Description
Northern two-lined salamanders grow up to four inches long (Quinn, 2020). They are gold with two dark lines running from behind each eye to the end of the tail. Darker mottling is sometimes present. They have laterally flattened tails.
Habitat
These salamanders can be found in or around streams, or hiding within moist forests.
Behavior
This species can often be found under rocks and logs during the day. They emerge and move around in the dark or while it is raining. They eat small invertebrates, including insects and arachnids.
Two-lined salamanders breed in the spring. Eggs are laid under debris in moist areas or underwater. These hatch into aquatic larvae. Predators include snakes and birds.
