Identifying a tiger shark from a drone: what to look for in the water

From the drone, Lauren Landers Sailing looks for a large, dark spot that is moving. A tiger shark can be distinguished from other species nearby by its more square, broader head, unlike the oceanic blacktip which has a pointier nose. The other sharks in the area are noticeably smaller. Waves can make it hard to confirm the square head or see the stripes, but the overall shape and size relative to other sharks give it away. She describes being 90% confident she identified a tiger shark on one pass, even though the waves prevented a perfect view.
