History & Origins
Lesser Antillean iguanas survive on handful of Caribbean islands, Critically Endangered from habitat loss and hybridisation with invasive Iguana iguana. CITES Appendix I prohibits commercial international trade. Any pet market offering 'Antillean iguanas' should be reported — conservation depends on genetically pure wild populations.
Lesser Antillean Iguana Fun Facts
- Hybridisation with green iguanas threatens genetic extinction of pure delicatissima.
- Critically Endangered on IUCN Red List — wild counts in low thousands.
- Endemic to Lesser Antilles — not the same species as common green iguana.
- CITES Appendix I listing prohibits commercial pet trade internationally.
Lesser Antillean 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.
Hybridisation with green iguanas (wild)
Introduced green iguanas breed with delicatissima, erasing pure genetics.
Care: Support island eradication programmes for invasive green iguanas.
Habitat loss (wild)
Development destroys coastal forest on limited island ranges.
Care: Fund protected area management in the Lesser Antilles.
Cannot be kept responsibly in homes
Legal protection and conservation status prohibit pet keeping.
Care: Redirect interest to conservation donations, 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.
