A gang of boat-ramming orcas has struck again, sinking a sailboat off the coast of Portugal. See the viral video here.

A kayaker in Alaska’s Resurrection Bay had a close encounter with two killer whales when they approached him, then nearly ran right into him.

Jonas Beyer captured some jaw-dropping underwater photos of killer whales, including some close-ups of these dynamic ocean predators.
