Why Choose a Black Throat Monitor?
Black Throat Monitors are ideal for those seeking a unique, intelligent, and awe-inspiring reptile. Their size and personality make them a standout pet, but they require a significant commitment in terms of space, time, and finances. They are not recommended for beginners but can be a fulfilling companion for seasoned reptile enthusiasts.
Handling and Temperament
Black Throat Monitors are not beginner-friendly reptiles. Their size aloneāreaching up to 7 feet in length and weighing around 60 poundsāmakes handling a physical challenge. Additionally, their intelligence and natural wariness of humans mean they require careful socialization from a young age to build trust.
Personality Variations
- Some Black Throat Monitors can become quite tame with consistent, gentle handling.
- Others may remain skittish or defensive, especially if not socialized properly.
- Their behavior as juveniles often reflects their adult temperament, so a calm baby is more likely to remain calm as it grows.
Handling Tips
- Start Early: Begin handling them when they are young to build trust and familiarity.
- Be Gentle: Avoid sudden movements or rough handling, as this can stress the lizard.
- Respect Their Space: Even a well-socialized monitor can become defensive if it feels threatened. Always approach with caution.
- Watch for Body Language: Monitors are excellent at communicating their mood. Puffing up, arching their back, or whipping their tail are signs of stress or aggression.
Biting and Defensive Behaviors
While Black Throat Monitors are not inherently aggressive, they have powerful jaws and sharp claws that can cause serious injury if they feel threatened. Bites are rare but can be severe, so handling should always be done with care and respect for the animalās boundaries.
Care and Maintenance
Caring for a Black Throat Monitor is a significant undertaking. These lizards require a lot of space, specific environmental conditions, and a varied diet to thrive.
Enclosure Setup
- Size: A custom-built enclosure is essential. For an adult, the enclosure should be at least 8 feet long, 4 feet wide, and 4 feet tall. Larger is always better.
- Climbing and Digging Space: Provide plenty of branches, rocks, and deep substrate (at least 12 inches) to allow for natural behaviors like climbing and burrowing.
- Substrate: Use a mix of coconut fiber, topsoil, and sand to create a substrate that holds burrows and maintains humidity.
- Hiding Spots: Include multiple hides to help the monitor feel secure.
Temperature and Humidity
- Basking Spot: Maintain a basking temperature of 120ā130Ā°F.
- Ambient Temperature: Keep the enclosure between 80ā85Ā°F during the day, with a slight drop at night.
- Humidity: Aim for 50ā70% humidity, which can be achieved with regular misting and a large water bowl.
Feeding
- Diet: Black Throat Monitors are carnivores and require a varied diet of whole prey, including rodents, birds, fish, and insects.
- Supplements: Dust prey items with calcium and multivitamin supplements to prevent nutritional deficiencies.
- Feeding Schedule: Juveniles should be fed daily, while adults can be fed every 2ā3 days.
Lighting
- Provide UVB lighting to support calcium metabolism and overall health. Mercury vapor bulbs are an excellent choice as they provide both heat and UVB.

Health and Durability
Black Throat Monitors are generally hardy when provided with proper care, but they are sensitive to environmental changes and improper diets.
Common Health Issues
- Metabolic Bone Disease (MBD): Caused by insufficient calcium or UVB exposure.
- Respiratory Infections: Often due to incorrect humidity or poor ventilation.
- Obesity: A risk if the lizard is overfed or lacks sufficient space to exercise.
Preventative Care
- Maintain proper temperature and humidity levels.
- Provide a balanced diet with appropriate supplements.
- Schedule regular check-ups with a reptile-savvy veterinarian.
With proper care, Black Throat Monitors can live 15ā20 years or more, making them a long-term commitment.
Availability and Cost
Black Throat Monitors are not as common as other reptiles, but they are available through specialized breeders and reptile expos.
Where to Buy
- Breeders: The best option, as they can provide healthy, well-socialized juveniles.
- Reptile Expos: A great place to meet breeders and see the lizards in person.
- Pet Stores: Rarely carry Black Throat Monitors, and captive-bred individuals are preferred over wild-caught ones.
Cost
- Initial Purchase: Juveniles typically cost between $500 to $1,500, depending on their size and source.
- Enclosure and Setup: Expect to spend several thousand dollars on a custom enclosure, lighting, and other supplies.
