They Swim Up To 40 Miles Per Day

Orcas have evolved to swim as far as 40 miles in one day to forage for food, exercise, and socialize. In addition to swimming, killer whales will dive several times per day to depths of 100 to 500 feet below the water's surface. They are naturally inclined to travel far and dive deep, which is part of the reason killer whales often struggle in captivity, where tanks can't grant the same range and the mammals sometimes develop boredom and stress due to repetitive activities.
