A dawn survey at Cyrene and I saw Burrowing giant clams here for the first time!
Although it lies in the middle of an industrial triangle and major shipping lanes, Cyrene has some of Singapore's best shores. The rest of the team saw lots of Knobbly sea stars and other wonderful marine life.
I was excited to see not one but two Burrowing giant clams! This is our first sighting of this for Cyrene.
The reefy part of Cyrene appears to be doing well. Similar to what I saw on our last survey in Apr 2018, I saw many large hard corals. None of them were bleaching.
Many of the small corals were whole, without bald patches. They were mostly Pore corals and Merulinid corals of various kinds. There were a few Disk corals, some Anemone corals, and some Cauliflower corals. All of them looked well.
I even saw a Red coral crab in one of the Cauliflower corals.
I also saw many large Leathery soft corals of various kinds. None of them were bleaching.
I saw many Flowery soft corals and they were all not bleaching. There were also some sponges, including one small Barrel sponge that looked alright. I was relieved to see this since we saw dying Barrel sponges at Sentosa Serapong in June 2018.
Today, I was trying to help Nicholas Yap to find special anemones. We came across various sea anemones including the 'Hat anemone', a Common peachia anemone, Frilly anemones, Giant carpet anemones, while the rest of the team found Snaky sea anemones.
I didn't really get to explore much of the seagrass situation. But the areas I covered seemed lush, although Tape seagrasses are still cropped.
There were lots of Olive flatworms today. Nicholas spotted a Very long ribbon worm. And there were other worms like the White spiral fan worm.
Cyrene has living sand bars with all kinds of marine creatures.
Today, we came across several Ramose murex snails. In the sand, there were many special snails such as the Eggwhite moon snail, China moon snail, and various Olive snails.
The only nudibranch I saw was this Jorunna funebris which looked like it just laid the egg ribbon nearby. I also saw one Spotted sea hare.
There were lots of Common sea stars. And Cyrene is one of the few shores where I see smaller males, on top of larger females.
I didn't go to the part of the shore where all the Knobbly sea stars were gathered. But Abel and the rest of the team did and it seems they are still alright.
As the tide rushed in, I noticed the Huddling hermit crabs were clustered near the waterline. Probably getting ready to hide in the sand from incoming predators?
On the steep slope of the sand bar, I also saw a living Pink-speckled shrimp-goby sticking out of a hole face out, and a living shrimp in a hole butt up. Not really sure what is happening.
The tide was really rushing in! Here's the first group on the big boat taking shots of the second group with barely any shore still sticking out of the water.
We arrived before sunrise, with a huge plume of emissions hanging over Pulau Bukom. On Jurong Island, I notice large piles of sand near the waters' edge that I first saw in Apr 2018.
Despite these pressures, the shores of Cyrene remain alive.
