A small team surveyed Cyrene in the dark, when animals are more active. It's been a while since we did this.
The seagrass cover in this Eastern part of Cyrene has grown very thin compared to the past. Despite this, I saw many furrows that look like they were made by feeding dugongs. These trails are formed when dugongs chomp up seagrasses including their roots, leaving a shallow meandering furrow of about equal width and depth. I've seen these furrows here on past surveys too. This is a view of a feeding trail with petrochemical plants on Pulau Bukom on the horizon.
Kok Sheng saw one more too!
Dayna saw a cone snail! The cone snail is one of the most dangerous animals on Singapore shores. The snail can inject bare hands and bare feet of swimmers and shore explorers in shallow water.
And Jianlin saw another Cone snail! Its tiny 'harpoon' is hardly felt so victims are often unaware until they show symptoms. The toxin can have serious effects and death in humans. No antivenin is available for cone shell envenomation.
We saw a pair of large nudibranchs (Platydoris scabra) that appeared to be mating. I saw one Giant carpet anemone (no anemonefishes), many Frilly anemones, one Dawn flatworm. I only saw one Knobbly sea star, but the rest of the team saw more as well as other interesting fishes and nudibranchs.
And even sharks as they rush in with the tide to feed. In fact, Dayna took a photo of a black tipped reef shark in the shallow waters!
It was a short tide window and I didn't get a chance to check out the centre of the shore, here seen with the lights (and emissions) of Jurong Island on the horizon.
an industrial triangle and major shipping lanes, Cyrene has some of Singapore's most amazing shores.
Let's hope it stays safe until we can visit again.
