The Blue-spotted mudskipper (Boloephthalmus boddarti) feeds on the film of stuff growing on the mud surface. It moves its head from side to side to gather it. It lives in burrows. I've also learnt that where I see large ones, the mud is very VERY soft!
Yellow-spotted mudskippers (Periophthalmus walailake). It has pale spots on its body without any dark stripe, and a very handsome dorsal fin.
Giant mudskippers (Periophthalmodon schlosseri). It has dark 'racing stripes' along the body. And there were many of those too!
Kalak kambing (Finalysonia obovata).
nest mussels (Musculista senhousia) on the sand bar.

I last visited this shore in 2008 when I noticed some make shift buildings there being torn down. At that time I also learnt that there were rare mangrove trees at Seletar in the past. From "A Guide to Mangroves of Singapore", Peter K. L. Ng and N. Sivasothi (editors)
Botanists discovered a stand of Berembang (Sonneratia caseolaris) in the upper reaches of Sungei Seletar only last year (1998). Prior to this, only a single tree of this species in Woodlands was known of in Singapore! It is actually viewable in the distance from Lentor Avenue! This tree is thought to be associated with fireflies, and can tolerate freshwater conditions.And I found out what the word Seletar means. From the Wikipedia entry on Seletar
The Malay word seletar refers to the aboriginal coastal dwellers (orang laut) called orang seletar, who lived along the mangrove creeks of the Johor Straits and especially at the mouth of the Seletar River (which has since been dammed up to form the Lower Seletar Reservoir), hence the river's name. Later, Sultan Abu Baker of Johor is said to have taken these people from Seletar to Sungai Pulai in southwest Johor.
