摘要：Many cetaceans are killed as a result of intensive anthropogenic impacts, and those that survive often endure wounds or scars. This study is the first report of an Indo-Pacific humpback dolphin (Sousa chinensis) that is missing its upper rostrum. This individual has inhabited Xiamen Bay, Fujian Province, China, for more than 3years. Since the lower jaw and the other part around the upper jaw are intact, it is likely that the upper jaw was entangled in fishing nets or pipelines and subsequently broke off. Without the upper rostrum, this dolphin cannot snap prey, but it may use other feeding strategies - and the fact that this individual has survived for more than 3years without its upper rostrum provides a novel insight into the ability of this species to persist in the wild.
