Abstract

Ten specimens ofBoiga irregularis were presented with clean or bloody tampons. The latter were used by women during menses. Trial duration was 60 sec, intertrial interval was 24 hr, and the dependent variable was rate of tongue flicking (a measure of chemosensory investigation). Bloody tampons elicited significantly more tongue flicking than did control tampons. An additional snake is shown attacking and ingesting a soiled tampon, confirming that chemosensory interest was associated with predatory behavior.

摘要

共展示了 10 条斜鳞蛇标本，它们接触的是干净的或沾有血的卫生棉条。后者是女性在经期使用的物品。实验持续 60 秒，两次实验之间间隔 24 小时，因变量是舌头舔舐的频率（一种化学感受探究的测量方法）。沾有血的卫生棉条比干净的卫生棉条引发了更多的舔舐行为。另一条蛇正在攻击并吞食一块脏的卫生棉条，这进一步证实了蛇对化学感受的兴趣与捕食行为有关。
