Southern Crested Newt belongs to family Salamandridae and distributed in Gilan, Mazandaran, parts of Ardabil, East and West Azarbaijan Provinces. They are identified by dark brown color in dorsal, dorsal crest in males; tail compressed laterally, ventral surface head and body with dark spots. Morphologic and 25 morphometric characters (accuracy 0.01mm) were studied in 57 specimens (14 females, 24 males, 19 larvae) from Mazandaran Province, preserved and depositedin Zoological Museum of Golestan University. Males have dorsal crest and a bright silver band along the sides of the tail. Snout-vent lengthin males were 47.59-62.35, in females 57.76-64.05, and in larvae 32.73-39.03. Ratios of forelimb to hindlimb lengths of larvae were 0.79-0.99 (0.88±0.053), in males 0.75-1.03 (0.91±0.079) and in females 0.81-1.07 (0.93±0.078). Ratio of head width to head length in larvae 0.65-0.90 (0.79 ±0.072), in males 0.65-0.99 (0.81±0.084) and in females 0.68-0.99 (0.84±0.097). Ratios of tail to total lengths were 0.47-0.54 (0.51±0.019) in larvae, 0.45-0.52 (0.48±0.021) in males and 0.45-0.51 (0.48±0.022) in females. Ratios of head to snout-vent lengths were 0.21-0.29 (0.24±0.019), 0.22-0.31 (0.26±0.022) and 0.23-0.30 (0.24±0.020) in larvae, males and females respectively.
