|Abstract:||The genetic variability of the COI gene was studied in the common octopus, Octopus vulgaris Cuvier, 1797. A total of 222 individuals from 7 sampling sites were analysed with the aim of elucidating patterns of genetic variation along the coasts of Sardinia (Western Mediterranean). A total of 17 different haplotypes were identified with four principal haplotypes recorded in all locations. The pairwise Fst and AMOVA revealed a high gene flow and the lack of significant genetic differentiation among populations. All COI sequences were compared with those available in GenBank for the species; the results obtained show a high sequence divergence among O. vulgaris from different geographic locations and emphasize the need for more detailed phylogeographic and/or taxonomic studies to exclude the presence of cryptic species|
