We have had an opportunity to dive with Birds Adventures in Crystal Springs, Florida and dive in Three Sisters springs in Crystal River, the place where this video is shot.

Birds has a mandatory briefing video called "Minding Manatee Manners" that explains without confusion exactly what you can and cannot do when interacting with these magnificent wild animals.

I personally thought the Manatee Manners video was just common sense but time seems to always prove that sense is not so common, and this video here demonstrates it.

The perpetrators here look like teens and early 20's types, not divers.
