Welcome to the Antarctic Invertebrates Website! With nearly 19 million specimens, the United States Antarctic Program (USAP) collection at the National Museum of Natural History (NMNH) is the most valuable tool we have for the study of Antarctic and Subantarctic marine invertebrates. The collection includes type and non-type material dating back to the U.S. Exploring Expedition of 1838-1842. On this website you will find specimens from the Southern Ocean and nearby waters, as far North as 30° S.
From the toolbar above you may pursue images, literature references, maps or other data concerning any Antarctic invertebrate animal represented in the NMNH collections. See History and Current Activities to read about early Antarctic research expeditions as well as our latest visiting scientists and their work with the collection. Any species or higher taxon in our collections may be looked up through Biodiversity, the various ice-breaking research vessels or expeditions through Station Data, or the vast literature on the Antarctic under Bibliography. We hope you will find this website useful for tracing specimens, expeditions and publications.
