There's a thin sliver of mangroves at Kranji behind heavy industrial sites. I wondered how it is doing since I last visited in Feb 2011.
The patch of rare rare Beccari's seagrass (Halophila beccarii) is still there.
Mangrove horseshoe crab (Carcinoscorpius rotundicauda)and many tiny ones in shallow pools of water among the trees. The Nature Society (Singapore) runs a programme that regularly monitors the horseshoe crabs at Kranji. Usually, members of the public can volunteer too for this programme. NSS has also published about their work on horsehoe crabs at Kranji.
ribbon worm (Nemertea) that I've not seen before.
Onch slugs (Family Onchidiidae) under this stone.
porcelain crabs (Family Porcellanidae). While most scuttle madly away, some will flatten out and stay still in the hope that you overlook them.
Mangrove whelk (Littoraria melanostoma) hunker down at low tide. They use a bit of slime to glue the lip of the shell to a hard surface, then retract into the shell and seal themselves up with the 'door' or operculum. This is why we should not pick snails off the rock or tree. You can't glue them back on and when the tide comes in they may get washed away or be eaten by predators that come in at high tide.
Workshop on Bryozoans and Hydroids next month. So I scrutinised all hard surfaces. For the first time, I noticed that there were all kind of seaweeds! But alas, nothing that I recognised as bryozoans.
Nerite snails (Family Neritidae) that don't look like those I usually see. Well, there are 19 recorded species of Nerites on our shores and I haven't been paying close attention to those found in mangroves.
Spotty sea anemones which Dr Daphne first found at Sungei Buloh. There were also many other small common sea anemones like the Lined bead anemone (Diadumene lineata) and Bead anemones (Anthopleura sp.).
Mangrove murex (Chicoreus capucinus) firmly wrapped around barnacles. This snail is a Drill and does drill holes through the shells of prey like barnacles. It takes a long while for the Drill to pierce the shell, so you shouldn't disturb them.
EcologyAsia website has lots of info about lizards and geckos of all kinds. But I'm not too sure what this is. Wouldn't it be great if it was the Maritime gecko? I didn't even know we had such a gecko.
my last visit two years ago. The mangroves here are suffering seriously from erosion. Erosion is a major issue in all our other mangroves in the Johor Strait, from Lim Chu Kang, Sungei Buloh to Mandai.
a separate post about the rubbish situation here.
