An adorable video making its way around Facebook and Twitter focuses on a mariachi band and a beluga that seems to be enjoying the music.
Mariachi Connecticut, a Hartford-based mariachi band, was performing during a wedding at Mystic Aquarium last month and started playing for a beluga whale.
The video has become an Internet hit since being posted by Bill Kurtz of West Haven, a guest at the July wedding of Kimberly Mikenis and Kevin Van Aelst of New Haven.
But Mystic Aquarium senior trainer Kelly O'Neil tells the New Haven Register that Juno, the 1,200-pound beluga on the video, has been trained to bob in response to certain arm movements, and was apparently responding to the movements of the band's guitar player.
O'Neil says the whale's apparent interest in the wedding was probably due to the music's vibrations, those physical cues and the whales' natural curiosity.
Still, watch how the whale reacts. It's worth it.
