One of the main goals of benthic ecology has been to understand
the mechanisms regulating relationships between physico-chemical
parameter and organisms [19-22]. The present study shows that the
macrofaunal communities of three mangrove ecosystems exhibit
distinct variations. It is a characterized by temporal and spatial changes
in its population and distribution pattern seems to be fully governed
by the physico-chemical and hydrobiological characteristics of the
environment. Intertidal fauna at the study area have to cope with
harsh environmental conditions marked by high salinity, increased
