About Giant Invasive Iguanas
GII is a large arboreal (tree-dwelling) species of lizard and is native to Central, South America and the Caribbean. It can reach a total length of 2 meters and weigh an average of 9 kilograms. Most GIIs are predominantly green in colour. However, the coloration is variable including black, grey, white, bluish, green or brown GII.
GII has very long tail which is 2 or 3 times the length of the body. The toes are long with thin curved claws for climbing. GII has spines along the head, neck and back, reaching up to its tail. It has a fold of loose skin hanging below the throat which is called the dewlap. GII also has large scale (leathery covering of their eardrums) on both sides of the neck. The large scale and the dewlap are key ways to differentiate between the GII and the native Fijian iguanas.
