It's easy to forget that dolphins are fairly closely related to killer whales – their reputations couldn't be more different – yet once you've watched this video, you'll definitely see the resemblance.
Divers Laura and Rich Howard were happily filming a dive off the coast of La Paz, Mexico enjoying some underwater play with some friendly sea lions, when they were called to the surface and saw the dorsal fins of a pod of Orcas – commonly known as killer whales.
When the dive boat headed away from the scene, the whales played for about an hour in the wake, jumping out of the water and getting within inches of the open stern of the boat.
According to Wikipedia, Killer Whales are 'among the fastest marine mammals, able to reach speeds in excess of 30 knots (56 km/h).' And from this footage, they enjoy that kind of speed as much as we do!
