Rhino Iguana

The Rhino Iguana (Cyclura cornuta) is native to Hispaniola and surrounding islands in the Caribbean. As one of the largest rock iguana species, these reptiles can reach impressive sizes and are highly respected among experienced reptile keepers. Their distinctive horns and rugged appearance make them one of the most recognizable iguana species in captivity.

Rhino Iguanas are intelligent, curious, and often develop strong recognition of their caretakers. While juveniles may be shy or defensive, many adults become calm and interactive with consistent socialization. They are often considered among the most personable large lizards in the reptile hobby.

Provide fresh food and water daily. Monitor temperatures, humidity, and UVB lighting regularly. Spot-clean waste as needed and perform routine enclosure maintenance. Rhino Iguanas benefit greatly from supervised exploration and environmental enrichment.

A proper Rhino Iguana diet should consist primarily of: Collard greens Mustard greens Dandelion greens Endive Escarole Hibiscus flowers Squash Bell peppers Occasional fruits as treats Avoid excessive fruit, iceberg lettuce, spinach in large quantities, and animal protein. Calcium supplementation should be provided regularly.

Rhino Iguanas require very large enclosures. Recommended setup includes: Minimum adult enclosure size of 8' x 4' x 6' Larger custom-built habitats preferred Multiple basking platforms Climbing structures Secure hiding areas Large water dish Strong UVB lighting Durable enclosure materials Outdoor enclosures can be beneficial in appropriate climates.

Ambient Temperature: 78–88°F Basking Area: 100–110°F Night Temperature: 72–78°F Humidity: 50–70% Proper UVB exposure is critical for calcium metabolism and overall health.

Annual wellness examinations with an experienced exotic veterinarian are highly recommended. Monitor for metabolic bone disease, obesity, respiratory infections, parasites, and mouth infections. Routine fecal testing can help identify internal parasites before they become problematic.

Rhino Iguanas can exceed 4 feet in length and live for decades. They require substantial space, specialized lighting, and a significant financial commitment. Prospective owners should be prepared for the long-term responsibility of caring for a large reptile and ensure local regulations permit ownership before purchasing.
