Some new cases of anomalies in wild Bufotes viridis from Western Poland are presented together with a discussion of their potential causes and a comparison with similar cases from the literature. The anomalies in question are color aberrations (pre- and post-metamorphic) and developmental pathologies (pre–metamorphic). The color anomalies include an ochre patch in a juvenile, leucism and albinism in both tadpoles and juvenile individuals. Developmental pathologies described in this paper include gigantism, edema, curvature of tail, and asymmetric bodies.
