The anatomy of large cetaceans has been well documented, mostly through dissection of dead specimens. However, the difficulty of studying the world's largest animals in their natural environment means the functions of anatomical structures must be inferred. Recently, non-invasive tracking devices have been developed that measure body position and orientation, thereby enabling the detailed reconstruction of underwater trajectories. The addition of cameras to the whale-borne tags allows the sensor data to be matched with real-time observations of how whales use their morphological structures, such as flukes, flippers, feeding apparatuses, and blowholes for the physiological functions of locomotion, feeding, and breathing. Here, we describe a new tag design with integrated video and inertial sensors and how it can be used to provide insights to the function of whale anatomy. This technology has the potential to facilitate a wide range of discoveries and comparative studies, but many challenges remain to increase the resolution and applicability of the data.

大型鲸类的解剖结构已有详尽记录，大多是通过对死亡标本的解剖。然而，在自然环境中研究世界上最大的动物存在困难，这意味着解剖结构的功能必须通过推断得出。最近，已开发出非侵入性追踪设备，可测量身体位置和方向，从而能够详细重建水下轨迹。在安装于鲸鱼身上的标签上添加摄像头，能使传感器数据与鲸鱼如何利用其形态结构（如尾叶、鳍肢、进食器官和喷气孔）进行运动、进食和呼吸等生理功能的实时观测相匹配。在此，我们描述一种集成了视频和惯性传感器的新型标签设计，以及如何利用它来深入了解鲸鱼解剖结构的功能。这项技术有潜力推动广泛的发现和比较研究，但要提高数据的分辨率和适用性仍存在许多挑战。《解剖学记录》，300:1935 - 1941，2017年。© 2017威利期刊公司。
