The diet composition of the Lycian salamander Lyciasalamandra luschani basoglui across both age and sex groups was studied. Specimens were collected from a small island in the Southeast Aegean Sea. The dominant prey group of juveniles consisted of Collembola, while Coleoptera dominated the diet of males and females. The number and size of prey items consumed by males and females of L. luschani basoglui were quite similar, while juveniles ate fewer items of much smaller size. The numerical abundance along with the four Measures of the size of prey permitted discrimination among males, females and juveniles. Although discrimination between adults and juveniles is expected due to dissimilarity in body size, discrimination between males and females remains inexplicable despite their similarity in body size. Future studies should be focused on understanding how and why prey choice differs between sexes in L. luschani basoglui.
