We have been looking for one species of salamander, called the red-backed salamander (Plethedon cinereus.) These salamanders have a red stripe down their back, which is how you can identify them from other species of salamanders. The salamanders also have a phase where their back is grey, and this phase is referred to as the lead back stage. These salamanders can live upon average, 10 years, and the most 32 years. We look for Red back salamanders because, they are the most populated salamanders in our area. Also, salamanders are great bio-indicators. Are science class would also like to find the yellow spotted salamanders. They are very rare. They are black with vibrant yellow spots. They are a little chubby in the middle. =====
