None of the previous genetic analysis found significant differences within the Mediterranean. However, a more exhaustive analysis is needed inside this sea. In this sense, we have analyzed the mitochondrial control region sequence variability of three Mediterranean locations: Libya (n = 22), Tunisia (n = 23) and Malta (n = 12). Additionally a sample from the Gulf of Cadiz (n = 24) in the East Atlantic Ocean was also included in the study. The AMOVA analysis revealed slightly (Fst = 0.013) but significative genetic differences (P < 0.000) for the Malta location, probably due to its small sample size (n = 12). In the other hand, when this location is removed from the analysis, no differences where found among the three remaining location (Fst = 0,005; P = 0,097), neither when they were compared with the previous genetic data from the Mediterranean (Fst = 0,002; P = 0,149).
