In March 2018, Norwegian scientists put a tracker on a young female Arctic fox to study her behavior. The fox then set off on a 3,506-kilometer journey from Norway to Canada. She completed the journey in just 76 days, running an average of 46 kilometers a day. Arctic foxes are known for their ability to survive in harsh polar conditions. However, no fox had ever been recorded reaching such high speeds and covering such a vast distance before, not to mention the fact that it was done in a short amount of time.
2018 年三月，挪威科学家在一只年轻的雌性北极狐身上安装了追踪器来研究她的行为。随后，这只狐狸踏上了从挪威到加拿大、长达 3506 公里的旅程。她只花了七十六天就完成了这趟旅程，平均每天奔波四十六公里。北极狐以其在恶劣的极地条件下生存的能力而闻名。然而，以前从未记载有狐狸能够达到如此高的速度和移动如此远的距离，更不用说这是在很短的时间内完成的。
