如果小龙虾(P.clarkii)受到食物或威胁刺激，或两者兼而有之，它们的取食行为和甩尾躲避威胁的行为显示出灵活的互动模式。如果他们吃的是大块的、相对不能移动的食物，就会被阻止逃跑；如果吃的是小块食物，逃跑的可能性就会增加。如果在喂食比赛中发生逃逸，通常会释放大块食物，但不会释放小块食物。这些观察表明，负责协调无脊椎动物行为的神经回路可能并不像通常假设的那样简单。
If crayfish (P. clarkii) are presented with food or threat stimuli, or both, their feeding behavior and escape from threat by tail flips show flexible patterns of interaction. If they are engaged in eating large, relatively immovable pieces of food, escape is inhibited; if small pieces of food are being eaten, the probability of escape is enhanced. If escape occurs during a feeding bout, large pieces of food are usually released, but small ones are not. These obserations suggest that the neural circuitry responsible for coordination of behavior in invertebrates may not be as simple as usually assumed.
