有一个更大的问题仍需回答:这些圈养动物存在的目的是为了让人们了解海洋中的生命,还是仅供我们娱乐?
词汇 dolphinariums 海豚表演馆
in captivity 被圈养的,人工驯养的
human-animal bonds 人与动物的纽带、关系
in the wild 在野外环境中
你知道吗? Dolphins have their own individual whistle. When greeting, they first produce their signature whistle to identify themselves and have been shown to remember a member of their original group’s own whistle years after last hearing it.
海豚能吹出有各自特色的口哨。每当见面打招呼时,它们会先发出自己的哨声,从而让同伴识别自己,有研究还发现海豚能记住其数年前听到的来自其原群体成员的哨声。
问题答案 Professor Shultz says that the study doesn't tell us whether dolphins are happier in captivity or nearly as happy as they would be in the wild.
