How do lizards control their body temperature?
Lizards usually use the sun and shade to regulate their body temperature, a process known as thermoregulation. If real lizards achieve body temperatures different from that achieved by the random walking model, then they are walking non-randomly (deliberately) with respect to temperature.
Why do lizards lie in the sun?
Lizards and other cold-blooded critters bask in the sun to keep warm. But they also do it for the vitamin D, a new study finds.
