This is an overdue post of our survey at the natural reefs of Semakau during the last low tide season. In fact, the team covered three different areas of Pulau Semakau though I only went for the eastern and northern shore (missing out the southern shore).
When I first took this photo, I thought that the water was murky as the photo was slightly blurry. Subsequently, I also noticed this in other underwater shots and did not think much because when sediments are stirred, visibility drops.
Magnificent sea anemones (Heteractis magnifica).
Bubble tip sea anemones (Entacmea quadricolor) and some of them are home to the Tomato anemonefish (Amphiprion frenatus).
Burrowing Giant Clams (Tridacna crocea)! This fellow is sometimes also called as the Boring Giant Clam as it can bore into rocks. No worries ok because it doesn't bore its friends!
Cushion stars (Culcita novaeguinea) that can come in various colours and patterns.
Wiggly reef star anemone. It is very shy and disappears instantly at the slightest sign of danger. I like this shot as it is found among the colourful zoanthids.
Chitons (Class Polyplacophora) underneath a rock. These creatures do cling on tenaciously. Don't even try to pry them off.
Varicose phyllid nudibranch (Phyllidia varicosa). It is bigger than the other usual phyllid nudibranchs that we see.
Black-margined nudibranch (Doriprismatica atromarginata). I wonder if they are mating?!
Pizza anemone (Cryptodendrum adhaesivum). I wonder if the yellow colouration is due to bleaching.
Red feather stars (Himerometra robustipinna) are found abundantly on certain reefs, I only saw one at the edge on this trip. The ends of the arms seem to have fallen off before.
Herrmann's sea cucumber (Stichopus herrmanni).
Fluted giant clam (Tridacna squamosa)! Mei Lin's infectious love for these pretty clams have also caused us to be thrilled when we come across them.
