The staff at the London Zoo is giving 19,000 animals their annual physical, getting their lengths and weights over the course of several days.

More than 14,000 species will participate in the zoo's annual event, with the zoo staff expected to take several days to weigh and measure every mammal, bird, reptile, fish and invertebrate in its care to ensure accurate and up-to-date information.

The results will go into a database that's shared with zoos around the world, according to a statement by the London Zoo. This helps zookeepers to compare important information on thousands of threatened species.
