Analysis of the motor component in feeding behaviour of the crayfish enabled to differentiate it into separate fragments with respect to the targets which are reached due to realization of each of these fragments. It is suggested that separate fragments are realized by some functional blocks which are activated from their own receptive zones by trigger mechanisms. With changing the coordinates of food stimulus the whole structure of the behaviour also changes due to the inclusion of additional fragments (locomotions, rearrangement of postures, activation of the claw extremities, etc.). Since this rearrangement favours the animal in reaching its final target, it may be considered as adaptive one.
对小龙虾摄食行为中运动成分的分析，能够根据因每个片段的实现而达成的目标，将其行为区分为不同的片段。研究表明，不同的片段由一些功能块实现，这些功能块通过触发机制从其各自的感受区被激活。随着食物刺激坐标的变化，行为的整体结构也会因纳入额外的片段（运动、姿势重新调整、螯肢激活等）而发生改变。由于这种重新调整有利于动物达成其最终目标，因此可将其视为一种适应性行为。
