Since Eastern Water Dragons are ectotherms, what dictates the primary focus of their daily routine in the mornings?

Basking on sun-exposed spots to absorb solar energy for optimal body temperature

As cold-blooded organisms, or ectotherms, the activity levels and metabolic functions of the Eastern Water Dragon are directly dependent on external heat sources, primarily the sun. Therefore, the morning routine is dedicated to thermoregulation. The dragon must carefully position itself on favored sunning locations—such as rocks or branches—to absorb solar energy. This process is essential to elevate its internal body temperature to the optimal range required for effective digestion and general movement throughout the rest of the day. Once this temperature goal is reached, or if disturbances occur, they shift their focus toward feeding or alertness.
