Zookeepers make notes of every invertebrate, bird, fish, mammal, reptile, and amphibian. The compulsory count is required as part of ZSL London Zoo's license. There were 50 extra reptiles at London Zoo on Thursday. It was the start of the zoo's annual stock-taking, when keepers undertake a week-long census, and the press had been invited in for the count of the more photogenic animals.
