With permissions from National Parks Board, we are back at Pulau Sekudu to do our annual survey. Otherwise, this island is actually out of bounds.
Knobbly sea stars (Protoreaster nodosus)!
Pore hard corals (Porites sp.) is partially bleached.
Flowery soft corals (Family Nephtheidae) are bleaching. Nonetheless, this made commensals more prominent. I managed to spot this Soft coral false cowrie (Family Ovulidae).
Ball flowery soft corals (Family Nephtheidae) seem unaffected.
Posy anemones. Most of them seem to be doing ok.
Sea fans or Gorgonians (Order Gorgonacea) are doing alright but they seem to be not as abundant this year.
Purple branching sponges (Callyspongia sp.). The sponge situation is also better!
Black prickly nudibranch (Atagema intecta). It was actually laying eggs.
Lined chromodoris nudibranch (Chromodoris lineolata), Fine-lined flatworms, Blue-lined flatworm (Pseudoceros sp.) and also the Purple-spotted yellow flatworm (Pseudoceros laingensis).
Mosaic reef crab (Lophozozymus pictor) is the most poisonous crab of Singapore! There were several documented deaths caused by eating this crab. We seldom see them on northern shores as they tend to be sighted in the southern reefs.
Thick-edged sand dollars (Jacksonaster depressum).
Hollow-cheeked stonefish (Synanceia horrida) inside the bubu fish trap that was later disabled. The stonefish is one of the most dangerous fishes on our shores. It has tough dorsal fin spines that can penetrate thick soled shoes.
They are called stonefish simply because they look like a stone and remain rather motionless most of the time, just like a real stone.
Haddon's carpet anemones (Stichodactyla haddoni).
