It's 25 years since the region's first Sealife Centres opened and the man who cut the ribbon back then has returned to mark the occasion.
Former TV weatherman Michael Fish was back in Great Yarmouth to mark the quarter of a century since the seafront tourist attraction first opened.
There are now Sealife Centres all over the country but the ones in Hunstanton and Great Yarmouth were among the first.
There are more than a thousand creatures at the Great Yarmouth Sealife Centre from sharks to seahorses to penguins and rays.
In the 25 years there have been many memorable moments, for instance, a feisty mantis shrimp managing to shatter the glass of its tank and when they wanted nurse sharks Hercules and Aphrodite to get it on they piped in Barry White music into their tank and it worked.
These days twenty million people a year visit the fifty Sealife centres and six aquariums around the world.
