Green Iguana

Overview

A large green lizard with a dorsal crest and long tail, a popular but demanding pet needing a huge enclosure and strict herbivorous diet.

History & Origin

The iguana is native to Central & South America. It belongs to the family Iguanas, a lineage of lizards distributed across those regions and kept both in the wild and by specialist reptile keepers.

Temperament

It shows the typical temperament of its group—research the species for handling guidance.

Care & Husbandry

Iguanas are primarily herbivorous as adults, requiring a varied diet of leafy greens, vegetables and limited fruit; juveniles are more insect-tolerant. They need very large enclosures, strong UVB, high basking temperatures and climbing structure. Green iguanas in particular grow large and demand committed long-term husbandry.

Health & Lifespan

Key risks are metabolic bone disease, kidney disease from low hydration, and impaction. Growing iguanas need careful calcium:phosphorus balance and UVB; males can become aggressive in breeding season. In captivity a healthy individual may live around 15–20 years.

Popularity & Recognition

Green iguanas are icons of the pet trade and invasive in Florida and the Caribbean; their dramatic dewlap, whiptail and third 'eye' (parietal eye) make them unmistakable.
