许多种类的水生无脊椎动物，包括甲壳类动物，通过摆动的多个紧密相连的附肢游泳。与同步划桨相比，这些附肢的协调、不同阶段的运动，即所谓的“超时划桨”，已被广泛用于提高游泳成绩。采用这种推进策略的无脊椎动物涵盖了广泛的身体大小和形状，但据报道，附肢间距(G)与附肢长度的比率(L)处于相对较窄的0.2%的范围内
Numerous species of aquatic invertebrates, including crustaceans, swim by oscillating multiple closely spaced appendages. The coordinated, out-of-phase motion of these appendages, known as "metachronal paddling," has been well-established to improve swimming performance relative to synchronous paddling. Invertebrates employing this propulsion strategy cover a wide range of body sizes and shapes, but the ratio of appendage spacing (G) to the appendage length (L) has been reported to lie in a comparatively narrow range of 0.2
