Rescuers had called off the effort to save “Timmy,” a humpback whale that had stranded in the Baltic Sea last month. But now a last-ditch attempt to move the creature by barge is underway

Populations of bowhead whales were able to hide from hunters under ice, a new study finds, saving them from extinction. But now, climate change is making that refuge disappear.

Compared to other marine animals, whales have been understudied. Spending their lives in the open ocean, sometimes in very remote locations, whales are more often heard than seen. Consequently, studying whales in their natural environment can prove challenging.

This video was shot by a scuba diver swimming in the Galapagos Islands, located in Ecuador. We see a massive whale shark swimming and then slowly turn back toward the diver, moving slowly and steadily.

Timmy is finally back in the North Sea. The roughly 40-foot humpback, stuck for weeks in the Baltic and written off as doomed in early April, was released Saturday in the North Sea following what the New York Times reports was the fifth attempt to rescue him.
