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.

As of April 01, 2022 the Smithsonian Museum of Natural History has lifted its COVID-19 restrictions. While the exhibition spaces and collections will be open, we are currently working through a backlog of requests from the past 2 years. Access to the Invertebrate Zoology collections, through loans or in-person visits, is only available on a case by case basis. Please note that due to limited staff availability and a high volume of requests, we may not be able to accommodate your request or it may be postponed to a later date. Our Collections Management team will review and work with you directly about specific details and expected timeline. We appreciate your patience and flexibility as we navigate this transitionary period.

The Year of the Crayfish

2022 has been quite the busy year for the crayfish in our collection! With our lab at the Museum Support Center starting to bustle with activity once again, we've taken a moment to look at the exciting work some of our recent visitors have been up to
