摘要在摄食过程中，鱼类需要下巴、身体和鳍的复杂协调运动，才能成功地执行攻击或咬合，然后离开捕食地点。与运动系统相结合，感觉形式指导协调的摄食行为，视觉在许多鱼类中扮演着重要的角色。虽然经常分开研究，但在鱼类饲养过程中，运动、摄食和视觉系统以前从未被一起检查过。为了探索摄食的协调性，我们研究了两种草食性鹦鹉的摄食行为的运动学，这两种鹦鹉表现出不同的单咬和重复咬策略。关于胸鳍运动和身体位置的运动学数据显示，这些物种在接近和攻击后运动的策略上存在明显差异。Sparisoma和Scarus在颌骨突出的程度、达到最大颌骨突出的时间、颅骨抬高和进食顺序中的事件顺序方面存在显著差异。眼球运动数据显示，这两种物种都会将瞳孔向前和向下指向颌骨接触处，直到咬合前100毫秒，此时视野会横向旋转。运动学变量的组合显示了接近食物(距离、速度、眼睛运动)、猎物捕捉(眼睛运动、下巴运动、鳍运动)和捕获后机动(鳍运动、距离)的重复同步模式(开始和持续时间)。对多功能系统的运动学分析揭示了在获取食物的过程中探测和接近猎物以及执行颌骨快速打开和关闭的协调机制。比较不同鱼种之间的摄食、游动和感觉系统的协调可以阐明珊瑚礁鱼类中涉及草食的不同协调策略。
SUMMARY Fishes require complex coordinated motions of the jaws, body and fins during feeding in order to successfully execute the strike or bite and then move away from the predation site. In conjunction with locomotor systems, sensory modalities guide coordinated feeding behavior, with vision playing an important role in many fishes. Although often studied separately, the locomotor, feeding and visual systems have not previously been examined together during fish feeding. To explore feeding coordination, we examined the kinematics of feeding behavior in two species of herbivorous parrotfish, Sparisoma radians and Scarus quoyi, which exhibit different single bite and repetitive bite strategies. Kinematic data on pectoral fin movements and body position show distinctive differences in strategies for the approach and post-strike motion between these species. Sparisoma and Scarus exhibited significant differences in the magnitude of jaw protrusion, time to maximum jaw protrusion, cranial elevation, and order of events in the feeding sequence. Oculomotor data show that both species orient the pupil forward and downward directed at the site of jaw contact until 100 ms before the bite, at which point the visual field is rotated laterally. Combinations of kinematic variables show repeated patterns of synchrony (onset and duration) for the approach to the food (distance, velocity, eye movement), prey capture (eye movement, jaw movement, fin movement) and post-capture maneuvering (fin movement, distance). Kinematic analyses of multiple functional systems reveal coordination mechanisms for detecting and approaching prey and executing the rapid opening and closing of the jaws during acquisition of food. Comparison of the coordination of feeding, swimming and sensory systems among fish species can elucidate alternative coordination strategies involved in herbivory in coral reef fishes.
