Teiids are classic examples of actively foraging lizards. Teiids generally live in burrows they excavate themselves or that are made by other animals. A typical macroteiid day begins with the lizard basking in direct sun to raise its body temperature. Whiptails, especially Cnemidophorus and Ameiva, prefer relatively high body temperatures for activity, commonly measured in the field at 98.6°F-140°F (37°C-40°C). Once activity temperatures are achieved, a macroteiid embarks on long foraging or mate-seeking expeditions within its home range. Teiids maintain high body temperature while active by shuttling between sun and shade.
