Visual stimuli alerted rattlesnakes to the presence of potential prey and gave rise to elevated RTF which subsequently allowed these predators to utilize chemical cues that happened to be available.

As in several previous studies, chemosensory searching subserved by the vomeronasal system was activated consequent to the delivery of a successful predatory strike inirie rattlesnakes, but this effect was not observed when the snakes were disturbed just prior to being exposed to mice.

The present study shows strike-induced chemosensory searching to occur in species of rattlesnakes not previously investigated and in two species of Agkistrodon, and suggests that SICS in some viperids may have arisen through paedomorphic evolution.

Rattlesnakes (Crotalus enyo) exhibited higher rates of tongue flicking after striking and envenomating a mouse than after seeing, smelling, or detecting the warmth of a mouse, which suggests that predatory behavior in C. enyo is a closed response chain such that release of the first element strongly predisposes the snake to engage in the next element (chemosensory searching).

These distances give an indication of the extent of the trailing task that confronts a prairie rattlesnake under natural conditions and suggest laboratory studies of trailing behavior in rattle-snakes should use trails of at least 180-200 cm if results are to have ecological validity.

Effects of prey size on poststrike behavior in rattlesnakes (Crotalus durissus, C. enyo, and C. viridis)

Rattlesnakes of three taxa struck and released large rodent prey but held smaller rodents in their jaws after striking, consistent with the fact that large rodents are more dangerous to rattlesnake than are small rodents.

Duration of strike‐induced chemosensory searching in long‐term captive rattlesnakes at national zoo, audubon zoo, and San Diego Zoo

The duration of chemosensory searching in these snakes indicates that this important aspect of the predatory repertoire had not been degraded as a consequence of long-term captive husbandry.
