Chinese water dragons can grow up to 1 m (3. 3 ft) in total length, including tail, and can live from ten to fifteen years. Coloration ranges from dark to light green, or sometimes purple with an orange stomach. Diagonal stripes of green or turquoise are found on the body, while the tail is banded from the middle to the end with green and white. Their undersides range from white, off white, very pale green, or pale yellow. But their throats are considered to be more attractive, which can be quite colorful (blue and purple, or peach), some with a single color, some with stripes. Adult males have larger, more triangular heads than females, and develop larger crests on the head, neck and tail, and are larger in general. The tail, slightly over two-thirds of the entire body length, can be used as a weapon, for balance, and to assist swimming.
