The diverse ways and environments in which animals move are correlated with morphology¹, but morphology is not sufficient to predict how animals move because behavioral innovations can create new capacities. We document a new mode of snake locomotion — ‘lasso locomotion’ — that allows the brown treesnake (Boiga irregularis) to ascend much larger smooth cylinders than any previously known behavior. This lasso locomotion may facilitate exploiting resources that might otherwise be unobtainable and contribute to the success and impact of this highly invasive species.

套索运动扩展了蛇的攀爬曲目

动物移动的不同方式和环境与形态学¹相关，但形态学不足以预测动物如何移动，因为行为创新可以创造新的能力。我们记录了一种新的蛇运动模式——“套索运动”——它允许棕色树蛇（不规则蛇）上升到比任何以前已知的行为都大得多的光滑圆柱体。这种套索运动可能有助于开发资源，否则这些资源可能无法获得，并有助于这种高度入侵物种的成功和影响。
