Northern Two-lined Salamander - Eurycea bislineata

Description

A small (4 inches; 10 cm), slender salamander with a long tail. The body coloration is usually yellow or yellowish orange with 2 distinct dark lateral lines extending from eye to tail. The mid-dorsal region is often peppered with small black dots. Color variants occur in nature and include specimens that are more yellow than normal or have reduced black lines.

 

Reproduction

Eggs are attached to the underside of rocks on stream bottoms. Larvae may take several years to complete metamorphosis.

Juveniles

Aquatic larvae are dark brown with a series of light dots extending down the side beginning just behind the shoulder. The back may also have lighter coloration than the sides. The tail fin is reddish tan with black peppering. A dark line extends from the eye to the gills, which are well developed.

 

Habitat

Streams and brooks with rocky bottoms may be preferred. However, the species can be found in a variety of habitats. The author has found adults under flat stones near swampy habitat without running water, and in river flood plains (both in Ohio). Running water does not seem to be a necessity.

 

Food

A variety of invertebrates.

 

Range

A wide range throughout the eastern United States. The distribution of this species in Connecticut is quite extensive, with many known populations in every county. Only the Red-backed Salamander has a wider distribution in the state.

 

Status

Not protected by Connecticut.
