From Wikipedia, the free encyclopedia

In reptiles, the nasal scale refers to the scale that encloses the nostril.<ref name="Mal03">Mallow D, Ludwig D, Nilson G. 2003. True Vipers: Natural History and Toxinology of Old World Vipers. Malabar, Florida: Krieger Publishing Company. 359 pp. ISBN 0-89464-877-2.</ref>

Sometimes this scale is paired (divided). In such cases, the anterior half is referred to as the prenasal and the posterior half is referred to as the postnasal.<ref name="W&W57">Wright AH, Wright AA. 1957. Handbook of Snakes.
