The University of Michigan Museum of Zoology is now the world’s largest holder of snake specimens. This follows a donation from Oregon State University of tens of thousands of reptile and amphibian specimens, mostly snakes, to Michigan’s Research Museums Center. The collection represents the lifelong work of retired herpetologists Lynne Houck and Stevan Arnold. With this addition, the University of Michigan surpasses the Smithsonian Institution and the American Museum of Natural History in herpetological specimens. Many of these specimens date back to before the Civil War, adding historical value. Amphibians and reptiles are key indicators of environmental health and ecosystem stability.

The collection contains about 30,000 snake specimens and 30,000 frozen tissue samples, which will support genetic and evolutionary research. Associate Professor Hernán López-Fernández said the specimens will assist molecular genetics studies and may benefit medicine in the future. Preserved in 75% ethanol, these specimens allow rare studies of adult snakes and their offspring. Cataloging this large collection is detailed work, but staff are enthusiastic about new research opportunities. The acquisition is expected to lead to studies on trait evolution between mother snakes and their young.
