At first blush, this beluga whale appears to be having fun scaring these kids.
The problem is, anthropomorphism is a funny thing, and for all I know, she could be pissed off as hell and displaying the same behavior she would in the wild if she were being threatened.
So is anyone on this board familiar enough with cetacean behavior to know if she is really showing aggression towards these kids?
IANACE (I am not a cetacean expert) but I think that the beluga initially reacted angrily to the kids tapping on the walls (that’s gotta be LOUD for something with that sensitive hearing) and then, upon seeing that he (err … She? Not up on my beluga sexing skills) was getting quite the reaction, kept at it out of probably boredom more than anything else.
According to what sounds like one of the caretakers in this video, https://www.youtube.com/watch?v=TVOjmX1J70Y, his name is Juno (it’s a ‘he’) and it is an aggressive, territorial display of dominance called “jaw popping”.
ETA:
Got to be a completely unbiased account if even the handlers are calling it aggression. If the handler was saying “oh, he just loves to play with all the guests”, then I’d say we had competing views from two biased sources. But it looks like the experts on both sides of the “whale captivity” debate agree that it is aggressive behavior.
