The Rhinoceros Iguana (Cyclura cornuta) is a fascinating species known for its distinctive horn-like structures on the snout, which give it an impressive appearance reminiscent of a rhinoceros. This large lizard can reach lengths of up to 54 inches (136 centimeters) and typically displays a color palette that ranges from steely gray to dark green or brown. Found predominantly on the island of Hispaniola and surrounding areas, the Rhinoceros Iguana thrives in arid habitats, favoring rocky terrains and scrub woodlands. Their adaptability is remarkable; as human activity and invasive species have encroached upon their natural coastal habitats, these iguanas have been known to migrate inland, demonstrating phenotypic plasticity to survive in different environments.

In addition to their impressive size and unique morphology, Rhinoceros Iguanas play a crucial ecological role as seed dispersers within their habitats. Their diet is primarily herbivorous, consisting of leaves, flowers, and fruits, but they are also opportunistic feeders and have been observed consuming small animals, insects, and carrion. This diverse diet contributes to their importance in maintaining the balance of their ecosystem. Interestingly, both male and female Rhinoceros Iguanas exhibit less sexual dimorphism than many other lizard species; both sexes possess well-developed dewlaps and horns, which they use in social interactions and competition, particularly among females competing for nesting sites. Their docile nature makes them popular in captivity, but they face numerous threats in the wild, including habitat loss and predation from invasive species, emphasizing the need for continued conservation efforts to ensure their survival.
