格陵兰鲨新发现？

1.Puzzled scientists are trying to figure out what a giant shark native to the Arctic was doing in considerably warmer waters thousands of miles south of its frigid home.

困惑的科学家们正试图弄清楚，一只原产于北极的巨型鲨鱼在其寒冷的家乡以南数千英里的相当温暖的水域里做了什么。

2.Researchers from Florida International University and the Belize Fisheries Department recently discovered a Greenland shark, which typically lives in the freezing waters of the Arctic, in the tropical waters of the Caribbean Sea while working with local Belizean fishermen to tag tiger sharks, according to a press release from the university.

佛罗里达国际大学和伯利兹渔业部的研究人员最近在与当地伯利兹渔民一起给虎鲨贴上标签时，在加勒比海的热带水域发现了一种格陵兰鲨，这种鲨鱼通常生活在北极的寒冷水域。

3.The shark was swimming near the Belize Barrier Reef, the second-longest barrier reef in the world, the scientists said. 

科学家们说，这条鲨鱼当时正在世界上第二长的堡礁伯利兹珊瑚礁附近游泳。

4.The discovery marks the first time a shark of its kind has been found in western Caribbean waters.

这一发现标志着在加勒比西部水域首次发现这种鲨鱼。

5.Devanshi Kasana, a marine biologist at FIU and a Ph.D. candidate in the university's Predator Ecology and Conservation lab, at first thought that what she was looking at was a sixgill shark, which is known to live in the deep waters off coral reefs.

德凡什·卡萨纳是弗罗里达国际大学的海洋生物学家，也是该大学捕食者生态与保护实验室的博士研究生，起初，她以为自己看到的是六鳃鲨，这种鲨鱼生活在珊瑚礁附近的深水中。

6."I knew it was something unusual and so did the fishers, who hadn't ever seen anything quite like it in all their combined years of fishing," Kasana said in a statement.

卡萨纳在一份声明中说:“我知道这是不寻常的事情，渔民们也知道，他们在所有的捕鱼生涯中从未见过这样的事情。”

7.Kasana then conferred with her adviser and other shark experts, texting a photo of the creature. 

卡萨纳随后与她的顾问和其他鲨鱼专家进行了讨论，并发了一张鲨鱼的照片。

8.The final determination was that it was "definitely" in the sleeper shark family due to its large size, and was most likely a Greenland shark or a hybrid between a Greenland shark and a Pacific sleeper shark, according to FIU.

据弗罗里达国际大学的说法，最后的判断是，由于它的体型很大，它“肯定”是卧鲨家族的一员，很可能是格陵兰鲨或格陵兰鲨和太平洋卧鲨的杂交品种。

9.It is unclear whether the researchers were able to tag the shark.

目前还不清楚研究人员是否能够给鲨鱼贴上标签。

10."This finding is so exciting because it suggests that these ancient predators are potentially roaming the world's oceans from pole to Equator, but staying very deep in tropical waters," Kasana, who is still in Belize, said in an emailed statement to ABC News. 

“这一发现非常令人兴奋，因为它表明，这些古老的捕食者可能在世界各地的海洋中漫游，从极点到赤道，但停留在热带水域的深处，”仍在伯利兹的卡萨纳在发给美国广播公司新闻的电子邮件声明中说。

11."It feels great to be a part of this and be a part of what could be the first step in protecting sleeper sharks in this region."

“能参与其中，成为保护该地区睡鲨的第一步的一部分，感觉很棒。”

12.Little is known about the Greenland shark. 

关于格陵兰鲨人们知之甚少。

13.The half-blind shark subsists by scavenging on polar bear carcasses and can live up to 250 and perhaps even 500 years, according to the National Oceanic and Atmospheric Administration, making them the longest-living vertebrate known to science.

据美国国家海洋和大气管理局称，这种半盲鲨鱼靠吃北极熊的尸体为生，可以活到250年，甚至500年，是科学界已知的最长寿的脊椎动物。

14.Greenland sharks are also massive in size and can reach up to 23 feet long and weigh up to 1.5 tons, according to National Geographic.

据《国家地理》报道，格陵兰鲨体型庞大，可达23英尺长，重达1.5吨。

15."Because little is known about them, that means nothing can be definitively ruled out about the species," the scientists said.

科学家们说:“由于对它们知之甚少，这意味着不能完全排除关于这个物种的任何可能性。”

16. "Greenland sharks could be trolling the depths of the ocean all across the world."

“格陵兰鲨可能在世界各地的海洋深处游荡。”

17."Great discoveries and conservation can happen when fishermen, scientists and the government work together," said Beverly Wade, director of the Blue Bond and Finance Permanence Unit in the Office of the Prime Minister of Belize. 

“当渔民、科学家和政府共同努力时，伟大的发现和保护就会发生，”伯利兹总理办公室蓝色债券和金融永久部门主任贝弗利·韦德说。

18."We can really enhance what we can do individually, while also doing some great conservation work and making fantastic discoveries, like this one."

“我们就可以增强我们个人的能力，同时也可以做一些伟大的保护工作，做出一些奇妙的发现，就像这次一样。”
