How long does a Iguana Verde live?

The life expectancy of the Iguana Verde is 12-20 años. A good diet, adequate exercise, annual veterinary check-ups and preventive care can help reach the upper end of that range.

How much does a Iguana Verde weigh?

An adult Iguana Verde weighs between 4-8 kg, depending on its sex, genetics and condition. It is grande.

Who is the Iguana Verde NOT recommended for?

It isn't the right breed for: Homes with young children without supervision. People without prior experience (consult an exotics vet first). A life spent 100% in a small terrarium (cruel). It's important to choose a breed that's compatible with your lifestyle.

Is the green iguana suitable for beginners?

No. It is a demanding pet: it can grow up to 2 metres, needs strong UVB, a thermal gradient, a strictly herbivorous diet and an exotics vet. It is not recommended without experience.

What does a green iguana eat?

It is strictly herbivorous: varied leafy greens and vegetables, with calcium supplementation. Giving it insects or animal protein causes kidney problems; this is a frequent mistake.

Why is UVB light so important?

Without UVB it cannot synthesise vitamin D or fix calcium, and it develops metabolic bone disease (deformities and fractures). The UVB tube must be replaced periodically even if it still lights up.

How much space does it need?

A lot. An adult can exceed 2 metres in length and requires a large terrarium with branches to climb and thermoregulate; a small terrarium for life is abuse.

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.
