Varanus kordensis, the Biak tree monitor, is a member of the Varanidae family found on Biak Island in Indonesia. It is also known as the Kordo tree monitor. Long considered a subspecies of the emerald tree monitor (V. prasinus ), most authorities now treat it as a separate species.
The Biak tree monitor is mainly yellow-green, although in captivity specimens frequently lose their yellow pigment and become turquoise in color. It has a black netted pattern which is visible on its back. It reaches a total length of up to 90 cm.
