科學家在印度洋東南部深海發現一處巨大「鯨魚墓地」,範圍長約1200公里,位於海面下約7公里深的迪亞曼蒂納斷裂帶(Diamantina Fracture Zone)。研究團隊指出,這是目前已知面積最大、深度最深且年代最久遠的鯨魚墓地,部分遺骸可追溯至530萬年前。

綜合外媒報導,鯨魚墓地是鯨魚屍體沉入海底後形成的特殊生態系,龐大鯨屍會成為深海生物的重要食物來源,骨骼與有機物也能長期滋養周邊生物。這處水下墓地由中國、義大利和紐西蘭研究團隊發現,相關論文已發表於《自然》期刊。

研究人員在2023年多次搭乘深海潛水器探勘,在32次下潛期間,從485處鯨魚化石地點和活躍鯨落採集樣本,並發現5處屍骸地點及大量化石,包括距今530萬年的喙鯨Pterocetus benguelae的化石頭骨,以及一具長約5公尺的南極小鬚鯨屍骸,是目前該區發現最大的鯨屍。

研究指出,這些鯨骨能保存數百萬年,可能原因包括鯨骨密度高、足以抵抗噬骨蠕蟲侵蝕,以及遺骸位於深海、不易被塵埃與鬆散沉積物掩埋;加上骨骼表面覆蓋一層由海水形成的礦物質,也可能減緩劣化速度。至於大量鯨魚陳屍同區域,研究人員推測,牠們可能原本就生活在附近並因自然原因死亡,也可能因深海潛水造成疲憊或疾病而死亡,該海床區域形狀類似字母V,也可能將遺骸匯聚至同一處。

研究共同作者、義大利比薩大學古生物學家比亞努奇(Giovanni Bianucci)也指出,研究鯨魚墓地「對於了解生命如何適應這類極端條件十分重要,不只是因為缺乏光線和氧氣,也因為壓力高得驚人」。
