Do Iguanas Change Color?
Iguanas can change color, but the shift is usually subtle and slower than in chameleons. Their skin contains pigment cells that respond to mood, temperature, health, and environment.
Why Do Iguanas Change Color?
Color changes often signal thermoregulation, stress, or social behavior. Darkening helps absorb heat, while lighter shades may reflect excess warmth or show submission during encounters with other iguanas.
When Color Change Signals a Problem
Sudden or extreme fading, darkening, or patchy discoloration can indicate illness, parasites, or poor husbandry. If color change is paired with lethargy, loss of appetite, or abnormal shedding, consult a reptile veterinarian promptly.
