Alan Resetar, Collection Manager of the Division of Amphibians and Reptiles at the Field Museum of Natural History, Chicago, taking tissue specimens from a cryogenic storage facility that is cooled with liquid nitrogen.



As biologists describe new species and add to our understanding of the interrelated nature of life on Earth, a species becomes extinct every 20 minutes (100 to 1000 times the background extinction rate as seen in the fossil record). Collections in natural history museums play important roles in conservation, education and research. Most of that work and the associated specimens are not on public display in museumsâ typically, less than five percent of specimens are exhibited.
