不过， Curé和她的同事在2019年对挪威长肢领航鲸的一项新研究显示，当地的领航鲸在听到本地食鱼性虎鲸族群的叫声时会表现出典型的集体袭扰行为，不同的领航鲸族群会集结起来汇成规模更大的超级大群，并且会大声喊叫以壮声势。但在听到当地不存在的陌生的食海兽性虎鲸的叫声时，领航鲸虽然仍然会试图靠近声源一探究竟，它们的表现却要谨慎得多。它们会减少甚至停止摄食行为，在海面上花的时间明显缩短，而且在靠近声源时会选择采用缩小个体间距这种明显的防御型阵型。
因此，我们可以看到，领航鲸不仅能够识别出虎鲸的叫声，它们对于自己生活环境里其他的鲸鱼也很熟悉，它们其实很清楚当地食鱼性虎鲸族群是一个危险系数相对较低的威胁，而在听到陌生的虎鲸时也绝不会愚勇冒进。挪威领航鲸对外地食海兽性虎鲸的表现究竟是处于对其刻在DNA里的恐惧，还是出于对陌生虎鲸族群来者不善的基本尊重，还需要通过后续研究进一步探索。
