研究人员报告,不列颠哥伦比亚省外的杀人鲸和海豚合作捕猎鲑鱼。 Killer whales and dolphins cooperatively hunted salmon off British Columbia, researchers report.

研究人员观察到在不列颠哥伦比亚省海岸外的虎鲸和太平洋白面海豚之间可能开展合作,这是第一个记录下来的这种物种间协调案例。 Researchers have observed possible cooperative foraging between killer whales and Pacific white-sided dolphins off British Columbia’s coast, marking the first documented case of such interspecies coordination. 科学家使用无人机和电子标签,记录了鲸鱼和海豚同步移动时的258次繁殖互动,海豚有可能通过回声定位引导鲸鱼到深栖的Chinook鲑鱼。 Using drones and electronic tags, scientists recorded 258 foraging interactions where whales and dolphins moved in sync, with dolphins potentially guiding whales to deep-dwelling Chinook salmon using echolocation. 海豚在没有侵扰的情况下把剩剩的鱼渣挖出来,鲸鱼继续不受干扰地喂养。 Dolphins scavenged leftover fish scraps without aggression, and whales continued feeding undisturbed. 这项研究于2025年12月11日发表在《科学报告》中, 提出一种互利关系, 尽管研究人员提醒该行为的全部性质仍未证实, The study, published in Scientific Reports on December 11, 2025, suggests a mutually beneficial relationship, though researchers caution the behavior’s full nature remains unproven and requires further study.
