There is no reason to expect that red-backed salamanders can't also reach these ages. Biogeographic Regions; nearctic.
Life Cycle The western red-backed salamander mates from November to December. It has a lifespan of 12 to 15 years in the wild, and it may grow to 5 in (13 cm) in length. Red-spotted Newt.

Losing a tail is not a problem as it can always grow a new tail, just like the lizards.
Around October, females lay an average of 70 eggs in hidden areas in and around streams. The usual life cycle of this species includes three distinct post-hatching stages: (1) aquatic larva, (2) terrestrial (juvenile) eft, and (3) aquatic adult. Courtship between males and females begins in spring and continues through autumn. Life-cycle and mating of the Red Eft.
In its place, a new tail will eventually grow, though this new tail may be duller in color.
Eggs hatch in early winter. Young red salamanders are called larvae and have gills. As amphibians, salamanders can breathe and live in water or on land. But instead of redeveloping the gills they had as larvae, they spend the rest of their lives breathing through their lungs at the surface of the water. Salamanders are excellent indicators of stream health, because they are very sensitive to stressors such as pollution, deforestation, stream erosion and mine drainage. Lifespan for the eastern red-backed salamander is approximately 25 years in human care. Eastern red-backed salamanders can evade predators by dropping all or part of their tail in the event of an attack. Giant salamanders weigh up till about 63 kg.
), then later in life come back to the water again to breed as an adult. The "redback" phase consists of a gray or black body with a red or orange stripe down the back, extending from the neck onto the tail. The red-spotted newt has a very interesting life cycle.
