As far as I know, Orcas are friendly.
This Orca is happily swimming along next to the wake of this boat, which is perhaps what is attracting it. Orcas can swim at about 35 mph.
Orcas are the largest members of the dolphin family. Because of their size, they've often been called killer whales although they almost never kill humans. They are at the top of the food chain so they are not prey except to humans. So that's ironic.
The largest orca ever recorded was 32 feet long and 22,000 pounds.
