The long awaited June Holidays is here where I will be able to do our morning intertidal surveys for 6 days back to back! The first trip is always the hardest as we have to wake up the earliest (at 2am) for our survey at Pulau Sekudu.
Fluffy hydroids. And I was surprised to see the hydroids move! This is because it came together with a crab decorated with the hydroids! Can you spot the crab in this photo?
Black-margined nudibranch (Glossodoris atromarginata) which is usually found more commonly in the southern waters of Singapore.
Tiny black Gymnodoris nudibranchs (Gymnodoris sp.).
Gymnodoris nudibranch (Gymnodoris sp.) that we have also seen at Sekudu before in 2010.
Cyrene in 2011.
Stone crab (Myomenippe hardwicki) which found in the mouth of the Haddon's carpet anemone (Stichodactyla haddoni).
White sea urchins (Salmacis sp.), Stone crabs, and an explosion of baby
Plain sand stars (Astropecten indicus) and Painted sand stars (Astropecten sp.).
Knobbly sea stars (Protoreaster nodosus).
Common sea stars (Archaster typicus) and did not find as many of them as like the previous trip. Nevertheless, good to know that they are still around.
Crown sea stars (Asterina coronata). They are sometimes also known as the Rock sea stars.
Long spined black sea urchins (Diadema sp.) are usually found and they are still there! The fishies are swimming around the sea urchin. I think it's some sort of protection for them though I'm not sure how they can avoid being hurt by the spines of the urchin. Haha!
White sea urchins (Salmacis sp.) and many of them do "carry" shells and other bits and pieces with them as a form of camouflage.
Pink sand dollar (Peronella lesueuri) that has been regularly seen on Sekudu. This particular sand dollar looks like it has been chomped before by a predator. So far, we have only seen this sand dollar at Sekudu and Changi.
Pink flowery soft corals (Dendronephthya sp.) can be found nearer to the coral rubble and they are home to commensals.
Tiny colourful brittle stars (Ophiothela danae).
Graceful cowrie (Purpuradusta gracilis).
Blue-spotted fantail ray (Taeniura lymma).
Thank you Nparks for giving us permission to document Pulau Sekudu. As part of the Chek Jawa Wetlands, this island is out of bounds to the public.
