Sneak peek behind Brighton Sea Life renovations

The world's oldest operating aquarium is undergoing a renovation costing almost £3m.

The largest tank at the Brighton Sea Life centre was completely drained and hundreds of creatures were taken to temporary homes elsewhere.

The display re-opens in a few weeks time with a "night and day" theme, and the largest collections of sharks and rays anywhere under one roof.

It is the first time this giant tank has been totally drained since the famous dolphins Missie and Silver were released from the aquarium and taken to new lives in the Caribbean.

The huge ocean display is being re-filled with three quarters of a million litres of salt water.

The project costing £2.7m became possible when work started immediately above the aquarium to build a new hotel.

In the state of the art display which has now been created, the first sea creatures will start arriving back home over the next few weeks.
