Brown treesnakes (Boiga irregularis) responded with more tongue flicks to blood (from rabbits, rats, and mice) than to water. When rat blood was centrifuged at 3,500 rpm for 5 min, separating serum from cellular residue, snakes responded strongly to serum but not to cellular residue.
棕树蛇(Boiga irregularis)对血液(来自兔子、大鼠和小鼠)的吐舌反应比对水的吐舌反应更多。当将大鼠血液以3500转/分钟的速度离心5分钟,使血清与细胞残渣分离时,蛇对血清反应强烈,但对细胞残渣没有反应。
