Although its common name is Sea Apple, this amazing technicolour creature is not a vegetable or a fruit. It is a sea cucumber. It's eye-poking colour combination is a warning of its toxic nature. Please don't touch or collect this sea cucumber. It does not do well in an aquarium and often, like a toxic bomb, will kill all other animals in the tank. Today, I saw 6 large ones!
Aug 2020, the most abundant were Pink warty sea cucumbers, dotting the seagrass meadows. The next most numerous was Thorny sea cucumbers. I saw many Beige sea cucumbers, many Ball sea cucumbers buried in the sediments and one Garlic bread sea cucumber. I didn't see any Orange sea cucumbers this time. Large White sea urchins dotted the meadows.
Biscuit sea stars are once again common on this shore. I saw many tiny to medium sized ones. I also saw several large Eight-armed sea stars, one of them 'humped up' - not really sure why. I also saw two Spiny sea stars, one small orange Cake sea star near the jetty, one small Knobbly sea star and one Painted sand star.
Green mussels. At the lower level, it was nice to see several small sea fans, many colourful sponges and ascidians and several Pink flowery soft corals. I saw two Milliaris cowries, a Blue feather star, two Black sea urchins, various sea stars and sea cucumbers on or near the legs too. The large Burgundy anemone is still on the jetty legs. I first saw it in Sep 2018. Today, I didn't see any Onyx cowries. The explosion of Tiny red sea cucumbers that I saw on our last survey in Aug 2020 seems to have dwindled, there were only a few large ones on the jetty legs.
Pink flowery soft corals. These often harbour other kinds of animals. Today, I saw an Spindle cowrie snail (which eat the soft coral) and many Tiny colourful brittle stars.
Spoon seagrass (with large leaf blades) as well as many patches of Needle seagrass (with narrow leaf blades). I didn't see any dugong feeding trails. But the meadows were home to many animals.
Window pane clams and Fan shell clams. And these were not over abundant either - I didn't see any clam invasion on this shore.
Haddon's carpet anemones, many of which had tiny carpet anemoneshrimps living in them. I saw several Tiger anemones and Big hermit hitching anemones. I saw only one Flowery sea pen. I didn't see any, but Kok Sheng saw some cerianthids.
Aug 2020. Today, we enjoyed a huge full moon.

What is the future of Changi shores?
Changi shores are precious because they may be reclaimed in the 2013 landuse plan by the Ministry of National Development released in response to 2013 Population White Paper.
