Spontaneous ejaculation, which is defined as the release of seminal fluids without apparent sexual stimulation, has been documented in boreoeutherian mammals. Here we report spontaneous ejaculation in a wild Indo-Pacific bottlenose dolphin (Tursiops aduncus), and present a video of this rare behavior. This is the first report of spontaneous ejaculation by an aquatic mammal, and the first video of this behavior in animals to be published in a scientific journal.
自发性射精是指在没有明显性刺激的情况下精液的释放，已在有袋类哺乳动物中得到证实。在这里，我们报告了一只野生印太瓶鼻海豚（Tursiops aduncus）的自发性射精，并展示了这段罕见行为的视频。这是水生哺乳动物自发性射精的首例报告，也是首例在科学期刊上发表的该行为的动物视频。
