Besides Chek Jawa, there are other Ubin shores that are just as beautiful. A small team explored one such shore this morning well before dawn.
Chek Jawa and Pulau Sekudu, as well as Changi opposite.
Kok Sheng first brought us here in Dec 2009, and we returned in May 2010, Dec 2010 and Dec 2012. During those surveys, the rocks were coated in colourful sponges, ascidians, soft corals and sea fans. This morning, they were quite bare. But we did see some interesting marine life.
There were some small sea fans growing on the rocks in deeper water. I saw Candelabra sea fans amd Gnarled sea fans.
Asparagus sea fan which I usually only see at Beting Bronok. Fouling organisms appear to be starting to grow on it.
Zebra coral on the rocks in deeper water. As well as tiny clumps or scattered polyps of Cave corals. I saw only a few clumps of Candy hydroids and zoanthids. There were also some clumps of Ball-tip corallimorphs.
Blue feather stars and one Black-and-white feather star.
Biscuit stars and one medium Cake star. But no other kinds of sea stars. I only saw one thorny sea cucumber.
Prickly ball sponge, a small patch of Elegant branching sponge, some clumps of Rainbow sponge. There were many patches of Melted chocolate sponge. Chay Hoon of course managed to spot some interesting nudibranchs.
Thumbs up ascidians and Yellow clustered ascidians. The patch of ascidians below seems to be getting coated with a green scum.
Blue spotted flatworms. Flatworms eat immobile animals such as ascidians. This one is well wrapped around a Yellow clustered ascidian and is probably eating it.
Onyx cowries as well as the more commonly seen Ovum cowries. Still abundant on the rocky shores are Banded bead anemones and onch slugs. As well as many Drills laying yellow egg capsules. There were also many Haddon's carpet anemones.
Armoured sea cucumber. The first one I've seen outside of Changi.
Noble volute which was clutching something in its foot.
Spoon seagrasses on the softer parts of the shore as well as a lot of pink fluffy stuff which might be some kind of seaweed or cyanobacteria. The stick-like thing is a Slender sea pen!
Spiky sea pen. It had a tiny porcelain crab in it that looks different from the ones I usually see in this sea pen.
die a slow death. Please do not release balloons!
