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

It holds a staggering 7,500 tonnes of water  -  roughly equal to three Olympic-sized swimming pools.

Eighty species live in the Kuroshio Sea tank, including yellow-fin tuna, bonito (a type of large mackerel) and manta rays.

But the daddy of them all is the world's biggest fish, the whale shark  -  which can grow to be 12 metres long and needs a quarter of a tonne of food every week.

Only three aquariums in the world have tanks large enough to house these giant creatures.
