Changi Creek in Jan-Jun 2015?
The narrow shore along the beach has changed in shape. There are large sand bars bare of seagrass and the entire area is much firmer. In the past, it was much softer.
July 2015 and also noticed changes on the shore and declines in marine biodiversity.
Big-headed seagrass octopuses here. Today, I saw one. These poor animals are often harvested by fishermen and used as bait.
Spiral babylonia snails. This beautiful snail was identified as a new record for Singapore in 2013. Before then, we have not seen them. Now, we often see them on Changi, as well as East Coast and signs of them at Pasir Ris. Where did the snails come from? Does this suggest a change in our shores?
Ball sea cucumbers on the sand bars.
Smooth sea cucumber. Here's a view of a Ball sea cucumber and Smooth sea cucumber before and after they were gently dug out. After taking the photo, I put them back exactly the way they were.
Pink warty sea cucumbers, and only a few Thorny sea cucumbers. I also saw one small Garlic sea cucumber. The rest of the team saw a Sea apple sea cucumber which I missed. We usually see other kinds of sea cucumbers here.
Pencil sea pens, one Flowery sea pen and two Slender sea pens. I saw a few Cerianthids. I didn't see any sea fans.
Painted sand star and one small Biscuit sea star. In May 2015, we saw many Biscuit sea stars here.
Luidia sand stars which are often seen in this location.
hitching on shells occupied by hermit crabs. I also saw several Striped sand anemones, and one Peachia anemone.
Tiger anemones in a small area where the ground was still soft. I came across one Mini carpet anemone, but I didn't come across any large Haddon's carpet anemones. I also saw one tiny Seagrass anemone.
Spoon seagrasses with large and small leaf blades.
Mermaid fan seaweed growing on one of the large boulders. But zero sponges were growing on the rocks. I am getting more and more disturbed by the recent decline in sponges along the length of Changi and at Pulau Ubin, Chek Jawa and Pulau Sekudu.
Crown sea stars, and sprinkles of Banded bead anemones.
