Zoological research at The Field Museum is organized around six world-class collections: Amphibians and Reptiles, Birds, Fishes, Insects (with arachnids and myriapods), Invertebrates, and Mammals. Each collection has its own staff, maintaining holdings that together total more than 19.5 million zoological specimens from around the world. In addition to their diverse research programs, our Curators and staff actively build collections, train graduate, undergraduate, and high school students, contribute to exhibits and other public programs, serving the diverse needs of the public and scientific communities.
