Grenadines Horned Iguana
Iguana iguana insularis
Also classified by some researchers as Iguana insularis
The Grenadines horned iguana is a distinctive island form of green iguana native to the southern Lesser Antilles in the eastern Caribbean. Its natural range includes islands in the Grenadines and Grenada. The related Saint Lucia form is often classified as a separate subspecies, Iguana iguana sanctaluciae. Zootaxa
This iguana is known for the small horn-like scales on its snout. Adults of the Grenadines form are often pale gray, cream, or nearly white, with a lighter appearance than many familiar mainland green iguanas. Its island range and distinctive appearance make it an especially unusual member of the iguana family.
Like other green iguanas, it is primarily herbivorous, feeding on leaves, shoots, flowers, and fruit. Adult size has not been well documented specifically for this island form; green iguanas generally grow to around 4–6 feet from snout to tail tip, with the tail making up much of that length.

The Grenadines horned iguana is considered rare in the reptile world because it comes from a limited island range and faces conservation pressures. Researchers have documented hybridization with introduced iguanas in parts of the region, which can threaten the genetic integrity of native populations. PMC
Taxonomy note: The scientific name is treated differently by different authorities. We use Iguana iguana insularis here, while acknowledging that some recent research uses Iguana insularis as the species name.
