They estimate seeing about 60 endangered Right whales in Cape Cod Bay. Half of them were spotted within a single square nautical mile.

“There were whales everywhere we looked, in all different directions and distances,” the researchers said on the aquarium’s blog.

Only about 400 Right whales are thought to inhabit the Atlantic Ocean.
