California Academy of Sciences

Established in 1914, Invertebrate Zoology is one of the oldest departments in the Academy, representing more than 160 years of scientific research. In combining with the Department of Geology in 1982, it became home not only to the most diverse collections in the Academy—encompassing an enormous range specimens and strengths—but to a robust staff of curators, researchers, collection managers, students, and more. Through field and lab work, multi-disciplinary expeditions, and scientific publications, our scientists rigorously advance knowledge in their areas of expertise. From octocorals and opisthobranch mollusks to echinoderms and paleontology, our work—and the collections we maintain—is a vital piece of the Academy's overall efforts to explore, explain, and sustain life on Earth.

Chicago Academy of Sciences

The Chicago Academy of Sciences’ malacology collection consists of freshwater, marine, and terrestrial Mollusca, as well as specimens representing Echinodermata, Porifera, Brachiopoda, and Cnidaria. It is the third largest in the state of Illinois with approximately 15,000 specimens, split mainly between gastropods and bivalves. Many specimens are associated with Academy collectors, e.g. William Stimpson (1832-1872) or Frank C. Baker (1867-1942). Other major collectors include Elizabeth Emerson Atwater, William Wirt Calkins, Ruthven Deane, J. H. Handwerk, R. L. Lea, Howard N. Lyon, E. N. King, J. W. Velie, Frank Morley Woodruff, and Mrs. E. C. Wiswall. The collection consists mainly of North American varieties of mollusk, with a strong regional focus on the Midwest. Approximately 24% of domestic lots originated in Illinois. Academy expeditions in the late 1800s and early 1900s contributed a significant number of specimens from California and Florida, while a number of specimens collected by William Stimpson came from the eastern coast of the United States. Additional specimens originated in Bermuda, the Bahamas, Mexico, China, Indonesia, and Japan. Collection includes 7 holotypes and 50 syntypes, and specimens were primarily collected pre-1945.

Delaware Museum of Natural History – Mollusks

The Museum's mollusk collection consists of more than 2 million specimens, making it one of the largest in the United States. The 220,000 cataloged lots represent more than 18,000 species. Worldwide in scope and covering all seven living classes of mollusks, our holdings include marine gastropods (45%), land and freshwater gastropods (30%), marine bivalves (15%), freshwater bivalves (5%) and other (5%). The Museum's mollusk collection is primarily dry shells, with some alcohol preserved cephalopod specimens. Most specimens are recent; however there is some Cenozoic fossil material. Our type collection contains more than 1,200 lots.

FMNH-Invertebrate Zoology

Field Museum of Natural History Invertebrates

Established in 1938, the Division of Invertebrates is in charge of all invertebrate groups except insects and other non-marine arthropods. The first curator of this Division was Fritz Haas, formerly of the Senckenberg Museum in Frankfurt, Germany. Haas (1938 - 1969) and his successor Alan Solem (1957 - 1990) built massive mollusk collections, particularly strong in unionid bivalves and terrestrial snails, reflecting their respective research interests. Current curators Rüdiger Bieler (1990 -) and Janet Voight (1990 -) focus their research and collection-building on marine molluscan groups. The varied curatorial research interests, the collecting efforts of past and present collections managers (e.g., John Slapcinsky and Jochen Gerber), and acquisitions of private collections and "orphan collections"

Florida Museum of Natural History

The UF Invertebrate collection holds ~510,000 databased lots of mollusks and marine invertebrates. It began as a Malacology collection almost 100 years ago and ~85% of the holdings are still mollusks. Since 2000 the collection was expanded to cover all invertebrate phyla, focusing on marine taxa. Today it holds >40,000 species from 28 phyla.

Frost Entomological Museum

The Frost Entomological Museum is an active research institution, associated with the Pennsylvania State University's flagship campus in University Park. The museum houses a research collection, estimated at 2 million arthropod specimens, and a public exhibition and educational space. Although the museum was founded in 1969 much of the collection dates to the early 1900s and even the late 1800s. The research collection provides a record of the insect biodiversity of the Commonwealth of Pennsylvania and the eastern and southeastern United States. Major collection holdings include: Aphididae, Anoplura, and Odonata.

University of Alaska Museum

A set of collections presently consisting of over 8,000 lots of marine invertebrates has been housed at the Museum since the 1970s. James Morrow, Ron Smith, and several other University of Alaska researchers established and built the nucleus of the collection. Most of the data associated with both collections are in the Arctos database, however a significant number of records for marine invertebrates housed in the museum’s collections remain to be incorporated into this electronic resource. These collections were under the care of Nora Foster until 1998 and of Dr. Gordon Haas until 2006. Andrés López joined the Museum of the North as curator of fishes in the Fall of 2008. Thanks to collaborative relationships with State and Federal agencies, the Aquatic collections are continuously growing and providing an improved representation of Alaska’s aquatic faunas.

UMMZ-Mollusk Collection

University of Michigan Museum of Zoology

The Mollusk Division incorporates approximately 5 million specimens and has long ranked amongst the most important freshwater and land snail collections in North America. Approximately 251,000 cataloged lots including over 406 holotype specimens and more than 1638 paratype lots are preserved as dry shells, ethanol preserved specimens, frozen tissues, lyophilized tissues, fossil material and radular microscope slide mounts. Mollusks from all regions of the planet are represented, with most being from North America, particularly from southeastern and upper mid‐western USA drainages. With the exception of Monoplacophora and Aplacophora, all extant molluscan classes are represented. The collection includes a number of significant subcollections; Bryant Walker Collection (one of the world’s largest private mollusk collections containing over 100,000 lots and about two million specimens), Royal Ontario Museum Collection [outstanding collection of North American (principally Canadian) freshwater and land mollusks], F. C. Baker Wisconsin Freshwater Mollusk Collection (one of the most extensive North American freshwater mollusk collections), Stelfox Sphaeriid Collection (one of the most important reference collections of cosmopolitan freshwater bivalve family Sphaeriidae), and Lyophilized Tahitian Land Snails (about 1600 freeze‐dried tissue samples of a now largely extinct snail family).
