Whipsnade Zoo: Its time for the annual weigh-inPublished20 August 2019Image source, Whipsnade ZooImage caption, These northern Rockhopper penguins had to be convinced to step onto the scales with some tasty seafood. We think they might be slightly heavier after that!Image source, Whipsnade ZooImage caption, Box turtles can live between 50 and 100 years, so might have a lot of annual weigh-ins. This little box turtle seems quite content with being weighed today - It might be because it has a slow metabolism! *Ba Dum Tsss*Image source, Whipsnade ZooImage caption, Ring-tailed lemurs Quaker and Delilah seem to do everything together - even get weighed together! We guess the Zookeeper had to separate them somehow to get a more accurate reading!Image source, Whipsnade ZooImage caption, This brown bear, called Cinderella, checks out her height. She actually ended up breaking the giant ruler after this! At two metres high, it's fair to say no one is going to mess with her.Image source, Whipsnade ZooImage caption, Tizer the Poitou donkey needs his own larger scale to step on to. These donkeys can reach up to five feet tall. But the same can't be said for Trevor the miniature donkey; he's patiently watching his turn!Image source, Whipsnade ZooImage caption, We think Behan the greater one-horned rhino has the biggest scale of them all. These rhino's weigh an average 2,100 kilograms: that's about 330 stone! We hope the scales didn't break.More on this storyPrimates at Berlin Zoo learning to use tools to find food.
