The first three larval stages of the lobster Homarus gammarus are pelagic swimming animals. A description is given of the exopodite apparatus of the thoracic appendages that provide lift and propulsive power in these stages. Setal arrangement and display provides greater surface area during power strokes. Musculature is peculiar to the exopodites and concerned with rotational movements of the appendage. Metachronal beating takes place with the segmental appendages moving in a variable sequence.
龙虾欧洲螯虾的前三个幼体阶段是浮游游泳动物。本文描述了胸附肢的外肢结构,这些结构在这些阶段提供升力和推进力。刚毛的排列和展示在动力冲程期间提供了更大的表面积。肌肉组织是外肢所特有的,与附肢的旋转运动有关。节段性附肢以可变顺序移动,进行顺序波动。
