A trip to the aquarium is usually a chance for children and adults to observe mammals and animals go about their business while we watch behind a pane of glass.

In this incredible video, however, we see a Beluga Whale not only become aware of the childrens presence, but actually engage, tease and startle them several times.

While the whale at first seems oblivious to the children and appears to be calmly swimming around his tank, he soon returns and presses his face against the glass and shrieks at the children to scare them.
