Stretched Out Iguana Legs?!

Green iguanas stretch out their legs while lying down for several reasons, primarily related to comfort and thermoregulation:

Thermoregulation: Green iguanas, as cold-blooded reptiles, depend on external heat sources to regulate their body temperature. Stretching out their legs increases the surface area of their body exposed to sunlight or a warm surface, helping them absorb more heat efficiently.

Relaxation: Stretching is a sign of relaxation and comfort. When iguanas feel safe in their environment, they stretch out their limbs to relax their muscles and rest more comfortably.

Circulation: Like many animals, stretching helps improve blood circulation. After periods of inactivity, stretching can enhance blood flow to their limbs and prepare them for movement.

Behavioral Habit: In the wild, iguanas often bask in the sun on branches or rocks. This stretched posture allows them to maximize contact with the surface, which is often warm.
