Abstract
Bushmasters (Lachesis muta) that were observed during feeding episodes occasionally released rodents after the predatory strike. For one such episode, we report the presence of a sustained, high rate of tongue-flicking that lasted 136 min. In this paper, we also present photographs showing skin folds that cover the snake’s pits and eyes when a rodent prey was being held following the predatory strike. We suggest that L. muta may occasionally exhibit strike-induced chemosensory searching and trail-following when large (but ingestible) prey are encountered.
