If any animals at London Zoo have been sneakily stealing extra portions of food from their friends they’re about to be found out, because the annual weigh-in is taking place.
This means that every one of the 16,000 or so animals, across 750 species, including penguins, meerkats, lions and owls, are put on the scales and measured.
The measurements are then recorded into the Zoological Information Management System (ZIMS) where they can be shared with zoos across the world, which zoologists use to compare information on thousands of endangered species.

ZSL’s Zoological Director, David Field, said: “We need to know the vital statistics of every animal at the Zoo – however big or small.
“This information helps us to monitor their health, their diets and their general well-being. By sharing it with other zoos and conservationists, we can use this knowledge to protect wild animals, and use it to assess their health, their behaviours and even their ages”.
