The samples of Ocypodidae crab Dotilla blanfordi were collected on monthly intervals for the period of March 2007 to February 2008 from supra tidal zone of two different shores of Karachi coast i.e., Clifton and Korangi Creek. Sex ratio, population structure and ecology of these crabs were determined. For statistically analyzing the data 100 samples were taken randomLy in each month for each species from each site and measured their carapace length (C.L), carapace width (C.W), chela length (Ch.L), abdominal length (Ab.L) and abdominal width (Ab.W). Significant seasonal variations were observed in the abundance of total crabs sampled at Clifton and Korangi Creek of Karachi Coast.
