London Zoo Census Brings Out Creatures Big and Small
The London Zoo holds its annual stocktaking at the the start of each year.
Young visitors look at penguins through a glass port hole at the London Zoo in London, Britain, on Jan. 4, 2016. The zoo's annual stocktake requires keepers to check on the numbers of every one of the 800 different animal species, including every invertebrate, bird, fish, mammal, reptile, and amphibian.
A ring-tailed lemur looks up during the annual stocktake. The annual audit takes keepers a week to complete and all of the information is shared with zoos around the world via the International Species Information System, where it’s used to manage the worldwide breeding programs for endangered animals.
