How Iguanas Change Colors
Iguanas can shift their skin color by expanding or contracting pigment cells called chromatophores. This process is controlled by hormones and nerves, allowing rapid visual changes in response to environment and internal state.
Why Iguanas Change Color
Color change helps iguanas regulate body temperature, with darker shades absorbing more heat and lighter shades reflecting sunlight. It also plays a role in social signaling, territorial displays, and stress responses during encounters with rivals or predators.
Common Color Changes in Pet Iguanas
Pet iguanas may appear darker when cold, brighter during breeding season, or muted when stressed. Sudden or extreme color shifts can signal illness, poor nutrition, or inadequate lighting, so consistent monitoring is important for reptile health.
