Sea Life counts more than 30,000 aquatic creatures in annual stocktake Aquarists armed with their measuring tapes and clipboards counted more than 30,000 creatures at Sea Life aquariums across the UK as they undertook their annual stocktake.
The UK’s first rescued Alaskan sea otters, Ozzy and Ola, were also weighed in London, measuring 27.5 and 22.8 kilograms respectively.
“Count and Clean is one of our most cherished and important activities at Sea Life London Aquarium,” said general manager Catherine Pritchard.
At more than 170 kilograms, the heaviest creature to be weighed was Molokai, Birmingham’s resident green sea turtle, who also had his shell cleaned.
