Sediment texture plays an important role in the ecology of benthic
invertebrates [40,41]. The pelagic larvae of macrobenthic organisms
before finally settling down at the bottom have to cross many barriers,
and each type of bottom deposit will attract a very limited and selected
set of species [42]. A common concept in benthic animal-sediment
relation is that the feeding type of the infauna is in one way correlated
to the sediments [43]. Deposit or detritus feeders constitute an
important and often dominating part of macrobenthic invertebrates
[44]. Sediment character has been identified as one of the driving forces
in determining the macrofaunal communities. At station I, species
diversity is negatively correlated with sand (r=-0.986) while in station
II and III, positive correlation is obtained between density and silt
(r=0.984 and r=0.887) at p
