The stomach contents of two Cuvier's beaked whales (Ziphius cavirostris) stranded along the eastern Adriatic coast were examined. One was a male stranded in 2004 and the other was a newborn stranded in 2008. Milk was found in the newborn's stomach. The prey of the male was only cephalopods belonging mainly to the Teuthoidea. Five families and seven species were identified. Octopoteuthis sicula represented about 50% of estimated prey weight and Chiroteuthis veranyi was the most frequent species (estimated from the quantity of lower beaks). Three species are not listed in the Adriatic fauna, while the other species are found in middle and lower slope cephalopod assemblages in the southern Adriatic Sea.
