一条幼年座头鲸周末游入澳大利亚新南威尔士州克拉伦斯河，深入河流约11公里后搁浅在浅水沙洲并死亡 1。这条鲸鱼周六下午首次被报告，在30分钟内死亡 1。当局于周日将鲸鱼尸体拖出大海，并随后向海滩使用者发布警告，建议避免冲浪、游泳和潜水，因为周边鲨鱼活动明显增加 1。
鲸鱼科学家范妮莎·皮罗塔指出，虽然座头鲸进入河流的情况罕见但并非前所未有 1。鲸鱼可能因好奇、迷路或健康状况不佳而误入内陆水域 1。澳大利亚东海岸每年约有50000条座头鲸进行迁徙 1。历史上曾有类似事件发生——2020年卡卡杜国家公园东鳄鱼河内有3条座头鲸进入，其中一条游入河流达30公里 1。值得注意的是，仅在不到一周前，珀斯城市海滩还发现了另一条座头鲸尸体 1。
A juvenile humpback whale ventured approximately 11 kilometers upstream into the Clarence River in New South Wales, Australia, over the weekend before becoming stranded in shallow waters and dying.1 The cetacean was first reported on Saturday afternoon and died within 30 minutes of discovery.1 Authorities extracted the carcass from the river on Sunday, prompting officials to issue a shark warning to beach users, advising against surfing, swimming, and diving in the area due to increased shark activity near the whale remains.1
While such incidents remain uncommon, whale scientists confirm they are not unprecedented.1 According to whale expert Vanessa Pirotta, "the main part of the east and west coast populations are moving south toward Antarctica right now."1 The young humpback's unusual inland journey may have resulted from curiosity, disorientation, or poor health.1 The occurrence parallels a 2020 incident at East Alligator River in Kakadu National Park, where three humpback whales entered the river, with one traveling 30 kilometers upstream.1 Australia's east coast typically experiences the migration of approximately 50,000 humpback whales annually.1 The incident came less than a week after a separate humpback whale carcass was discovered on a beach near Perth.1
