In juveniles, a pale vertebral stripe is often present, contrasting sharply with the bright green ground colour. The abdomen is white to creamy-yellow, except in the region of the forelimbs, where it is bright yellow in breeding males. Dark mottling may be present in the gular region of males (Du Preez 1996)
