Nearly a decade since my last trip here, I returned to this vast sandy shore, a habitat that is now rare in Singapore (thus 'lost') and home to animals that we seldom see on our other shores.
The most abundant animal on this shore were Cake sand dollars! They covered some areas so thickly we just didn't walk there.
Keyhole sand dollars, with slots in the body. But these are a more rarely seen kind, possibly Echinodiscus auritus.
Button snails, but they were not as lively as those seen elsewhere - didn't burrow away quickly when they are revealed. I'm not sure why. Also abundant on the mid-shore, Bazillion snails!
Tiger moon snails clasping one another (mating?) and there were many 'sand collars' - which contain living moon snail eggs. There were several very large white moon snails that might be Egg-white moon snails, as well as one flatter red moon snail which is more definitely an Egg-white moon snail. I also saw Ball moon snails and one Lined moon snail.Weasel olive snails and I was glad to see some Fig snails. But we didn't come across any Bonnet snails. Other predatory snails seen include Noble volutes and Spiral melongena snails. There were also many scavenging whelks.
Orange-striped hermit crabs. There were many small Flower crabs swimming in the shallow water, and I saw one Spotted moon crab. There were many Horned ghost crabs foraging far away from us. I saw several Pearly anemones, which does seem to prefer sandy shores, and one Haddon's carpet anemone. I didn't see many burrowing worms though, only one Acorn worm. As the sun set, one large Painted sand star emerged (it did not have an orange underside).Window pane shells on bare sand on the mid-shore. I thought this odd as these clams are usually found in seagrass. I looked in deeper water and indeed, got glimpses of Spoon seagrass! Dark patches in deeper water might be seagrass! We may be able to see more if we come during a much lower tide.
Previous trips to these shore were in Nov 2011, Oct 2011, quick visit in Oct 2011, Jan 2010, first trip in Jan 2010.
