Appearance

The red-eyed crocodile skink has a slender, elongated body with a short tail, measuring around 20-25 cm in length. Its scales are granular and brown or black in color, providing camouflage in its natural habitat. However, what truly distinguishes this skink is its namesake feature: vivid red eyes that stand out amidst its darker body coloration. The skink's eyes are large and expressive, giving it an almost human-like appearance.

Habitat and Distribution

Red-eyed crocodile skinks are primarily found in rainforests, woodlands, and coastal areas of Australia and New Guinea. They favor habitats with ample vegetation and moisture, as they rely on humid environments to maintain their delicate skin.

Behavior and Diet

Red-eyed crocodile skinks are generally docile and shy creatures, preferring to avoid potential predators. They are nocturnal, becoming active at dusk and spending the day concealed beneath rocks, logs, or leaf litter. As omnivores, they feed on insects, small invertebrates, berries, and even the occasional small lizard or rodent.

Care and Husbandry

**

Enclosure

Providing an adequate enclosure is crucial for the well-being of red-eyed crocodile skinks. A terrarium measuring at least 20 gallons is recommended for a single individual, with additional space required for multiple skinks. The enclosure should include a secure hiding spot, a moist substrate such as cypress mulch, and a water dish.

**

Lighting

Red-eyed crocodile skinks require both UVB and UVA lighting to maintain their health and promote natural behaviors. UVB lighting helps regulate calcium absorption, while UVA lighting stimulates activity and appetite.

**

Temperature

The ideal temperature range for red-eyed crocodile skinks is between 75-80°F (24-27°C) during the day and 65-70°F (18-21°C) at night. It is important to provide a temperature gradient within the enclosure, allowing the skink to thermoregulate according to its needs.

**

Feeding

Red-eyed crocodile skinks should be fed a balanced diet consisting of crickets, mealworms, dubia roaches, and occasional gut-loaded insects. It is important to dust insects with calcium and vitamin D3 supplements to prevent nutritional deficiencies.

Potential Health Issues

Like all animals, red-eyed crocodile skinks can experience certain health issues. Common concerns include:

• Respiratory infections: Red-eyed crocodile skinks are prone to respiratory infections due to their humid habitat. Signs include difficulty breathing, wheezing, and nasal discharge.
• Skin infections: Improper humidity levels or lack of proper ventilation can lead to skin infections. Signs include red, irritated skin, and blisters.
• Gastrointestinal parasites: Red-eyed crocodile skinks may harbor internal parasites, which can cause symptoms such as weight loss, lethargy, and diarrhea.

Conclusion

The red-eyed crocodile skink is a fascinating and rewarding reptile for experienced reptile keepers. By providing appropriate care and meeting their specific requirements, these unique creatures can thrive in captivity, offering their owners endless hours of enjoyment and observation.
