It's a new year, and across the globe, zoos are taking stock of their vibrantly diverse menageries. Animals are counted, measured, and weighed in an effort to keep tabs on the huge critter populations housed within the zoos' walls. At the London Zoo, keepers had the daunting task of rounding up more than 18,000 animals representing 750 different species. But it's all for a great cause: once the tally is complete, zoos share the information to help breeding programs aimed at boosting endangered species populations.
