A “jungle nymph” is measured during the annual weight-in ZSL London Zoo on August 21, 2014 in London, England.

This is combined with animal measurement data collected from over 800 zoos and aquariums in almost 80 countries, from which zoologists can compare information on thousands of endangered species.
