Argentine Black and White Tegu

Black and White Tegu (Salvator merianae)

Overview

Black and White Tegus, also known as Argentine Tegus, are large, intelligent lizards native to South America. Renowned for their impressive size, striking appearance, and dog-like demeanor, these tegus make fascinating pets for experienced reptile enthusiasts. They are known for their intelligence and ability to form strong bonds with their keepers when properly socialized.

Physical Characteristics

• Size: Adult Black and White Tegus can reach 3-5 feet in length, with males typically larger than females.
• Lifespan: With proper care, they can live for 15-20 years.
• Appearance: These tegus have a distinctive black and white coloration, with banding patterns across their body and tail. They have a robust, muscular build and a long, powerful tail.

Housing

• Enclosure: Due to their size and activity level, Black and White Tegus require a spacious enclosure. An adult should have an enclosure that is at least 8 x 4 x 4 feet, though larger is always better.
• Substrate: Use substrates that support their burrowing behavior, such as cypress mulch, topsoil, or a sand-soil mix. These substrates should be deep enough to allow for digging and burrowing.
• Hides and Enrichment: Provide multiple hiding spots, climbing structures, and digging areas. Include large rocks, logs, and sturdy branches. Enrichment items like large, hollow logs or PVC pipes can help stimulate their natural behaviors.

Temperature and Humidity

• Temperature: Maintain a temperature gradient with a basking spot of 95-105°F and an ambient temperature of 80-85°F during the day. Night temperatures can drop to 70-75°F.
• Heating: Use basking lamps and ceramic heat emitters to achieve the desired temperature gradient. Ensure the basking area is large enough for the tegu's entire body to be heated.
• Humidity: Keep humidity levels between 60-80%. Provide a large water dish for soaking and mist the enclosure as needed to maintain proper humidity.

Lighting

• UVB Lighting: Black and White Tegus require UVB lighting to synthesize vitamin D3 and absorb calcium. Provide UVB lighting for 10-12 hours a day.
• Light Cycle: Maintain a regular 12-hour light/dark cycle to simulate natural conditions.
• Lighting Options: Use fluorescent UVB bulbs or mercury vapor bulbs to provide both heat and UVB light.

Feeding

• Diet: Black and White Tegus are omnivorous and require a varied diet of protein, fruits, and vegetables.
• Protein: Offer a variety of protein sources such as insects (crickets, mealworms), lean meats, eggs, and appropriately sized rodents. Dust insects with calcium and vitamin supplements.
• Fruits and Vegetables: Provide a variety of fruits (berries, melons) and vegetables (squash, leafy greens). Fruits should be offered in moderation due to their sugar content.
• Feeding Frequency: Juveniles should be fed daily, while adults can be fed 2-3 times a week. Adjust feeding frequency based on the individual’s growth and activity level.

Handling and Temperament

• Handling: Black and White Tegus can become very tame and even affectionate with regular, gentle handling. Start with short handling sessions and gradually increase the duration as the tegu becomes more comfortable. Always support their body fully to prevent stress or injury.
• Behavior: They are intelligent and curious, often exploring their environment and interacting with their keepers. Tegus can recognize their keepers and may seek attention and interaction.

Health and Veterinary Care

• Common Issues: Monitor for respiratory infections, metabolic bone disease, and parasites. Ensure proper UVB lighting, humidity, and a balanced diet to prevent health issues.
• Veterinary Care: Regular check-ups with a reptile veterinarian are essential to monitor their health and address any issues promptly.

Conclusion

Black and White Tegus are a remarkable and rewarding species that can make excellent pets for experienced reptile keepers. Their intelligence, engaging behaviors, and potential for strong bonds with their keepers make them a captivating addition to any reptile collection. With the right environment and care, Black and White Tegus can thrive and provide years of enjoyment to their keepers.
