Tiger Salamander
Size: Can grow upwards of 13 inches in length.
Habitat: Marshes, damp forests, and higher altitudes near ponds.

The largest land-dwelling salamander in the U.S., the Tiger salamander is named for its striped pattern. Loss of habitat, acid rain, pollution and the addition of game fish all negatively affect Tiger salamander populations.
