First record of bicephaly in Lissotriton boscai (Amphibia, Caudata, Salamandridae)

Teratologies are frequent among vertebrates, but with differing prevalence among groups. For instance, cases of bicephaly are extremely scarce in amphibians, in contrast with other groups, like reptiles. Here we report the first case of bicephaly in Lissotriton boscai. The anomaly is a consequence o...
