The orcas are members of the J, K and L pods, the three families that make up the southern resident orca population in the Pacific Northwest. The population was decimated in the 1970s when an entire generation of baby orcas was captured and carted off to places like SeaWorld. The families have spent the past four decades trying to recover and are currently listed as endangered.
Only one of the kidnapped babies is still alive: Lolita was captured at age 4 and has spent the past 45 years at the Miami Seaquarium in the smallest orca tank in America while her family survives off the Washington coast.
But places like SeaWorld and Miami Seaquarium are pointless when you can have experiences like these on the orcas' own terms. As Feis notes in the video description, she got to experience the real SeaWorld.
You can watch the videos below for the full encounter. (The second video features more whale footage.)
