  • The influence of prey-scent stimuli on predatory behavior of the North American copperhead Agkistrodon contortrix (Serpentes: Viperidae).
    Eli Greenbaum // Behavioral Ecology; Number 2 March, 2004, Vol. 15 Issue 2, p345 

    Viperid snakes strike, envenomate, and release mammalian prey to prevent being harmed by the prey; snakes must then track prey in the process of strike-induced chemosensory searching. Because rattlesnakes prefer to track and consume envenomated prey, it would seem that the scent of envenomated...
