For the next five days, zookeepers will catalogue every meerkat, sort every spider, and take ant population approximations to confirm the presence of every animal living under its care. Sure, this is a publicity stunt. But it's an awesome publicity stunt that actually does find out which creatures have gone missing, passed away, or been born in the last year.
And even more importantly, it's darn cute. You can see the census in action for yourself until Thursday, or just click through our adorable slideshow of the counting in progress. Oh, and if you notice any missing penguins, please inform us immediately. (Guardian UK)
