A trans-Pacific movement reveals regular migrations of humpback whales Megaptera novaeangliae between Russia and Mexico
Humpback whales Megaptera novaeangliae undertake extensive annual migrations, have complex migratory patterns, and have held several mammalian long-distance movement records. Here, we report on a whale known to feed in the Russian Far East that was sighted in breeding areas on either side of the Nor...

Humpback whales Megaptera novaeangliae undertake extensive annual migrations, have complex migratory patterns, and have held several mammalian long-distance movement records.

This is the longest published distance (11261 km great-circle route) between 2 unique sightings of a photo-identified humpback whale to date.
