PHYSICAL DESCRIPTION: The dorsal band is bright greenish-yellow to orange- yellow or brownish, not strongly suffused with dusky, but with small black flecks are often arranged in a linear series along the mid-line. The sides below the dorsolateral dark strip are uniformly grayish or mottled extending to the upper level of the legs. There is a glandular protuberance on base of the tail above in the adult males. The length can be up to 97 mm *1009*.
REPRODUCTION: This species resorts to water during the egg-laying season *1009*. The courtship occurs in the fall. The eggs are laid in the winter and spring. The eggs are deposited on the undersurfaces of rocks, logs, usually in running water. The female remains with eggs until hatching the aquatic larvae *865*.
BEHAVIOR: This species inhabits brooksides and hides beneath stones and logs in well saturated soil. This species swims freely *1009*. It lives near spring seepages and streams in hardwood forests and swamps *1014*. It is very moisture dependent, and retreats to moist cover during dry periods *917*. Over 98% of the activity is confined to dark hours and is correlated with precipitation. It occurs along streams and in swamps around lakes *965*. This species requires moisture and a temperature of 12.8 degrees C to trigger spring breeding migration *857*. It hibernates with the approach of winter, lowered soil temperature, and/or adverse moisture conditions *986*.
ORIGIN: This species is native *1008*.
