甲壳类动物利用气味和流体机械线索从环境中提取信息。这些线索使动物能够找到资源，适应水流，或逃避捕食者。由于流体环境的性质影响相关信号的传输和结构，因此通过同时考虑化学和机械感觉行为的流体动力学背景，将有助于更好地理解感觉和行为机制。甲壳类动物占据水生栖息地，其中流动范围从几乎完全层流到几乎完全湍流。流体动力学性质的相当大的范围反映在这些流动中夹带的信号的复杂性的同样极端的变化。环境噪声和随机变化在越来越多的能量，湍流条件下增加。在湍流环境中定向的动物的感觉和行为机制表明，它们在进化过程中受到流动特性的影响。在这里，感觉系统被调整为在嘈杂的背景下提取快速波动的信号。它们有时具有复杂的噪声过滤机制，能够检测相当粗糙的信号特征类型，以提高信噪比。相比之下，层流中携带的信号结构更简单、更可预测，可以实现更准确的定位和识别，并使动物摆脱支持复杂噪声过滤电路的负担。未来的比较研究的感觉生理和动物的行为与他们的流动环境的承诺，以增加我们的理解方向的化学和机械感知。
Crustaceans use odor and fluid mechanical cues to extract information from their environment. These cues enable animals to find resources, orient to water currents, or escape predators. Because the properties of the fluid environment affect the transmission and structure of relevant signals, a better understanding of sensory and behavioral mechanisms will be aided by considering, at the same time, the hydrodynamic context of chemo- and mechanosensory behaviors. Crustaceans occupy aquatic habitats where flows range from almost completely laminar to nearly fully turbulent. The considerable scope of hydrodynamic properties is mirrored by equally extreme variations in the complexity of the signals entrained in these flows. Ambient noise and stochastic variation increase in increasingly energetic, turbulent conditions. The sensory and behavioral mechanisms of animals that orient in turbulent environments suggest that they have, in the course of evolution, been shaped by the flow properties. Here, sensory systems are geared to extract rapidly fluctuating signals against a noisy background. They sometimes have elaborate noise filtering mechanisms that enable the detection of rather coarse types of signal features to improve the signal-to-noise ratio. In contrast, the simpler and more predictable structure of signals carried in laminar flows may allow more accurate orientation and discrimination to occur, and free animals from the burden of supporting complex noise-filtering circuitry. Future comparative investigations of sensory physiology and behavior of animals in relation to their flow environment promise to increase our understanding of orientation by means of chemo- and mechanoperception.
