Teeming with sand dollars and countless Button snails, Wai and I check out a stretch of sandy shore at East Coast Park this evening.
This stretch of sandy shore at the northern end of East Coast Park is quite large even at a not-so-low tide day like today.
Button snails (Umbonium vestiarum). They leave tiny tell-tale depressions on the sand. And when we gently scrape away at the surface, we can immediately see countless snails. In some places, even footprints on the sand reveals the tiny snails just beneath the surface.
Ball moon snails (Polinices didyma). There were also lots of Spiral melongena (Pugilina cochlidium) and a few Drills (Family Muricidae) too! I only found one Olive snail (Family Olividae) today.
Lined whelks (Nassarius teretiusculus?). These are probably scavengers and not predators. There were also many Tidal hermit crabs (Diogenes sp.) and some small Striped hermit crabs (Clibanarius infraspinatus). As well as lots of small to tiny Cake sand dollars (Arachnoides placenta).
tubeworm tubes festooned with debris. It was hard to photograph the animals living in the tubes as they sporadically peeked out now and then.Peachia anemones (Peachia sp.) and Wai pointed out some Acorn worms (Class Enteropneusta). There were also a few signs of Sand bubbler crabs (Scopimera sp.).
oysters (Family Ostreidae). But the rocks were disconcertingly devoid of snails, sea slaters, limpets and crabs. We could hardly find any of these. Oh dear. I wonder why? The shore was not as lively as on our last trip here in Aug 2012.
