Humpback Whales Make Longest Mammal Migration

Humpback whales in the Atlantic have been tracked making the longest migration on record. New Scientist reports that seven individual whales swam 5,160 miles between Antarctica and the Caribbean coast of Costa Rica. One mother and calf made the trip in 161 days. While some researchers claim that gray whales hold the record for longest mammalian migration—from Mexico to the Arctic, at 4700 miles—no individual gray whale has been documented travelling the full extent of their migratory range, and it’s possible that no individual makes the entire migration. Kristin Rasmussen at Cascadia Research Collective in Olympia, Washington, says the new humpback data are important in light of proposals to hunt humpbacks, including Japan’s decision to catch 50 humpbacks each year as part of its [bogus] scientific whaling program. “Whales don’t respect political boundaries,” she says. “Killing whales in one area could potentially impact their population half way around the world.”–Julia Whitty

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
