Iguana Species · Hispaniola (Haiti & Dominican Republic)
Rhinoceros Iguana
Horned snout and armoured appearance — endangered rock iguana, not a pet.
By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated
In brief
The Rhinoceros iguana (Cyclura cornuta) bears horn-like snout projections on Hispaniola — endangered rock iguana hunted and habitat-lost. Its defining trait is CITES Appendix I zoo conservation priority, not private pet ownership despite armoured dinosaur appearance.

History & Origins
Rhinoceros iguanas endemic to Haiti and Dominican Republic declined from deforestation, hunting for bushmeat and pet trade. Captive breeding exists in zoos for population management. Private keeping fails welfare and legal tests — Cyclura cornuta is not a domesticated species.
Rhinoceros Iguana Fun Facts
- Snout horns more pronounced in males — species name cornuta references horns.
- Endemic to Hispaniola — shared island with Haiti and Dominican Republic.
- Can live 50+ years in protected wild habitat.
- Zoo breeding programmes maintain genetic insurance for wild populations.
Rhinoceros Iguana Common Health Issues
Conditions seen more often in this breed, and how owners and vets help manage them. This is general guidance, not veterinary advice — always speak to your vet.
Habitat loss (wild)
Charcoal production and agriculture destroy xeric forest on Hispaniola.
Care: Support reforestation and protected area enforcement.
Hunting (wild)
Bushmeat and illegal pet collection remove breeding adults.
Care: Fund anti-poaching and community livelihood alternatives.
Cannot be kept responsibly in homes
Enclosure scale and Endangered status prohibit private keeping.
Care: Engage with zoo conservation, not ownership.
Most iguanas are not beginner pets
Green iguanas grow to two metres and live twenty years — most owners are unprepared. Released pets become invasive. Consider adoption only if you can meet specialist reptile welfare standards.
