tide trip this year and on 28 April 2017 we visited Tanah Merah shore. The first exciting find of the trip would be the stonefish!
I later also chanced upon a Knobbly sea star. The corals are still ok though some are dying or dead due to the previous round of coral bleaching. The seagrasses invaded upstream of the canal where we also found tiny white sea urchins and other interesting finds.
