The Underwater World Experience echnically, these pictures belong under the Sentosa Experience page, because Underwater World is located on Sentosa. Still, I believe these pictures deserve their own category. Unterwater World is a huge collection of all kinds of fish and other stuff that dwells underwater. The main attraction is the tunnel, in which you actually go into a tunnel through a big aquarium. That way, you can see fish all around you. That's how the title picture turned out: A shark swam right over my head. Really cool... The shark right over my head (Here it is in the big version. Ever seen a shark from underneath?) Real piranha (as I learned, these little fish can eat an entire human within 20 seconds... That sounds fun.)
