Blue-spotted Salamander Blue-spotted and Jefferson salamanders frequently hybridize making identification difficult. The locationof the observation will indicate the likelihood of either a Jefferson (near Connecticut River NH) or blue-spotted salamander (distant from Connecticut River NH). However, genetic tests would be required to confirm whether a specimen was truly a blue-spotted or Jefferson salamander versus a blue-spotted / Jefferson hybrid. ©Mike Marchand photo
