Brown tree snakes (Boiga irregularis) from Guam were exposed to mammalian (Rattus norvegicus) blood on cotton-tipped applicators. Water and other control substances were similarly presented. All trials lasted 60 s, and the dependent variable was the number of tongue flicks emitted by the snake during the trial. In five experiments, B. irregularis responded with greater numbers of tongue flicks to blood than to control substances. This is the first study to reveal an ophidian response to internal chemicals of potential prey organisms.
来自关岛的棕树蛇（Boiga irregularis）被暴露于用棉签蘸取的哺乳动物（褐家鼠）血液中。水和其他对照物质也以类似方式呈现。所有试验持续60秒，因变量是试验期间蛇发出的吐舌次数。在五项实验中，棕树蛇对血液的吐舌反应次数多于对照物质。这是首次揭示蛇类对潜在猎物生物体内化学物质产生反应的研究。
