Examing archives and spotted this – Adrian Loo and I were with some undegrads at the time, setting them up for their research work at Sungei Mandai Besar mangrove on 23 Dec 2005. Something alerted me, so I stopped the student who was about to peer inside a bush. I walked around and there it was, an Equatorial Spitting Cobra (Naja sumatrana ) inside the bush. It glid away, disturbed to the back mangrove subsequently. And there were two. See Ecology Asia for notes on the species.
