**4. Conclusions**

Asry Beach in the Kingdom of Bahrain is typically an intertidal ecosystem characterized by both sandy and rocky substrate. As a public beach, visitors and other beach goers prefer the sandy portion rather than the rocky part. The rocky zone remains undisturbed where macroflora/fauna community contributes in the coastal food chain and in other ecological interactions. The emergent wet rock surfaces and crevices promote massive algal growth which serves as the feeding ground for many macrofaunal communities. Marine gastropods as natural inhabitants in the rocky biota are tolerable to changes in aerial temperature, thus maintains the dynamics in the rocky shores and ecological balance in beaches. The over-all status of diversity and individual species distribution determine the impact of both the biotic and abiotic factors on gastropod assemblage. Periodic biodiversity assessment and monitoring are initiatives for the protection, preservation and conservation of the natural habitat of gastropods.
