摘要

加利福尼亚黑虫（Lumbriculus variegatus）生活在水下，为了呼吸和稳定，它把尾巴锁在水面上。这种姿势所产生的向上的力鲜为人知。在这个结合实验和理论的研究中，我们可视化了黑虫和黑虫模拟物的半月板形状，由光滑和波纹环氧棒组成。我们应用先前的浮柱理论模型，预测了黑虫以及其他生物（如蚊子幼虫、水蛭和水生蜗牛）的向上力和安全系数。了解附着在水面上的生物向上的力量可能有助于理解界面附着的进化，并启发仿生机器人。

Flotation of aquatic worms and other hyponeuston.

The California blackworm, Lumbriculus variegatus, lives underwater and latches its tail to the water surface for respiration and stability. Little is known about the upward force generated by this posture. In this combined experimental and theoretical study, we visualize the menisci shape for blackworms and blackworm mimics, composed of smooth and corrugated epoxy rods. We apply previous theoretical models for floating cylinders to predict the upward force and safety factor of blackworms as well as other organisms such as mosquito larvae, leeches and aquatic snails. Understanding the upward forces of organisms that latch onto the water surface may help to understand the evolution of interfacial attachment and inspire biomimetic robots.

期刊介绍： Each Interface Focus themed issue is devoted to a particular subject at the interface of the physical and life sciences. Formed of high-quality articles, they aim to facilitate cross-disciplinary research across this traditional divide by acting as a forum accessible to all. Topics may be newly emerging areas of research or dynamic aspects of more established fields. Organisers of each Interface Focus are strongly encouraged to contextualise the journal within their chosen subject.
