A Rare Gray Whale Was Spotted Off The Coast Of Massachusetts, Baffling Scientists Since The Species Was Thought To Have Been Extinct In The Atlantic For 200 Years

The Northwest Passage is the sea lane that connects the Atlantic and Pacific oceans through the Arctic Ocean along the north of Canada.

The gray whale most recently found in the Atlantic could be an indicator of a future population making their home in the area. It would take decades for a sizable population of gray whales to build up in the Atlantic.

Since scientists have not uncovered any evidence of a breeding population, they still declare the gray whale extinct in the Atlantic.
