大白鲨卡拉（Kara）从加利福尼亚被追踪，于2026年3月抵达温哥华岛，这是与猎物和气候变化相关的北方罕见目击事件。 Great white shark Kara, tracked from California, reached Vancouver Island in March 2026, a rare northern sighting linked to prey and climate shifts.

2026年3月在温哥华岛附近发现一只名为卡拉(Kara)的成年雌性大白鲨, A mature female great white shark named Kara, tracked since being tagged off California in October 2025, was detected near Vancouver Island in March 2026, marking a rare northern sighting. Kara是该研究中第一只到达不列颠哥伦比亚省水域的鲨鱼, Measuring about five meters and weighing 1,000 kilograms, Kara is the first shark in the study to reach British Columbia waters, though great whites have been seen in the region before. 研究人员认为,她的行动可能与猎物的可获性有关,例如海豹和海狮种群增加,并表明海洋生态系统中气候驱动的变化可能导致更频繁的北方目击。 Researchers believe her movement may be linked to prey availability, such as increasing seal and sea lion populations, and suggest climate-driven shifts in marine ecosystems could lead to more frequent northern sightings. 虽然这种流动并不常见,但科学家强调跟踪数据对于了解移徙、育种模式和养护需要的重要性。 While such movements are uncommon, scientists emphasize the importance of tracking data for understanding migration, breeding patterns, and conservation needs.
