|A Striped hermit crab (Clibanarius infraspinatus) |
foraging on the shore.
Lush seagrass meadows grow here in a narrow fringe along the beaches. The highest portion was peeping out during this not-so-low tide.
Spoon seagrasses (Halophila ovalis) on this shore have very large leaves. Those I saw today seemed fine, without any bleaching or burnt leaf blades.
Leaf porter crab (Family Dorippidae) under it. As its common name suggests, it has two pairs of legs that are short and bent permanently over the back. These legs are tipped with hairy pads to cling onto a leaf. Two other pairs of legs are longer and fringed with hairs. These fringed legs are used like paddles to swim slowly about. It may also hide under shells or bits of rubbish.
Lined nerite (Nerita articulata).
tubes of worms. A sandy shore might seem barren, but many animals can live hidden beneath, leaving few signs of their presence.
Orange fiddler crabs (Uca vocans). Looks like an unlucky male has lost his enlarged pincer. Possibly in a fight? Males use their enlarged pincers to attract females (which have two small pincers) and intimidate other males.
Onch slugs (Family Onchidiidae) on the rocky shore too, despite the heat.
Drills (Family Muricidae), laying egg capsules.
Bakau mata buaya (Bruguiera hainesii) and it seems to be well. Lots of fallen flowers and one propagule.
a security barrier put up to stop illegal immigrants from landing on the beach.
Sea morning glory (Ipomoea pes-caprae) is very pretty too! According to the late Prof Ivan Polunin, this plant is the most important coloniser of many tropical beaches around the world. Its creeping rooting stems often form dense patches which hold down the sand and produce humus.
FREE evening guided walk at the Pasir Ris mangrove boardwalk later this month.
