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.

**Due to the COVID-19 pandemic, The Smithsonian National Museum of Natural History currently remains in a closed status for collections activities, including acquisition of collections, acceptance of donated collections, sampling, photography and other information or service requests, and incoming and outgoing loans. We appreciate your interest in resuming collections activities. The museum will send updates as they become available.**
