Kuroshio Sea - 2nd largest aquarium tank in the world

The fish tank that's so big it can hold FOUR whale sharks

It certainly beats watching a lonely goldfish swimming round its tiny bowl.

This is one of the world's biggest fish tanks - so big that it's even been named the Kuroshio Sea.

Located in the Churaumi Aquarium in Okinawa, Japan, the enormous tank is some ten meters deep, 35 meters wide and 27 meters long.
