Description:
Description: English: Chinese water dragons can grow up to 90 cm (3 ft) in length for males and up to 60 cm (2 ft) for females but 2/3 of this is tail length. Colouration ranges from dark to light green. 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 dark brown. Their undersides range from white, off white, very pale green, or pale yellow. But more attractive are their throats, which can be quite colourful (generally yellow, orange, 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. Like many other reptiles the Chinese water dragon possesses a small, iridescent, photosensitive spot between their eyes referred to as the pineal gland (or colloquially as the third eye) that is thought to help thermoregulate their bodies by sensing differences in light to assist with basking and seeking shelter after sunset.[1] Since it recognizes differences in light, the pineal gland can also help the lizard avoid predation from birds and other aerial threats.
