It was a busy old time at London Zoo this week, reports the Daily Mail, where over 19,000 animals were having their annual weight and height checked . Some creatures, such as rhinos, tigers and okapis, had to be coaxed on to specially constructed larger scales. The statistics are shared with other zoos across the world to allow keepers to compare information about endangered species. Zoological manager Mark Habben said: “We have to know the vital statistics of every animal at the zoo, however big or small.”
