跨越许多长度尺度的生物体会产生特定的运动策略，这对它们的生存至关重要。在这里，我们详细介绍了一种非传统生物的运动，墨西哥跳豆，其中一个包裹在种子中的幼虫盲目地移动种子以寻找阴影。利用图像分析技术，我们定量地描述了这些物体作为活动粒子的运动。根据这些实验数据，我们建立了一个计算模拟，定量地捕捉这些豆子的运动。我们进一步评估了使用所观察到的扩散策略寻找阴影的有效性，表明随机行走是一种有利的生存策略。
Organisms across many lengthscales generate specific strategies for motion that are crucial to their survival. Here, we detail the motion of a nontraditional organism, the Mexican jumping bean, where a larva encapsulated within a seed blindly moves the seed in search of shade. Using image analysis techniques, we quantitatively describe the motion of these objects as active particles. From this experimental data, we build a computational simulation that quantitatively captures the motion of these beans. And we further evaluate the effectiveness of using the observed diffusive strategy to find shade, suggesting that the random walk is an advantageous strategy for survival.
