Have you ever wondered if the animals on the other side of the glass at the Aquarium could see you?

We all do it! Tap the glass, wave to the fish or animals, wiggle your fingers as bait to see if anything will react. But what exactly can the animals on the other side of the glass see, if anything?  Can they see you as well as you can see them? Or are they simply looking at their reflections on the glass?

Watch as this kid tries playing with an otter - on the other side of the glass. Even trying to change directions quickly and fake the otter out as it chases along side.
