History and origin
Native to South America. One of the most popular lizards, but DEMANDING: 2 m long · intense UVB · strictly herbivorous diet.
Temperament and character
Reptiles are NOT social the way mammals are. They tolerate handling but do not seek company. Trust is earned with patience.
Living together
Children: depends on the species + educational handling. **Other pets:** avoid — two-way risk. **Other reptiles:** depending on the species, separate terrariums are best.
Life stages of the Iguana Verde
Each stage has its own care priorities. Life expectancy: 12-20 años.
Hatchling/Neonate
0-6 months
High UVB and a hot spot of 32-35 °C, 70% humidity; a 100% herbivorous diet (leafy greens) with calcium to prevent MBD.
Juvenile
6 months-2 years
Rapid growth: calcium-rich leafy vegetables, daily UVB; a tall terrarium with branches.
Subadult
2-4 years
A large vertical enclosure, thermal gradient and strong UVB; a varied herbivorous diet, hydration.
Adult
4+ years
Large size (1.5 m): a wardrobe-sized enclosure, avoid burns from accessible lamps; monitoring of egg retention.
Care
Terrarium: minimum size according to species (consult species-specific guides). UVB is mandatory for diurnal species.
Temperature: day/night gradient · warm zone vs cool zone for thermoregulation.
Humidity: according to species (rainforest 70%+ · desert 30-50%).
Diet: species-specific · insectivores, herbivores and carnivores vary radically.
Veterinarian: exotics vet (a regular vet will NOT do). Annual check-up.
Care in detail
Nutrition
Strictly herbivorous: varied leafy greens and vegetables, no animal protein. Calcium supplementation as directed by the vet. Giving it insects or protein is a common mistake.
Grooming
Careful handling, baths/misting to aid shedding and maintain humidity, and nail care. Watch for retained shed on the toes and tail.
Training
It is not a social animal: it tolerates handling but does not seek company. 'Taming' means earning its trust with patience and regular, gentle handling to reduce stress.
Exercise
It needs a large terrarium (an adult can exceed 2 m) with branches to climb and thermoregulate; room to move and both warm and cool areas.
Breed-specific health
Lack of UVB (rickets, MBD), parasites, respiratory infections from incorrect humidity. Life expectancy 12-20 years when well cared for.
Health predispositions for this breed
Conditions this breed is more predisposed to. Knowing about them helps with prevention and early detection. A predisposition does not mean the animal will develop them.
