physeteris obtained from the NE Atlantic Ocean, F st at the intraspecific level was calculated only for the comparison of specimens collected from stranded sperm whales along the coast of the Adriatic Sea (of Ionian Sea origin 31 ) and those carried by the dwarf sperm whale ( Kogia sima ) from the Tyrrhenian Sea, with the finding of a generally low and slightly significant level of differentiation ( F st ≈ 0.012, p = 0.03) (Table 2 ).
