2025年1月,在南极洲冰冷的深水中拍摄了3-4米沉睡鲨鱼,这是该地区第一个经证实的目击。 A 3-4 meter sleeper shark was filmed in Antarctica’s freezing deep waters in Jan 2025, the first confirmed sighting in the region.

2025年1月，在南设得兰群岛附近的南极海域490米深处，有一条3至4米长的沉睡鲨被摄像机捕捉到，这是该地区近冰水域首次确认鲨鱼被目击。 A sleeper shark, 3 to 4 meters long, was captured on camera in January 2025 at 490 meters depth in the Antarctic Ocean near the South Shetland Islands, marking the first confirmed sighting of a shark in the region’s near-freezing waters. 该片段由Minderoo-UWA深海研究中心拍摄,显示水中缓慢移动的鲨鱼仅高于1.27摄氏度的冰层,其深度是阳光无法到达的深处。 The footage, taken by the Minderoo-UWA Deep-Sea Research Centre, shows the slow-moving shark in water just above freezing, 1.27°C, at a depth where sunlight does not reach. 研究人员感到惊讶,因为南极洲以前没有鲨鱼的记录,尽管鲨鱼很可能留在海洋分层水柱最温暖的一层。 Researchers were surprised, as no prior records of sharks existed in Antarctica, though the shark likely stayed in the warmest layer of the ocean’s stratified water column. 这一发现是在南半球夏季有可能进行监测时发现的,表明沉睡鲨鱼可能食用沉没的海洋遗骸,并突出表明偏远地区对深海生物的了解有限。 The discovery, made during the Southern Hemisphere summer when monitoring is possible, suggests sleeper sharks may feed on sunken marine remains and highlights limited knowledge of deep-sea life in the remote region.
