London Zookeeper Laura Childs poses for a picture with a spiney stick insect as she takes part in a photocall to promote London Zoo's annual stock take of animals on January 5, 2010. At London Zoo, the animals come two by two โ€” and sometimes in fours and sixes as well. The zoo's annual 'stocktaking' took place on Tuesday, giving keepers a chance to check on the numbers of everything from stick insects to tigers โ€” and even a sex-change meerkat.
