两位马萨诸塞州捕鱼爱好者Nate Rouette和Nelson Rouette在7月下旬于法尔茅斯近海捕获一条5英尺长的幼虎鲨[1]。这条热带物种通常生活在加勒比海等温暖南方水域[1]，其在新英格兰北方海域的出现引起科学家关注。
新英格兰水族馆海洋生物中心的科学家John Chisholm表示："也许它们来到这里是因为条件合适。有食物，有温暖的水域"[1]。科学家认为，这一事件反映出海洋变暖的现实——虎鲨等多种海洋生物正因全球海洋温度上升而向北迁移[1]。虎鲨成年个体通常超过15英尺，体重可达1400磅[1]。
Two fishing enthusiasts captured a juvenile tiger shark measuring five feet in length off Falmouth, Massachusetts, in late July.[1] Tiger sharks are tropical species typically found in warm southern waters such as the Caribbean, making this catch noteworthy for the region.[1] The brothers, identified as Nate Rouette and Nelson Rouette, subsequently released the animal.[1]
Scientists view the capture as potential evidence of ocean warming driven by climate change.[1] John Chisholm, a marine biologist with the New England Aquarium's marine conservation center, suggested that favorable conditions may have drawn the shark northward.[1] "Perhaps they came here because conditions are right. There's food, there's warm water," Chisholm stated.[1] Adult tiger sharks typically exceed fifteen feet in length and weigh approximately 1,400 pounds.[1] In recent years, various marine species have migrated northward as global ocean temperatures continue to rise, with tiger sharks among those shifting their ranges in response to these changing conditions.[1]
