All creatures great and small

Mighty silverback gorillas, rare baby crocodiles and minuscule snails are just some of the animals who were weighed and measured by ZSL London Zoo’s keepers at the annual weigh-in 2014.

As well as being a key indicator of an animal’s overall well being, regular weight checks and waist measurements can also help keepers to detect pregnancies of endangered species that are part of the Zoos’ international conservation breeding programmes.

Keepers at the world’s oldest scientific zoo spend hours each year dutifully noting down the vital stats of the creatures in their care, but they do have to get creative when it comes to encouraging the animals to be measured up - from tempting tortoises to stand on a scale to persuading flighty birds to stand still on a customised perch.

Each and every measurement is then recorded into the Zoological Information Management System (ZIMS), a database shared with zoos all around the world, helping zookeepers to compare important information on thousands of endangered species.
