箭鱼（Toxotes）以其从悬垂的树叶中击落猎物的能力而闻名。然而，吐痰行为的生物力学相对未知。这项研究分析了产生压力所需的结构，这些压力涉及在水面以上1.20米处拍摄水滴。运动图像（300帧/秒）的结果，结合肌电图技术显示，吐是单相的。结合相关结构尺寸的三维数学模型的结果表明，舌头起着主导作用。嘴阀作为一个颤振阀，指导的轨迹的过程。该数学模型具有一般性，可用于鱼类或高等脊椎动物中所遇到的封闭运动学空间系统的其他研究。
The archer fish (Toxotes) is famous for its ability to shoot down prey from overhanging foliage. However, the biomechanics of the spitting act is relatively unknown. This study analyses the structures needed to generate the pressures involved in shooting water droplets up to 1.20 m above the water surface. The results of motion pictures (300 frames/s), combined with electromyographic techniques reveal that the spit is monophasic. The results of a three-dimensional mathematical model incorporating the relevant structural dimensions, show that the tongue plays a dominant role. The mouth valves act as a flutter valve, directing the course of the trajectory. The mathematical model is formulated generally and is applicable to other studies of closed kinematic spatial systems encountered in fishes or higher vertebrates.
