PERSISTENCE OF TRAILING BEHAVIOR: CUES INVOLVED IN POSTSTRIKE BEHAVIOR BY THE RATTLESNAKE (CROTALUS VIRIDIS OREGANUS)

PERSISTENCE OF TRAILING BEHAVIOR: CUES INVOLVED IN POSTSTRIKE BEHAVIOR BY THE RATTLESNAKE... PERSISTENCE OF TRAILING BEHAVIOR: CUES INVOLVED IN POSTSTRIKE BEHAVIOR BY THE RATTLESNAKE (CROTALUS VIRIDIS OREGANUS) by TAMARA L. SMITH 1) , KENNETH V. KARDONG 1,2) and PABLO A.

Victoria, Tamaulipas 87010, Mexico) (Acc. 8-II-2000) Summary Following the release of envenomated prey, a rattlesnake exhibits a series of poststrike behaviors, involving largely chemosensory cues that lead to recovery and swallowing of the dead prey. Unlike prestrike chemosensory activity that may help the snake place itself generally in the vicinity of prey, this poststrike trailing is more speciŽ c and selective. The rattlesnake discriminates the particular poststrike trail of the envenomated mouse from odor trails of other unstruck mice. But an envenomated prey may dash signiŽ cant distances over complicated terrain. Consequently, poststrike trailing by the rattlesnake may take hours during which it is exposed to its own predators. If the odor trail ages signiŽ cantly, losing its perceptibility, then poststrike trailing eventually becomes futile. To examine this, each rattlesnake was permitted to strike prey, but allowed to follow the placed scent trails http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Behaviour Brill

Abstract
