加拉帕戈斯群岛附近的抹香鲸群体(主要是雌性)产生咔哒声的速度取决于两个主要因素：在场的鲸鱼数量和群体的行为状态。当鲸鱼处于它们的主要行为状态(约占它们时间的80%)，长时间潜入深海，通常单独或成对出现在水面上时，每头鲸鱼发出一连串的咔哒声，相互点击的间隔约为0.5 S，约占70%的时间。大约10%的时间，群体保持在表面或接近表面，个体成员组成包含五个以上个体的集群，并且通常保持沉默。群体行为有时介于这两个极端之间，一些鲸鱼在中等大小的鲸鱼群的表面沉默，而另一些鲸鱼在深处发出咔哒声。点击率可以作为抹香鲸行为、群体大小和/或现有群体数量的指标。在我们的研究中，团体经常联系在一起，而且更频繁地…
The rate of production of clicks by groups of (mainly female) sperm whales off the Galapagos Islands was dependent on two principal factors: the number of whales present and the behavioral state of the group. When the whales were in their principal (occupying about 80% of their time) behavioral state, diving deep for prolonged periods and usually being seen at the surface singly or in pairs, each whale made trains of clicks with an interclick interval of about 0.5 s about 70% of the time. About 10% of the time, the groups remained at or near the surface, with individual members forming clusters containing greater than five individuals, and being generally silent. Group behavior was sometimes intermediate between these extremes, with some whales silent at the surface in medium‐sized clusters, and others clicking at depth. Click rate can be used as an indicator of the behavior of sperm whales, the size of a group, and/or the number of groups present. In our studies, groups associated often, and more frequen...
