Mangrove swamps

Here is a photo of mangrove swamps at Wetland Park.  This is a habitat for many species.  Something like 80% of fish species spend some part of their life in the mangroves.  The mangroves are tolerant of brackish water (that is part salt water and part fresh water).  This is a place where mudskippers live amongst the fiddler crabs.  Every tide brings in more materials from the sea (hopefully not crude oil) which the numerous species can feed upon.  This attracts hungry birds as well.  There is a food web here.  The crabs will eat the dead fish, the birds will eat the crabs, the birds of prey will feed on the birds and the fish.   So it is all inter-related.
