Check out this awesome clip posted on Youtube by Ben Biber on May 4. There was no information included with the video, but the footage speaks for itself.

The coolest thing about this clip is how effortlessly the killer whales are able to swim behind the boat. The not coolest thing about the clip? The peanut gallery screaming: “OH MY GOSH! … Jack Hanna eat your heart out!”

(Editor’s note: May want to watch without audio).
