Since the work of C. Niebuhr, a Danish biologist in the 18th century, the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of fishes of Persian Gulf based on literature and taxon occurrence data obtained from natural history and new fish collections. The total confirmed fish species of Persian Gulf comprise 744 species, 131 families, 445 genera and 27 orders. In the class Chondrichthyes, the most diverse family is Charcharhinidae with 23 species (41.89%), followed by Dasyatidae with 15 species (31.08%). Within the class Actinopterygii, Gobiidae with 65 species (9.70%), Carangidae with 45 species (6.27%), Serranidae with 25 species (3.73%), Apogonidae with 25 species (3.73%), Lutjanidae with 23 species (3.43%) and Blenniidae with 23 species (3.43%) are the most diverse families in the Persian Gulf.

The Persian Gulf lies entirely north of the tropic of The Persian Gulf comprises a large shallow Cancer and therefore, it can be considered as a sub- marine environment with wide fluctuations in tropical region. It has been located within the large, temperature and salinity due to its climatic regime. arid East Asian land mass having more tropical Hence, its fish species must be capable of climate in summer, and more temperate climate in withstanding the stress of osmotic and temperature winter (Michel et al. 1986; Sheppard 1993).

Seawater Persian Gulf is semi-enclosed about 1,000km long temperatures of the Persian Gulf can exceed 34°C in and 200-300km wide with an average depth of 36m summer and might be less than 15°C in winter (Rezai and a maximum depth of 120m (Michel et al. 1986). et al. 2004).
