title: Corresponding defects in the dorsal fin and in the male breeding crest ofTriturus alpestris.
abstract: In a wild population ofTriturus alpestris several adult males with an incomplete breeding crest were found. Among the offspring from this population larvae with defects in the dorsal fin were observed. Neither the pigment cells nor the spinal ganglia appear affected in the deficient trunk region of larvae and adults.
