尽管鲸鱼体型巨大，但它们以贪婪的捕食者为生。为了捕捉更小、更易捕获的猎物，它们发展了几种独特的运动策略，需要高能量输入、高机械功率输出和惊人的敏捷度。为了更好地了解身体大小如何影响最大规模的机动性，我们使用生物日志数据，航空摄影测量和高通量方法来量化七种自由游泳的须鲸的机动性能。我们发现，随着身体尺寸的增加，绝对机动性能下降：较大的鲸鱼使用较低的加速度和执行较慢的俯仰变化，滚动和转弯比较小的物种。我们还发现，须鲸表现出积极的异速生长的机动性能：相对于他们的身体大小，较大的鲸鱼使用更高的加速度，并执行更快的音高变化，滚动和某些类型的转弯比较小的物种。然而，并不是所有的动作都以同样的方式受到身体大小的影响，我们发现较大的鲸鱼通过使用它们可以更有效地执行的转弯来调整其敏捷性下降。操纵性能的正异速生长表明，大型鲸鱼已经通过进化更有效的控制表面和优先选择发挥其优势的操纵来补偿其增加的身体尺寸。 在大型鲸鱼物种中，机动性能随着体型的增大而降低，但大型鲸鱼的机动性能比预期的要好。
Despite their enormous size, whales make their living as voracious predators. To catch their much smaller, more maneuverable prey, they have developed several unique locomotor strategies that require high energetic input, high mechanical power output and a surprising degree of agility. To better understand how body size affects maneuverability at the largest scale, we used bio-logging data, aerial photogrammetry and a high-throughput approach to quantify the maneuvering performance of seven species of free-swimming baleen whale. We found that as body size increases, absolute maneuvering performance decreases: larger whales use lower accelerations and perform slower pitch-changes, rolls and turns than smaller species. We also found that baleen whales exhibit positive allometry of maneuvering performance: relative to their body size, larger whales use higher accelerations, and perform faster pitch-changes, rolls and certain types of turns than smaller species. However, not all maneuvers were impacted by body size in the same way, and we found that larger whales behaviorally adjust for their decreased agility by using turns that they can perform more effectively. The positive allometry of maneuvering performance suggests that large whales have compensated for their increased body size by evolving more effective control surfaces and by preferentially selecting maneuvers that play to their strengths. Maneuvering performance decreases with body size in large whale species, but larger whales maneuver better than expected.
