Marine biologist Alice Barbarioli waits with her camera trained on(对准；瞄准) the horizon. A few minutes earlier, the hydrophone beneath the Pelagos research vessel detected codas – the sequence of clicks sperm whales use to communicate.(几分钟前，佩拉戈斯号科考船下的水听器探测到了尾音——抹香鲸用来交流的一连串咔嗒声。)
海洋生物学家爱丽丝·巴尔巴里奥利举着相机，镜头对准地平线，等待着。几分钟前，佩拉戈斯号科考船下的水听器探测到了尾音——抹香鲸用来交流的一连串咔嗒声。
The sperm whale reveals its head and dorsal fin as those onboard the vessel in the Pelagos sanctuary, a conservation area established to protect marine mammals in the north-western Mediterranean, rush to take photos and note the rhythm of its breathing.(这头抹香鲸露出了头部和背鳍，佩拉戈斯保护区内船上的人们急忙拍照，并记录它呼吸的节奏。) After a few minutes, the animal arches(弓起) its back, and begins to head back into the depths of the sea. They wait to catch a glimpse of(瞥见；看一眼) its tail.
这头抹香鲸露出了头部和背鳍，佩拉戈斯保护区内船上的人们急忙拍照，并记录它呼吸的节奏。佩拉戈斯保护区是西北地中海为保护海洋哺乳动物而设立的一片保育区。几分钟后，这头鲸弓起背，开始返回深海。他们等待着，想看一眼它的尾巴。
Barbarioli, the lead researcher of the citizen-science expedition, organised by the Tethys Research Institute, immediately notices an injury on its left fluke: “Given how precise the mark is, it’s probably the result of a [vessel] collision,” she says.(巴尔巴里奥利是这次公民科学考察的首席研究员，考察由泰西斯研究所组织。她立刻注意到鲸鱼左尾叶上有一处伤痕：“从痕迹的精确程度来看，这很可能是[船只]撞击造成的，”她说。)
