Abstract

Records of malformation in amphibians have significantly increased on a global scale. The main causes of malformations are linked to environmental contaminants, and records in preserved environments are uncommon. We reported malformations in three anuran species belonging to three families:Crossodactylustimbuhy(Hylodidae),Proceratophrysschirchi(Odontophrynidae) andThoropamiliaris(Cycloramphidae). All records were found within the Reserva Biológica Augusto Ruschi, a well-preserved protected remnant of Atlantic rainforest located in the mountains of the state of Espírito Santo, southeastern Brazil. The malformations detected were hemimelia (long bone shortened) with ectrodactyly (digit absent) and brachydactyly (digit shortened) inC.timbuhy, microphtalmia (small eye) inP.schirchiand ectrodactyly inT.miliaris. Further studies are recommended to enable a better understanding about the incidence and causes of malformations within preserved areas.
