Mariachis At The Mystic Aquarium

Who says the Beluga whale at the Mystic Aquarium ( where this Mariachi trio was playing a wedding gig) does not like Mexican music.? I just came across this video and I am absolutely fascinated by it.  Wondering if the whale is grooving to the vibrations that carry through the water via the glass on the cage or the sound of the  music or the visual or what.  Clearly, he's having a good time whatever he's into.

Check out the inter- species communication here. It is just awesome.
