Interaction Analysis in Hunting Behavior of Finless Porpoises

Finless porpoises (Neophocaena asiaeorintalis) usually live in a relatively small group. Aggregated porpoises prey on fish simultaneously and they do not show explicit allotted roles like other dolphins. However, whether each individual hunt fish independently from others is not clear. In this study, we tried to find dependency in porpoises' hunting using movies of their feeding taken by a drone.
