Abstract
Shielding the parietal eye of horned lizards (Phrynosoma douglassi) led to a significant elevation in the upper voluntary temperature associated with shuttling, eye bulging, postural changes, panting, and cloacal discharge. Removal of the shield caused a lowering of the upper voluntary temperature to the level of the control group. A time lag was observed in both the elevation and lowering of body temperature, suggesting that the changes involved a hormone, possibly melatonin.
