We analyzed the trophic spectrum of 86 Rana ridibunda individuals from Sarighiol de Deal, Tulcea County, Romania. The most important preys are represented by the Coleoptera, Diptera and Homeoptera (Cicada). Certain variations in feeding appear during the ontogenetic development, the juveniles feeding the most intensively, in the spectrum of which appear the lipid-rich Ephemeroptera larvae. The food diversity is negatively correlated with the feeding intensity, the males having the maximum diversity. The majority of preys have a terrestrial origin. The presence of different size preys indicates an opportunistic feeding
