三种基本类型的流体动力学和声学感受器可以区分在小龙虾：专门的感觉毛的身体表面，机械感受器的触角鞭毛的变形，和平衡囊。由于甲壳类动物没有充满空气的空腔，因此不太可能接收到声音的压力分量。不同受体系统的阈值曲线在低于150 Hz的频率下显示出最高的灵敏度，这与生物流体动力学事件的速度谱中低频的主导地位是一致的。
Three basic types of hydrodynamic and acoustic receptors can be distinguished in crayfish: specialized sensory hairs on the body surface, mechanoreceptors sensing the deformation of the antennal flagella, and statocysts. Since crustaceans are not equipped with air filled cavities, reception of the pressure component of sound is unlikely. Threshold curves of the different receptor systems show highest sensitivity at frequencies below 150 Hz, which is in accordance with the dominance of low frequencies in the velocity spectrum of biotic hydrodynamic events.
