This indicates that only the South American populations may be the "true" green iguana. [7][43], Although green iguanas in captivity will eat meat if presented with it, excessive consumption of animal protein results in severe kidney problems and possible premature death.

The Galápagos tortoise (Chelonoidis nigra) and the Aldabra giant tortoise (Aldabrachelys gigantea) are considered the largest truly terrestrial reptiles alive today.

[13] Zoologists, such as Adam Britton, believe that such a diet containing protein is unhealthy for the animal's digestive system, resulting in severe long-term health damage, including kidney failure and leading to premature death.

[63][64] Historically, green iguana meat and eggs have been eaten as a source of protein throughout their native range,[65] and are prized for their alleged medicinal and aphrodisiac properties. [12] The wounded are more inclined to fight than uninjured prey. [1] A 6.17 m (20.2 ft) long individual was captured alive in Mindanao in 2011.

[30], Primarily herbivorous, green iguanas are presented with a special problem for osmoregulation; plant matter contains more potassium and as it has less nutritional content per gram, more must be eaten to meet metabolic needs.
A 2020 study also recovered both these subspecies as part of a distinct species, the southern Antillean horned iguana (I. insularis). As in all iguanas, the tail comprises much of this length, and the snout-to-vent length of most green iguanas is 30 to 42 cm (12 to 17 in). Other contenders for the largest crocodilian ever include the late Cretaceous period Deinosuchus, at up to 12 m (39 ft) and 8.5 t (8.4 long tons; 9.4 short tons). The species was first officially described by Swedish botanist Carl Linnaeus in 1758. [55] They commonly hide in the attics of houses and on beaches.
