The earless monitor lizard ( Lanthanotus borneensis ), a fascinating and relatively rare species, presents unique challenges and rewards for dedicated reptile keepers. This guide provides essential information for ensuring the well-being of these captivating creatures.

Habitat Setup: Mimicking Borneo

Creating a suitable enclosure is paramount for an earless monitor's health. These lizards are native to the rainforests of Borneo, so replicating that environment is crucial.

Enclosure Size and Type

A large enclosure is essential, ideally a custom-built terrarium or a large, secure aquarium. Minimum dimensions should be 4 feet long, 2 feet wide, and 2 feet high for a single adult, with larger enclosures preferred. Excellent ventilation is crucial to prevent fungal and respiratory infections.

Substrate and Furnishings

The substrate should be a moisture-retentive mix, such as a blend of peat moss, coco coir, and leaf litter. This provides appropriate humidity and allows for burrowing behavior. Include plenty of branches, cork bark, and artificial plants to create hiding places and climbing opportunities. A shallow water dish should always be available.

Temperature and Humidity

Maintaining the correct temperature and humidity is vital. A temperature gradient should be established, with a basking spot reaching 85-90°F (29-32°C) and cooler areas around 75-80°F (24-27°C). High humidity levels, between 70-80%, are essential. Regular misting may be necessary to maintain this humidity.

Diet: A Carnivorous Craving

Earless monitor lizards are primarily carnivorous, with a diet consisting of various invertebrates and small vertebrates.

Dietary Components

Their diet should consist of a balanced variety of insects (crickets, roaches, mealworms), earthworms, small frogs, and occasionally small lizards or mice (size appropriate to the lizard). Calcium and vitamin supplements should be dusted on prey items regularly.

Feeding Frequency

Adult earless monitors generally require feeding every 2-3 days, while juveniles may need to be fed more frequently. Always observe your lizard's body condition and adjust feeding accordingly. Obesity is a potential concern.

Handling and Health

Handling earless monitors should be minimized to reduce stress. However, regular visual inspection for signs of illness is essential.

Signs of Illness

Look out for lethargy, loss of appetite, skin changes, and respiratory distress. If any of these are observed, consult a veterinarian specializing in reptiles immediately.

Veterinary Care

Finding a reptile veterinarian experienced with monitor lizards is crucial for preventative care and treatment of any potential health issues. Regular veterinary checkups are recommended.

Conclusion

Keeping an earless monitor lizard is a significant commitment requiring dedication, research, and resources. By providing a meticulously created habitat, a balanced diet, and vigilant monitoring of their health, you can give your earless monitor the best possible chance at a long and fulfilling life. Remember, responsible ownership includes thorough research and a preparedness to meet the long-term needs of this fascinating reptile.
