Rare gray 鯨 以前 extinct from the 大西洋 for more than 200 years is seen off Nantucket after making a trip up from Florida coast
- A gray 鯨, which has been extinct from the 大西洋 Ocean for more than 200 years, was spotted off the coast of Nantucket, Massachusetts, on Friday
- Scientists from the New England 水槽 said the 鯨's 移住 was most likely a result of the 影響s of 気候 change on the Northwest Passage
- The?水槽 believes that the 鯨 設立する this month was likely the same animal spotted in Florida late last year and has just traveled up the coast
The New England 水槽 has 株d new photos of a rare gray 鯨 off the coast of Nantucket that they believe was 以前 spotted in Florida last December.
The gray 鯨, which has been extinct from the 大西洋 ocean for more than two centuries, was spotted 30 miles off the coast of Nantucket last Friday.
The 水槽 sent out an 空中の マスコミ team to circle the 鯨 and take phots for 45 minutes to 確認する it was indeed a gray 鯨.
'My brain was trying to 過程 what I was seeing, because this animal was something that should not really 存在する in these waters,' 研究 専門家技術者 Kate Laemmle said in a 声明 地位，任命するd by the 水槽.?
'We were laughing because of how wild and exciting this was ― to see an animal that disappeared from the 大西洋 hundreds of years ago!'

The 鯨, which can 重さを計る 60,000 続けざまに猛撃するs, typically lives in the northern 太平洋の Ocean
There have been five 観察s of the animal in 大西洋 and Mediterranean waters in the last 15 years
Although gray 鯨s typically live in the northern 太平洋の Ocean, this one looked awfully familiar to 研究員s at the 水槽.
The 水槽 hypothesized that the 鯨 pictured this month was likely the same animal spotted off the coast of Florida late last year.
While gray 鯨s disappeared from the 大西洋 during the 18th century, over the last 15 years, there have been five 観察s of the animal in 大西洋 and Mediterranean waters, the 水槽 said in a 声明?
Scientists said the 鯨's 移住 was probably indicative of the 影響s of 気候 change.?
'The Northwest Passage, which connects the 大西洋 and 太平洋の through the 北極の Ocean in Canada, has 定期的に been ice-解放する／自由な in the summertime in 最近の years, partly 予定 to rising 全世界の 気温s,' the 水槽 said.
This means that more gray 鯨s could 潜在的に travel the Northwest Passage during the summer?when 普通は they would have been 封鎖するd.

Scientists せいにする the 鯨's unusual 移住 to 気候 change
O'Brien, an associate 研究 scientist with the Anderson Cabot 中心 for Ocean Life at the New England 水槽,?said the animal's arrival off New England serves 'as a 思い出の品 of how quickly 海洋 種類 答える／応じる to 気候 change, given the chance.'
So how can you tell a gray 鯨 apart from its 相当するものs?
Unlike the 猫背／ザトウ鯨 鯨, which is more 一般的に sighted in New England, gray 鯨s can be id entified by their 欠如（する） of a dorsal fin and mottled 外見.?
They also sound different; gray 鯨s make gurgles, grunts and croaks while 猫背／ザトウ鯨 むちの跡s produce what is known as 'songs' as it is reminiscent of human 声のs.
While they were almost 追跡（する）d into 絶滅 as a result of 商業の 捕鯨, the International Union for 自然保護 of Nature considers the 種類 to be at a point of 'least 関心' as they have 回復するd in 全住民.?
However, the western 全住民 of 鯨s that lives off Asia is considered to be 危うくするd by the organization.
The gray 鯨 can 重さを計る up to 60,000 続けざまに猛撃するs, 類似の to that of a 猫背／ザトウ鯨.
