Lizards captivate us with their ancient lineage and diverse forms, offering a unique window into the cold-blooded world. For those seeking a truly impressive pet, the allure of Big Lizard Pets is undeniable. Imagine sharing your home with a creature that commands attention, a living dinosaur in miniature!
The reality is, while undeniably impressive, owning a big lizard pet is a significant undertaking. It’s crucial to understand that their size and strength demand respect, specialized care, and a considerable commitment. However, for the prepared and dedicated reptile enthusiast, these magnificent animals can be rewarding companions. Once you grasp their specific needs regarding habitat and care, even the largest species become manageable.
The sheer power of big lizard pets is a factor that sets them apart from smaller reptiles. This very power, while awe-inspiring, adds complexity to their care. Their size translates to substantial space requirements, and their strength necessitates secure enclosures and careful handling. The “WOW” factor is certainly there – envision a reptile that occupies an entire wall or even a room in your house!
However, it’s essential to be realistic: big lizard pets are definitely not for everyone. This guide will explore the world of giant pet lizards, helping you determine if you’re ready for the responsibility.
Most commonly kept big lizard pets fall into two primary categories: monitor lizards and iguanas. We’ll delve into popular species within these groups, along with a noteworthy exception. It’s crucial to remember that large lizards are generally recommended for experienced reptile keepers only.
Let’s embark on an exploration of the best big lizard pets available, examining their unique characteristics and care requirements to help you make an informed decision!
Exploring the Realm of Monitor Lizards as Big Lizard Pets
Our first category of big lizard pets is the impressive monitor lizard. Known for their intelligence and size, monitor lizards represent some of the largest and most captivating reptiles you can own.
Before we delve into specific recommendations, it’s vital to understand the fundamental needs shared by all monitor lizards. These are non-negotiable aspects of their care:
- Deep Substrate: Monitors are natural burrowers and require a thick, deep substrate (several feet deep) to satisfy this instinct and feel secure.
- Expansive Habitat: “Large” is an understatement. Monitors need huge habitats, often requiring dedicated rooms to allow for adequate roaming and exercise.
- Multiple Heat Sources: They are ectothermic and rely on external heat. Provide several heat lamps, ensuring they are inaccessible to the lizard to prevent burns.
- Water Feature: A large, filtered pond or water feature is essential for soaking, drinking, and maintaining humidity.
- Ample Food Supply: Monitors are voracious eaters and require copious amounts of food to fuel their active lifestyles.
Recommendation #1: Savannah Monitor – A Robust Big Lizard Pet
The Savannah Monitor (Varanus exanthematicus), also known as the Bosc monitor, is often considered a medium-sized lizard within the big lizard pet category. Resembling a large tegu more than other monitors, the Savannah Monitor possesses a sturdy build and intriguing appearance. Despite their seemingly docile appearance, Savannah Monitors can be quite demanding.
Growing to over three feet in length, Savannah Monitors require a substantial habitat to accommodate their size and energy levels. Originating from the arid landscapes of the African savannah, their enclosure must replicate this dry, warm environment.

Savannah Monitors are known to grow to the size of their enclosure, emphasizing the need for a large habitat even for juveniles. Ideally, the enclosure should be a minimum of six feet in each dimension. Many dedicated owners allocate an entire room to meet the spatial needs of this reptile.
In their natural habitat, Savannah Monitors are active predators, constantly exploring and moving. They are avid diggers, requiring a heavy, deep soil-based substrate that is stable and prevents tunnel collapse.
While capable of becoming accustomed to handling, friendliness is not their natural disposition. Therefore, experienced handlers are essential to manage their behavior effectively.
Their bites can be aggressive and inflict painful wounds, sometimes requiring stitches. With consistent and patient training, some Savannah Monitors can be harness-trained, but this is not guaranteed due to individual personality variations.
The right Savannah Monitor, with a dedicated and experienced owner, can be a rewarding pet. However, many are unfortunately surrendered to rescues due to owners underestimating their care needs and temperament.
Recommendation #2: Nile Monitor – The Powerful Giant Among Big Lizard Pets
The Nile Monitor (Varanus niloticus), the largest lizard native to Africa, is a truly impressive big lizard pet. Reaching up to five feet in length and weighing up to 45 pounds at maturity, the Nile Monitor demands respect and significant resources.
Young Nile Monitors are highly active, exhibiting a love for climbing and exploration. Unlike Savannah Monitors, their activity level may slightly decrease with age, but they remain energetic throughout their lives.
Nile Monitors are not known for their docile temperaments. Even with consistent handling and training from a young age, a Nile Monitor can inflict serious injuries, potentially requiring emergency room visits for stitches simply from routine handling attempts.
Their arsenal includes massive, sharp claws, razor-sharp teeth, and a powerful tail capable of delivering painful whips.
Experienced reptile owners should prioritize acquiring captive-bred Nile Monitors and commit to consistent handling throughout their lives. Even with dedicated effort, their temperament remains unpredictable.
Nile Monitors possess a high metabolism and require frequent feeding to sustain their energy levels. Their athletic nature and constant movement within their expansive habitat necessitate a substantial caloric intake.
Recommendation #3: Black-Throat Monitor – A More Temperamentally Forgiving Big Lizard Pet
Among big lizard pets, the Black-Throat Monitor (Varanus albigularis) presents a more manageable option for keepers with some, but not extensive, experience.
While not recommended as a first lizard, the Black-Throat Monitor can be a suitable choice if you have the space (and you will need a dedicated room!). They are generally considered less challenging temperamentally than Nile Monitors.
Black-Throat Monitors are indeed large, surpassing Savannah Monitors in size. They can reach up to six feet in length and weigh between 50 and 60 pounds, solidifying their status as big lizard pets.
While capable of inflicting damage due to their size and strength, Black-Throat Monitors generally possess a more docile personality. Injuries are often accidental, such as scratches from their claws while climbing on their keepers.
Providing an appropriate diet and habitat, coupled with consistent handling, is crucial for a Black-Throat Monitor to thrive and exhibit its typically non-aggressive behavior.
Recommendation #4: Asian Water Monitor – The Intelligent and Interactive Big Lizard Pet
If you seek a big lizard pet with which you can truly bond and interact, the Asian Water Monitor (Varanus salvator) stands out.
Regarding temperament, the Asian Water Monitor surpasses other giant monitor species. They are known for their playful and curious nature. While still possessing the potential to inflict harm due to their size, intentional aggression towards their keepers is less common compared to other large monitors.
Beyond their agreeable temperament, Asian Water Monitors are remarkably intelligent (Varanus salvator intelligence). This intelligence makes them more trainable than many might expect, further enhancing the potential for interaction.
The intelligence and interactive nature of Asian Water Monitors facilitate a deeper bond with their keepers.

Male Asian Water Monitors can reach impressive lengths of five to eight feet, while females typically grow to four to six feet.
They also boast a longer lifespan than many other monitor species, living an average of 15 years in captivity, with some individuals reaching 20 years or more!
Adult Asian Water Monitors require enclosures measuring at least 8 feet by 6 feet by 8 feet. However, they can be started in smaller enclosures that are gradually upgraded as they grow.
Exploring Iguanas as Big Lizard Pets
Having explored the monitor lizard options for big lizard pets, let’s now turn our attention to iguanas. While sharing the “large lizard” designation, iguanas offer a different set of characteristics and care requirements.
Similar to monitors, certain fundamental needs apply to all iguanas kept as pets:
- Large, Arboreal Habitat: Iguanas are arboreal and require tall enclosures with ample vertical space for climbing and basking.
- Basking Lights: Multiple basking lights are essential to provide a temperature gradient and allow for thermoregulation.
- Vegetarian Diet: Iguanas are herbivores and require a diet consisting primarily of vegetation.
- Mineral Balance: Maintaining proper mineral ratios in their diet is crucial, particularly calcium and phosphorus, and varies depending on their life stage.
- Water Source for Soaking: A large water bowl is necessary not only for drinking but also for soaking, which aids in shedding and hydration.
Recommendation #1: Green Iguana – The Iconic, Yet Demanding, Big Lizard Pet
The Green Iguana (Iguana iguana) is arguably the most recognizable iguana and a familiar face in the large reptile pet trade. Their vibrant green coloration has contributed to their popularity as pets. However, this popularity is not always a positive attribute.
Opinions on Green Iguanas as pets are divided. Some consider them among the worst reptiles to keep compared to others, while others believe they are manageable if provided with proper habitat conditions and care.
This discrepancy in opinion stems partly from variations in Green Iguana personalities. Some individuals can be relatively docile, while others exhibit aggressive tendencies.
An aggressive Green Iguana can easily inflict serious injuries, potentially sending their caretaker to the emergency room, especially if they bite and employ predatory behaviors like the “death roll.” Loss of fingers has been reported in extreme cases.
Green Iguana temperament can fluctuate based on age, sex, and developmental stage. For instance, a juvenile male Green Iguana might initially be docile but become aggressive and permanently lose its friendly disposition as it matures.
Green Iguana habitats, like those of other big lizard pets, must be LARGE! They require ample space for movement and climbing, along with precise temperature and humidity levels.
Success in keeping Green Iguanas hinges on meticulous planning before acquiring one. Impulse purchases are highly discouraged.
🤓 Expert Tip: If you are seeking a reptile for a child, the Green Iguana, and indeed most big lizard pets on this list, are not suitable choices. Instead, opt for a beginner-friendly lizard that is easier to handle and care for.
Recommendation #2: Rhinoceros Iguana – A More Docile Big Lizard Pet Option
Rhinoceros Iguanas (Cyclura cornuta) typically range from two to four feet in length. Compared to Green Iguanas, their temperaments are generally considered more placid and predictable.
While they may exhibit a more skittish phase during adolescence, this usually subsides as they reach adulthood.
Rhinoceros Iguanas can live up to 20 years in captivity. This lifespan signifies a long-term commitment, but also means more years enjoying a potentially docile adult iguana after navigating the less predictable juvenile phase.
However, this 20-year lifespan underscores the significant commitment involved in owning a Rhinoceros Iguana.
Despite their generally calmer temperament, not all Rhinoceros Iguanas are inherently docile, nor are they suitable for all reptile keepers.
As with other big lizard pets, Rhinoceros Iguanas demand substantial space. Their care requirements, combined with their potential to cause injury, place them firmly in the “not for beginners” category.
However, a reptile keeper with moderate experience might consider a Rhinoceros Iguana after thorough research and preparation.
For a less demanding iguana option, consider the desert iguana. Its smaller size and more docile temperament make it a much lower-maintenance pet.

Honorable Mentions in the Big Lizard Pet World
Beyond monitors and iguanas, two other species deserve consideration when exploring big lizard pets.
The Ackie Monitor offers a manageable medium-sized option within the monitor family, while the Argentine Tegu provides a more gentle giant alternative.
Ackie Monitor – A Beginner-Friendly Monitor Big Lizard Pet (Relatively Speaking)
The Ackie Monitor (Varanus acanthurus) is not a truly giant lizard, reaching only about 28 inches in length.
However, it stands out as one of the easiest and most tractable monitor species to keep, often recommended as a “beginner monitor” for aspiring monitor lizard keepers.
If you are drawn to monitors but intimidated by the larger species, the Ackie Monitor is an excellent starting point, despite its moderate size compared to true giants.
Argentine Tegu – The Gentle Giant of Big Lizard Pets
The Argentine Tegu (Salvator merianae) is neither a monitor nor an iguana, belonging to the tegu family. This impressive lizard grows up to four feet long and is known for its wonderful, often playful, personality.
Argentine Tegus can live for up to 20 years and are powerful and athletic animals. Yet, despite their strength, bites are relatively uncommon, especially with consistent handling and proper care.
Argentine Tegus are omnivores, requiring a higher protein diet when young, transitioning to a more vegetation-heavy diet as they mature.
This intelligent species is trainable and can be harness-trained with patience and consistent effort, allowing for supervised outdoor exploration.

Wrapping Up Your Journey into Big Lizard Pets
Choosing a big lizard pet is a decision that should not be taken lightly. All giant lizard species are powerful animals demanding significant commitment, resources, and expertise. It’s wise to gain experience with smaller, less demanding lizards before considering a giant species.
When you are truly ready to commit the necessary space, budget, and decades of your life to caring for a giant lizard, the rewards can be immense.
If you choose to embark on this path, starting with the Argentine Tegu or the Asian Water Monitor is advisable. For a more gradual introduction to larger lizard care, the medium-sized Ackie Monitor is an excellent stepping stone.
