Iguana GuideIsland identity
Blue iguanas are associated with the dry, rocky landscapes of Grand Cayman. Island endemism makes their ecology and conservation inseparable from place.
Color and identification
Adult coloration can become strongly blue-gray, particularly in mature animals. Color alone should not be used as a universal identification shortcut across every iguana, because lighting, age and species differences matter.
Why island iguanas are important
Restricted island distributions make many iguana populations unusually vulnerable to habitat change, introduced predators and other human-driven pressures. Species pages on Iguana Guide therefore connect identification with ecology and conservation context.
Keep exploring
Iguana facts become more useful when anatomy, behavior, species and habitat are connected instead of treated as isolated trivia.

This reference page is intentionally conservative and will receive species-specific primary-source expansion before deeper factual claims are added.
