在这里，我们报告说，雄性宽吻海豚的同步浮出水面与联盟成员身份有关，并且合作联盟成员之间的同步在社会行为期间比非社会行为期间更常见，特别是在与雌性配偶的“激烈”社会行为（例如骑乘、展示、追逐）期间。三个雄性的联盟在所有成员同步参与的程度上有所不同，这可能反映了联盟团结度以及联盟与雌性联盟的程度的差异。雄性围绕雌性进行的精心展示与本文报道的联盟成员的同步出现之间没有间断，这表明同步是一种适应性信号。如果是这样，我们在使用同步作为人类和宽吻海豚的联盟信号方面就有了显着的趋同。然而，无论是适应性信号还是接近度的相关性，同步性都将成为研究海豚社会关系的有用工具。 (c) 2006 年动物行为研究协会。由爱思唯尔有限公司出版
Here we report that synchronous surfacing in male bottlenose dolphins is associated with alliance membership and that synchrony between members of cooperating alliances is more common during social behaviour than during nonsocial behaviour, especially during bouts of 'intense' social behaviour (e.g. mounting, displays, chasing) with female consorts. Alliances of three males varied in the degree to which all members participated in synchrony, possibly reflecting differences in alliance unity and the extent to which alliances consort with females. The lack of a discontinuity between the elaborate displays that males perform around females and the synchronous surfacing of alliance members reported here suggest that synchrony is an adaptive signal. If so, we have a remarkable convergence in the use of synchrony as an alliance signal in humans and bottlenose dolphins. However, whether an adaptive signal or a correlate of proximity, synchrony will be a useful tool in the study of delphinid social relationships.
