Squirrel monkeys, penguins and meerkats are just some of the animals that stepped on the scales on Thursday (22 August) for the start of ZSL London Zoo’s annual weigh-in.
The annual event gives keepers a chance to check the animals in their care are healthy, eating well and growing at the correct weight. Keepers say that a growing waistline can also help them to detect pregnancies, which is vital as many of the species at the zoo are endangered.
The data is then added to a database shared with zoos and conservationists across the globe. This helps keepers to compare information and provide better care for the species they are fighting to protect.
