Turks and Caicos Reptile Checklist were consolidated for the first time in a comprehensive study. This region, characterized by small Caribbean islands scattered like dots, is home to 11 native terrestrial reptile species; eight of these are found nowhere else on Earth. This represents an evolutionary uniqueness that far exceeds the physical size of the islands.
The study, published in *ZooKeys* on August 27, 2026, by R. Graham Reynolds of the University of North Carolina Asheville, integrates literature up to 2026 with field data collected between 2006 and 2025. It is not merely a list of names but a ‘conservation baseline’ that encompasses distribution, habitat, natural history, specimen details, photographs, and genetic data.
30-Second Summary
- There are 11 native terrestrial reptile species in the Turks and Caicos Islands, eight of which are endemic to the region.
- The study integrates literature up to 2026 and field surveys conducted from 2006 to 2025.
- Seven of the 11 species fall into categories of conservation concern.
- The Turks Island skink was classified as Critically Endangered (CR), and the Turks and Caicos iguana as Endangered (EN).
- “Invasive mammals, habitat destruction, and road fatalities are the primary threats.
What happened?
A paper published in *ZooKeys* (Issue 1290) presents the first annotated checklist and species accounts for all native terrestrial reptiles of the Turks and Caicos Islands, an archipelago comprising over 200 islands and islets. Each account includes up-to-date taxonomy, type specimens, morphology, distribution, habitat, natural history, and IUCN status. The researchers included field photographs and reported Antillotyphlops platycephalus the first genetic sequence data and photographs of specimens collected in the Turks and Caicos.
Key Species Information
| Common Name (Descriptive Name) | English name | Scientific name | Classification | Distribution | Conservation Status |
|---|---|---|---|---|---|
| Turks Islands Skink | Turks Island skink | Spondylurus turksae | Order Squamata; Family Scincidae | Turks Bank; population on Cotton Cay is central | IUCN Critically Endangered (CR) |
| Turks and Caicos Iguana | Turks and Caicos rock iguana | Cyclura carinata | Order Squamata; Family Iguanidae | Turks and Caicos Islands | IUCN Endangered (EN) |
| Southern Bahamian Curly-tailed Lizard | Southern Bahamas curlytail | Leiocephalus psammodromus | Order Squamata; Family Leiocephalidae | Turks and Caicos Bank | Refer to the paper’s species accounts |
A baseline established through 20 years of field data
A strength of this study is that it goes beyond merely listing museum records. The researcher cross-referenced observational and specimen data collected from various islands between 2006 and 2025 with literature published up to 2026. This resulted in a baseline that tracks the presence of specific species across different islands, alongside the current composition of 11 species across eight families. Two of these species possess endemic subspecies, while one exists without endemic differentiation.
Taxonomic revisions are also included. The researcher proposed Leiocephalus psammodromus reclassifying the six subspecies of curly-tailed lizards—conventionally recognized—into L. p. psammodromus those of the Turks Bank and L. p. apocrinus those of the Caicos Bank.
Why is this important?
According to the paper and official announcements, 7 of the 11 species It is a species of conservation concern. In particular, Spondylurus turksae it is highly likely that the only remaining wild population is concentrated in a single protected area, Cotton Cay. Cyclura carinata It has been determined that the species has disappeared from approximately 90% of its historical range. Endemic species on small islands struggle to relocate to alternative habitats when faced with a combination of threats such as invasive mammals (e.g., cats and rats), development, and road mortality.
A checklist serves as the starting point for establishing conservation priorities. Accurate data on classification and distribution are essential to determine whether populations previously grouped under the same name constitute distinct conservation units, whether historical records remain valid today, and which islands should be prioritized for invasive species eradication and habitat restoration.
Points to avoid overinterpreting
This study is not a census that surveyed population numbers across all islands with equal intensity. The suggestion that the species might persist in only one location serves as a conservation warning based on confirmed data; it does not entirely rule out the possibility of remnant populations on small, unsurveyed islands. Furthermore, the proposal to downgrade the subspecies status could be revisited as more specimen and genomic data become available. The ecology of wild, endemic species should not be directly applied to captive environments.
Key takeaways for readers
- Eleven native terrestrial reptile species inhabit the Turks and Caicos Islands.
- Eight of these are endemic species found only in this archipelago.
- Twenty years of field data have established the first comprehensive baseline for island-by-island distribution.
- Seven species are of conservation concern, and the management of invasive species is a key challenge.
- Accurate classification could alter priorities for protected areas and restoration efforts.
