水生动物在它们的逃跑或攻击演习中所采用的流体力学，我们称之为生存流体力学，是迷人的，因为动物的记录表现确实令人印象深刻。这样的性能迫使我们提出一些基本的流动机制，尚未在工程车辆中使用的问题。一个密切相关的问题是动物感知它们周围的流速和压力场的能力，以便在视觉或其他感知有限或没有用处的环境中检测和区分威胁。我们审查工作的动物流量传感和驱动的灵感来源，并作为一种方式来制定一些基本的问题，并调查流动机制，使动物能够执行这些显着的演习。我们还描述了一些有趣的驱动和传感机制。
The fluid mechanics employed by aquatic animals in their escape or attack maneuvers, what we call survival hydrodynamics, are fascinating because the recorded performance in animals is truly impressive. Such performance forces us to pose some basic questions on the underlying flow mechanisms that are not yet in use in engineered vehicles. A closely related issue is the ability of animals to sense the flow velocity and pressure field around them in order to detect and discriminate threats in environments where vision or other sensing is of limited or no use. We review work on animal flow sensing and actuation as a source of inspiration and as a way to formulate a number of basic problems and investigate the flow mechanisms that enable animals to perform these remarkable maneuvers. We also describe some intriguing mechanisms of actuation and sensing.
