• Coloration: Dark brown or black body with red eyes
• Scales: Keeled scales that resemble crocodile armor
• Teeth: Small, pointed teeth for hunting small prey
• Jaws: Powerful jaws for capturing and consuming insects

Natural Habitat and Behavior

Red-Eyed Crocodile Skinks are primarily found in the tropical rainforests of New Guinea and nearby islands. They prefer humid and densely vegetated environments, often hiding under fallen leaves, logs, or dense foliage. These skinks are nocturnal, emerging at night to hunt for their favorite prey, which includes insects, small invertebrates, and occasionally, small vertebrates.

In the wild, Red-Eyed Crocodile Skinks exhibit fascinating behaviors. They are known for their vocalizations, producing a variety of sounds, including hisses and grunts, to communicate with potential mates or warn off predators. Additionally, these skinks have a unique defense mechanism; when threatened, they can produce a loud, hissing sound by forcing air through their specialized nasal passages, startle potential predators, and provide an additional layer of protection.

Care and Housing

Providing proper care and housing is crucial for the well-being of Red-Eyed Crocodile Skinks in captivity. Here are some essential guidelines to ensure their health and happiness:

Enclosure Setup

• Size: A minimum enclosure size of 20 gallons is recommended for a single skink. Provide ample hiding spots and climbing structures to mimic their natural habitat.
• Substrate: Use a substrate that retains moisture, such as coconut coir or a mixture of peat moss and soil. This helps maintain humidity levels.
• Temperature: Maintain a temperature gradient within the enclosure, with a basking spot of around 85°F (29°C) and a cooler side around 75°F (24°C). Use a heat lamp or heat mat to create the basking area.
• Humidity: Red-Eyed Crocodile Skinks thrive in high humidity. Aim for a humidity level of 70-80% by misting the enclosure regularly and providing a shallow water dish.
• Lighting: Provide a UVB light source to promote proper calcium metabolism. Ensure the light is positioned correctly to avoid overheating.

Diet and Feeding

• Insects: Offer a variety of live insects, such as crickets, mealworms, and waxworms. Dust the insects with a calcium and vitamin D3 supplement to ensure proper nutrition.
• Feeding Schedule: Feed adult skinks every 2-3 days, offering a balanced diet of insects and occasional small vertebrates (e.g., pinky mice). Juveniles may require more frequent feedings.
• Hydration: Always provide a clean water dish for drinking and soaking. Mist the enclosure regularly to ensure adequate hydration.

Handling and Temperament

Red-Eyed Crocodile Skinks are generally docile and can become tame with regular, gentle handling. However, it's important to approach them slowly and avoid sudden movements to prevent stress. Handle your skink with care, supporting its body and avoiding excessive squeezing or constriction.

Breeding and Reproduction

Breeding Red-Eyed Crocodile Skinks in captivity can be challenging but rewarding. Here are some key considerations for successful breeding:

• Mating Behavior: Males may exhibit courtship behaviors, such as head-bobbing and vocalizations, to attract females. Ensure a suitable ratio of males to females in the enclosure.
• Nest Setup: Provide a nesting area with a substrate that allows the female to dig and lay her eggs. Maintain appropriate humidity and temperature levels during the breeding season.
• Incubation: Once the eggs are laid, they can be incubated in a separate container with a suitable substrate and stable temperature and humidity levels. Incubation times can vary, so patience is key.

Common Health Concerns

Like any reptile, Red-Eyed Crocodile Skinks are susceptible to certain health issues. Here are some common concerns to watch out for:

• Metabolic Bone Disease (MBD): Ensure proper calcium and vitamin D3 supplementation to prevent MBD. Provide a balanced diet and regular access to UVB lighting.
• Respiratory Infections: Maintain optimal humidity levels to prevent respiratory issues. Signs of respiratory infection include wheezing, nasal discharge, or difficulty breathing.
• Parasites: Regularly check your skink for external parasites, such as mites or ticks. If detected, consult a reptile veterinarian for appropriate treatment.

Conclusion

The Red-Eyed Crocodile Skink is a captivating and unique species that can make a fascinating addition to your reptile collection. With their distinctive appearance, intriguing behavior, and relatively docile temperament, they offer a rewarding experience for dedicated reptile enthusiasts. By providing proper care, including a suitable enclosure, a balanced diet, and regular veterinary check-ups, you can ensure the health and happiness of your Red-Eyed Crocodile Skink companion.
