世界最長壽的魚竟逾500歲從16世紀活到現在（示意圖／達志影像）

眾所周知，烏龜是象徵長壽的代表性動物，不過近年來卻有專家學者發現，有遠比烏龜還要長壽的魚類，壽命甚至超過500歲，早在16世紀就已存活至今。

The story behind the story… This is the footage of a giant #Greenlandshark of 4.4 m that was caught and released with satellite tags in 2017. Back then, I shared a screen shot from the video which since has been widely shared, reposted and retweetet hundred of times. Often, when this picture has been shown, it is with a caption reading that this is a 400 yr or even 500 yr old Greenland shark. The shark was big yes, but we cant say anything that precise about its age. My guess is that this particular shark was older than 150 yr but it is obviously a guess. Besides, we have previously estimated the Greenland shark to have a lifespan of at least 272 yr, which was obtained from marine radiocarbon dating of the eye lens nucleus. That is an estimate and it needs verfication one day in the future using another independant method. Mean while, a new marine calibration curve (Marine20) was published last month and running that calibration might affect the current estimates. We will see #greenlandsharkproject

日本媒體《DIAMOND ONLINE》報導指出，人們普遍認為，壽命約為50至80歲的錦鯉相當長壽，但事實上，「格陵蘭鯊」（Greenland shark）的壽命和其他魚類不在同一個層次，動輒200歲以上的壽命，往往讓人瞠目結舌。

尤其是丹麥學家2017年在北大西洋發現了其中一隻格陵蘭鯊的壽命竟然高達512歲，出生時甚至還是16世紀，是目前已知最長壽的有脊髓動物。

據悉，格陵蘭鯊分佈在格陵蘭和冰島一帶，它的長壽秘訣來自於緩慢的生長和行動力，1年僅成長一厘米，要長到150多歲，才達到性成熟的階段，平均壽命為272歲。

此外，它的游速相當緩慢，每3秒才能游1公尺，同時不需要太多食物，新陳代謝很低。即便如此，格陵蘭鯊性格異常兇猛，過去曾被發現體內有著馴鹿、馬及北極熊的屍骸。
