dc.description.abstractRocky shores are considered heterogeneous environments due to their composition and ‎structure. Therefore, they support numerous habitats for flora and fauna. Organisms ‎found on rocky shores are facing intense physicochemical conditions during tidal ‎changes from upper to lower intertidal zones. Total (N=1888) specimens were collected ‎on seasonal basis from intertidal zone during low tide from two rocky sites of Karachi ‎coast, Buleji and Sunehri during January 2017 to December 2017. The highest number ‎of individuals (N=1041), were recorded from Buleji than Sunehri (N= 847). The seasonal ‎abundance in Mollusca were measured as (36.84%), (63.67%), (25.08) and (40.38%) ‎from Buleji while from Sunehri (45.16 %), (46.01%), (48.65) and (42.79 %) during pre-‎monsoon, south-west monsoon, post monsoon and north-east monsoon season ‎respectively. Group Arthropoda, Mollusca and Echinodermata were shows the highest ‎abundance of the species at both sites as compare to other groups. The highest diversity ‎index from Sunehri (H'=0.64) was measured in north-east monsoon season meanwhile, ‎‎(H'=0.61) was measured in post monsoon season from Buleji coast. Evenness index ‎‎(J'=0.25) in pre-monsoon season from Buleji and (J'=0.28) in south-west monsoon season ‎from Sunehri coast . Season shows the great abundance of species as compare to other ‎seasons. No significant correlation was observed in between seasons, water temperature ‎and salinity with macrofauna groups at both sites. ‎
