ZSL’s Zoological Director, David Field says: “We need to know the vital statistics of every animal at the Zoo – however big or small.”

Zookeepers at the London Zoo are responsible for more than 16,000 animals, spending countless hours recording the weight and measurements of each and every animal, including penguins, meerkats, lions and owls.  The measurements are collated in the Zoological Information Management System, from which zoologists can use the data to compare information on thousands of endangered species.
