POV: BRUV Episode 3 - Grey Patrol If you’re cruising a reef in Vanuatu, like you see here, you’re in the territory of the grey reef shark (Carcharhinus amblyrhynchos). These sleek and social sharks are apex predators whose job it is to create a landscape of fear. While that sounds intense (and it is!), they are providing a critical service that helps prevent overgrazing of the reef and ensures that only the healthiest fish populations survive. Baited remote underwater video systems (BRUVs) are a scientific surveying tool that uses unmanned high-definition cameras to spot and record species on a reef. In this #POVBRUV series, we leave the humans behind and watch what happens.
