David, if I may add, the mangrove tree species is a Brugueira species. It inhabits the higher levels of the mangrove coastline. Known locally as 'bakau putih', this mangrove species is distinguished from the others by its greyish thick and dense roots.
These photos remind me of those bygone fieldtrip days when we wore latex boots and squelched and waded through the mudflats. The fiddler crabs were the first to dart out of sight but the mudskippers are easier to spot.
Ken: Yeah you are right, the mangrove roots act as a barrier to minimise impact of the waves.
Khoas: We have our own version of mr salties here in the Peninsular but he is not so big compared to mr salties of Borneo. :P
