Iguanas are herbivorous reptiles which can range from three to six feet in length, and inhabit tropical and desert biomes. They only appear as food in the Fallout universe.
They are one of the very few reptiles appearing in the Fallout universe.
Although never seen alive in-game, they are commonly hunted by humans and can be found in the form of various meals throughout the Capital and Mojave Wastelands, New California as well as the Commonwealth; these meals include iguana on a stick, iguana bits and iguana soup.
Iguana Bob Frazier, a shop owner in New California, owes his name to his iguana meat skewers.
