Using an omnidirectional video logger to observe the underwater life of marine animals: Humpback whale resting behaviour
Animal-borne video loggers are powerful tools for investigating animal behaviour because they directly record immediate and extended peripheral animal activities; however, typical video loggers capture only a limited area on one side of an animal being monitored owing to their narrow field of view....
