The video shows hundreds of white-sided dolphins in a panic-stricken dash with killer whales chasing after them. The viewer can sense the panic of the dolphins as their fins churn the blue bay waters white in their frantic dash for safety.
The scene was filmed in Hyacinthe Bay, British Columbia, Canada and uploaded to YouTube on June 18 by stevieandyoyster.
Killer whales (Orcinus orca), also referred to as orca whale or simply orca, are toothed whales belonging also to the dolphin family. They are found in the cold waters of the Antarctic regions and in tropical seas. The prey on fish, sea lions, seals, walruses, and dolphins, as we see in the video. They are considered apex predators because they have no natural predators.
They are social animals with some populations composed of matrilineal family groups that scientists rank among the most stable of animals species. Their vocal behavior and hunting techniques, which are often specific to a particular group, are passed across generations and are considered manifestations of culture.
Killer whales are generally not considered a threat to humans
