Molecular diversity of dolphinfish (Coryphaena hippurus) shows the merging of endemic and widespread haplotypes in the Mediterranean Sea

Molecular data on Coryphaena hippurus (Linnaeus, 1758) from western and centralMediterranean Sea were reported and compared. The aim of the study was to study the mitochondrialmolecular structuring of the species at different geographical scales: localities, sub-basins, and oceans.Results show the absence of a sharp population structure inside the Mediterranean Sea, and the isolation ofthe Mediterranean dolphinfishes from those inhabiting the Atlantic Ocean
