Species Summary
The Green Iguana (scientific name: Iguana iguana) is native to the tropical rainforests of North, Central, and South America. Known for their striking appearance and dinosaur-like features, they have become a popular choice for reptile enthusiasts worldwide. Green Iguanas are hardy creatures with the ability to adapt to various environments, making them well-suited for life in captivity. However, they do have specific care requirements that must be met to ensure their health and happiness.
Appearance & Colors
Green Iguanas have a distinctive prehistoric look, characterized by their robust body, agile legs, and clawed fingers. Their long, powerful tail serves as both a balancing aid and a defensive weapon. Along their spine, they feature a row of dorsal spines, which appear sharp but are safe to touch. Underneath their chin is a large dewlap, adding to their dinosaur-like appearance.
While the name “Green Iguana” implies a single color, these reptiles can display a variety of hues, including green, red, blue, yellow, white, black, and orange. The standard Green Iguana has a vibrant green coloration, often accompanied by darker bands of green on their tail and occasional splotches of pale brown or gray.
Average Green Iguana Size
Green Iguanas are one of the largest lizard species in the pet trade, with adults reaching an impressive 6 to 7 feet in length. Females are generally smaller, rarely exceeding 5 feet in length. A healthy adult Green Iguana can weigh around 20 pounds, making them a sizable addition to any reptile collection.
Lifespan
With proper care, Green Iguanas can have a lifespan of 15 to 20 years in captivity. In some rare cases, individuals have been known to live up to 25 years. Providing optimal care and regular veterinary check-ups can significantly increase the likelihood of a long, healthy life for your Green Iguana.
Green Iguana Care
While Green Iguanas are not considered a particularly challenging species to care for, they do have unique needs that must be met to ensure their well-being. The key to successful Green Iguana care is understanding their specific requirements and providing a suitable environment that closely mimics their natural habitat.
Enclosure Size & Setup
One of the primary challenges in Green Iguana care is providing an appropriately sized enclosure. As a general rule of thumb, the enclosure should be at least twice as long as the iguana’s body length. For adult iguanas, this means an enclosure measuring approximately 12 feet long, 6 feet wide, and 6 feet tall. Custom-built enclosures are common for adult Green Iguanas, as finding a commercially available enclosure of this size can be difficult.
Young juveniles can be housed in a 20-gallon terrarium, but they will quickly outgrow this space and require a larger enclosure within six months.
When setting up the enclosure, it’s essential to provide ample climbing surfaces and hiding spots for your Green Iguana. Create a network of branches, vines, and platforms to simulate their natural arboreal habitat. Live plants, such as hibiscus, can also be added for enrichment and grazing.
Temperature & Lighting
Green Iguanas require a warm environment with a temperature gradient that allows them to thermoregulate effectively. The cool end of the enclosure should have temperatures between 75 to 80 degrees Fahrenheit, while the warmer side should range from 95 to 100 degrees Fahrenheit. A dedicated basking spot with temperatures between 115 to 120 degrees Fahrenheit should be provided in one corner of the enclosure.
Use overhead lighting and heating elements to maintain appropriate temperatures, avoiding ceramic heaters or warming rocks, which can cause burns. Full-spectrum UVB lights are also essential for calcium synthesis and should be installed to cover the entire enclosure.
Humidity & Water
Maintaining humidity levels between 60 and 70 percent is crucial for Green Iguana care. Use a hygrometer to monitor humidity, and mist the enclosure as needed to maintain appropriate levels. A large, shallow water dish should also be provided, allowing your Green Iguana to soak and drink as needed. Regularly replenish and clean the water dish to prevent bacterial growth.
Green Iguana Diet
Green Iguanas are herbivores and require a diverse diet consisting of leafy greens, vegetables, and occasional fruit. Offer a variety of greens, such as collard greens, kale, mustard greens, turnip greens, romaine lettuce, and dandelion greens. Supplement with vegetables like squash, green beans, broccoli, zucchini, and carrots. Fruit can be offered once or twice a week as a treat but should be limited to avoid causing diarrhea.
To ensure your Green Iguana receives adequate nutrients, supplement their diet with calcium and multivitamin powders.
Potential Health Issues
Green Iguanas can experience a variety of health issues, including mouth rot, respiratory infections, skin infections, egg retention, and metabolic bone disease. Many of these conditions are preventable with proper care, including maintaining appropriate enclosure temperatures and humidity, providing a balanced diet, and ensuring a clean environment.
Regular veterinary check-ups are also essential for monitoring your Green Iguana’s health and addressing any potential issues early on.
Behavior & Temperament
Green Iguanas are generally easygoing and prefer a solitary lifestyle as adults. While young iguanas may live in groups and display protective behaviors, this social nature changes after their first year. As adults, Green Iguanas can become territorial, with males exhibiting aggression toward one another and occasionally toward females.
To avoid stress and aggression, it’s best to house Green Iguanas individually. A well-cared-for Green Iguana will spend its days basking and climbing, rarely spending time on the ground.
Handling Green Iguanas
With patience and slow socialization, handling Green Iguanas can be a rewarding experience. Initially, avoid handling your new Green Iguana, allowing them time to adjust to their new environment. Gradually introduce handling by hand-feeding and offering gentle touch.
Once trust is established, handle your Green Iguana gently and with care, supporting their body and keeping their face and tail pointed away from you.
Breeding & Baby Green Iguanas
Green Iguanas typically reach sexual maturity between three and four years of age. Breeding can be a challenging process, requiring an understanding of their reproductive cycle and appropriate environmental conditions. Females can lay between 20 to 70 eggs per breeding cycle, which should be incubated at a consistent temperature and humidity level.
Baby Green Iguanas have similar care requirements to adults, with adjustments to enclosure size and substrate. They can be housed in a 20-gallon terrarium initially, with paper towels or newspaper as a substrate.
Conclusion
Green Iguana care can be a rewarding experience for dedicated reptile enthusiasts willing to invest time and effort into meeting their unique needs. By providing a suitable environment, balanced diet, and regular veterinary care, Green Iguanas can thrive in captivity and offer years of enjoyment for their owners. With proper care, these fascinating reptiles can be a wonderful addition to your reptile collection.
