I had not seen this...I'm sure it is old and many have seen it already..good footage of how the fins move when they are doing drive by action and surface nudges imo..
the one scene about midway in the clip where the tail is sticking out of the water pretty high and swishing back and forth and the dorsal is only just barely sticking out the water ,is a lot like the movements I saw in Monterey ---except it was harder to see it behind my shoulders...good side shot here
