Introduction: Why Lizards Bask in the Sun

Have you ever seen a lizard lying on a rock or a tree branch, seemingly doing nothing? Many people assume that lizards are lazy animals that soak up the sun all day long. However, basking in the sun is an essential activity for lizards. It is not a matter of laziness but a matter of survival. In this article, we will explore the reasons why lizards need to be in the sun.

Thermoregulation and Lizards

Lizards are ectothermic animals, which means that they cannot regulate their body temperature internally. Instead, their body temperature fluctuates with the ambient temperature of their surroundings. To maintain the optimal body temperature for their physiological functions, lizards need to move between warm and cool areas. Basking in the sun is one of the ways that lizards regulate their body temperature. By exposing themselves to sunlight, they absorb heat from the environment, which raises their body temperature. When they get too warm, they move to a cooler area to prevent overheating.
