在一项为期21个月的研究中，53只瓶鼻鼠海豚通过它们背鳍的照片被识别出来。他们以小的亚群（平均人数= 15）旅行，由5只稳定的核心动物和其他个体组成，这些个体在不同的观察中变化很大。
During a 21-month study, 53 individual bottle-nosed porpoises were recognized by photographs of their dorsal fins. They traveled in small subgroups (mean size = 15) composed of a stable core of five animals plus other individuals that varied greatly from sighting to sighting.
