Age structure and some growth parameters of Bufo viridis from the Giresun Island and Giresun province in Turkey were studied by skeletochronology. We studied 56 specimens (41 female, 15 male) from island and 44 (5 female, 39 male) from mainland population. In both populations, age at sexual maturity was 2-3 years in both males and females. Age was ranged from 2-8 years for females and 3-6 years for males in island while 4-7 and 3-8 years in mainland population, respectively. Males and females did not differ in the mean age while SVL and weight were significantly different between males and females in two populations. In addition, we found positive correlations between age and SVL in both sexes in two populations.
