The short video begins with the enormous stingray cornering a small squid against the glass of the aquarium and promptly chomping down on it. Visitors can be heard exclaiming in horror. Some even laugh nervously.
The squid shots a jet of blue-black ink everywhere and tries desperately to free itself from its predator. Eventually, however, it disappears into the stingray's mouth.
The person filming then pans to show a number of visitors, including a little girl, looking absolutely stunned at the horror show they've just witnessed inadvertently.
