Description

Eurycea lucifuga can be red, dull yellow, or orange with a belly that ranges from yellow to white (Bishop 1994). The back and sides of the head, trunk, and tail contain small rounded or irregular black spots (Bishop 1994). These spots can sometimes form a dorso-lateral linear pattern (Bishop 1994). This salamander is slender and has a blunt snout (Petranka 1998). The largest part of the head is located immediately behind the eyes (Bishop 1994).

Adult Eurycea lucifuga are 100-200mm in total length (Petranka 1998). A survey by Hutchison (1958) found that adult males are mature at 46mm SVL and females are mature at 48mm SVL. Males can be identified externally by a swollen snout area by the nasolabial grooves (Bishop 1994). Additionally, males posses more developed cirri than females (Bishop 1994). Juveniles are less pigmented then adults, and are yellowish in color (Conant and Collins 1998). Juveniles also have a shorter tail (Conant and Collins 1998).
