Invertebrate Zoology

Smithsonian National Museum of Natural History

Within the Department of Invertebrate Zoology, scientists conduct original research on all 30 major invertebrate animal groups (phyla) of the world (except insects), and are stewards for the 50 million specimens of invertebrates that comprise the U.S. National Collection. The study of invertebrates offers great challenges and opportunities to contribute to the world's knowledge of these organisms.

While the Smithsonian National Museum of Natural History exhibition spaces will partially open to the public on June 18th, our collections remain closed to most staff and all researchers, and the museum’s COVID-19 loan moratorium remains in effect. Currently, there is no capacity to accommodate collections activities including visits, image requests, loans, and shipments. While there is no current date set for when on-site collections activities will resume, we will update as soon as this changes.
