不列颠哥伦比亚的研究人员捕捉到海狼的视频 利用一条线从水中拉出螃蟹捕捉器 标记了狼使用工具的第一批可能证据 Researchers in British Columbia have captured video of sea wolves using a line to pull crab traps from the water, marking the first possible evidence of tool use in wolves. 这段影片在贝拉贝拉附近拍摄, 显示狼群拖着浮标上岸, 并拖着陷阱到鱼饵上, The footage, recorded near Bella Bella, shows wolves dragging buoys ashore and hauling traps up to access bait, with two wolves observed performing the behavior. 最初被认为受到海洋哺乳动物的破坏,这些陷阱被追溯到狼,狼是灰狼亚种,适应海洋饮食。 Initially thought to be damaged by marine mammals, the traps were traced to wolves, a grey wolf subspecies adapted to a marine diet. 科学家认为,该行为可能通过试验和错误逐渐发展,有可能在社会上传播。 Scientists believe the behavior may have developed gradually through trial and error, potentially spreading socially. 持续24/7监测旨在研究狼群的行动及其对控制侵入性绿蟹的影响。 Ongoing 24/7 monitoring aims to study the wolves’ actions and their impact on efforts to control invasive green crabs.
