Popis: The present study was conducted on the gills structure and the gill surface area of 40 individuals of the Blue swimming crabs, Portunus pelagicus, and 40 Chinese mitten crabs, Eriocheir sinensis, specimens of the species were collected from the different regions of Shatt Al- Arab and North-west Arabian gulf. Both species were having eight phyllobranchiatesas of the same structure but different in length and surface area. The second gill in P. pelagicus shows major difference in shape from the other gills with missing platelets from one side of the filament. The results showed there were positive relationships between dry body weight with gill surface area, total number of platelets and number of platelets surface area in each gill. The gill surface area had no significant difference (p>0.05) with dry weight in the two species.
