Blacktip Reef Shark Circling the Research Boat

A blacktip reef shark swims around our research boat at Palmyra atoll. In total, we received accelerometer data from four blacktip reef sharks. We calculated overall dynamic body acceleration and used this metric as a proxy for general activity levels. The hidden Markov model was able to distinguish between high level and low level activity, allowing us to understand when the shark was more active! (© Yannis P Papastamatiou)
