Temperature-Frequency Relationship of the Rattlesnake Rattle
Preview not available

Abstract

The rattling frequency of the rattlesnake, Crotalus atrox, does not appear to be linear throughout a body temperature range of 3-40° C, although it does appear to be linear between 16 and 32 C. At the higher temperature (above 34 C) rattling becomes spasmodic because the antagonistic muscles on either side of the tail are contracting at the same time.
