The term giant green iguana refers to the giant lizards. They are said to be giants because they grow up to five to six feet in a span of four to five years. If you prefer not to have a big lizard under your care, then do not opt for a giant green iguana. There are no dwarf versions of this species so you must understand from the very start that green iguanas by nature can grow really large. You cannot by all means make an iguana a dwarf version not unless you expose it to severe chronic malnutrition and then to continuous hypothermia.
