However, until recently we have lacked high-resolution tools capable of revealing fine-scale patterns of behavior and habitat use, or providing empirical insight into swimming biomechanics of free-ranging sharks. Now a combination of high resolution, tri-axial accelerometer-magnetometer data loggers and miniature video loggers is uncovering previously unknown aspects of shark ecology. Recent deployments of these devices on a variety of coastal and deep-sea sharks in Hawaii has revealed complex, three-dimensional movements of these animals over a variety of habitats, provided a clearer understanding of shark swimming biomechanics and yielded a ‘sharks-eye’ view of interactions with other animals.
