A day in the life of grey reef shark B (upper) and D (lower) as determined by multi-sensor data-loggers. Depth has been color coded to indicate the behavioral state; low activity (state 1) or high activity (state 2), using acceleration data and HMMs. Video cameras were used to observe behaviors. Horizontal black dashes indicate foraging attempts or success. Vertical black bars indicate when the sharks associated with con-specifics. In upper panel, horizontal blue lines indicate when yellowfin tuna were seen foraging on reef. Horizontal blue lines on lower panel highlight when the shark was associating with schooling barracuda. Note the high abundance of fishes on the mesophotic reef (70 m) in shark B
