Dubai Mall Aquarium

For the whole of January it's Dubai Shopping Festival so I went to Dubai Mall to see if there were any bargains to be had, some time and a substantial amount of walking later I remained empty handed.
While in the mall I stopped off to have a bit of a gawp at the aquarium.
I hope the picture gives an idea of just how big it is, everytime I see it I have to stop and look even if only for a few seconds.
There must be at least a dozen big sharks in there together with rays and probably thousands of little fish.
