A moving passage guides you through the transparent tunnel surrounded by a colorful array of underwater life: sharks, rays and 200 species of rare fish from around the world. This is a very popular attraction, so be prepared to fight the crowds and the screaming children. There is also a warship model exhibition, a touch zone with ocean beasties, and a doodle room for the kiddies. A highlight of the visit is watching divers feeding the sharks. Recently penguins from the South Pole have hatched their young there.
