The sampling area was divided into three transects lines. The first transect 1 was located just opposite to the shore
laboratory, Centre of Excellence in Marine Biology, University of Karachi. The second transect was at a distance of 1.5 km
away from transects 1 towards east and third transect was 1.5 km away from transects 2 or 3 km away from transects 1.
Each transect stretched over three tidal zones, i.e., low tide level (LTL), mid tide level (MLT) and high tidal level (HTL).
