Little is known about the hunting behavior of marine mammals, particularly in the inhospitable depths of the Antarctic. To shed light on the subject, Davis et al. (p. 993) have developed a near-infrared-based video observation system. Attached to the backs of Weddell seals, the system records video images of the seal's head and immediate environment while data loggers record time, depth, water speed, compass bearing, flipper stroke frequency, and sound. This approach to data acquisition could lead to a better understanding of the navigation and foraging behavior of large marine predators.
