The Sea Life London Aquarium re-opened its doors last week following a 5 million redevelopment.
Work at the aquarium begun in November 2008, during which time access to certain areas was restricted prior to its closure for the final three weeks of the refit.
Now completed, the aquarium will be officially opened by London Mayor Boris Johnson on Friday 17th April.
Contained over three floors in County Hall, on London s south bank, the Sea Life London Aquarium " which was acquired by Merlin Entertainments last year " has been redeveloped into a what the company calls a leading centre of marine conservation.
Among the new features of the transformed aquarium is an acrylic tunnel that takes visitors through the aquariums second-largest display, home to sea turtles and Europe s largest collection of cow-nosed rays, and under a hand-crafted 25 metre-long whale skeleton.
Meanwhile, a glass walkway goes over the aquarium's largest exhibit, the Pacific display, taking visitors to within inches of the sharks beneath them.
Other exhibits include a temple dedicated to seahorses, the story of the River Thames, and an Atlantic coastline display.
Our ultimate aim is to tell a serious eco story in an entertaining way, general manager Toby Forer told the BBC.
We believe we've got the perfect blend of visual spectacle, interactivity and access to aquatic experts to make a visit here a truly memorable and thought provoking experience.
