Marine Biodiversity Center

Most species on Earth are animals, and most animals are invertebrates, so most of the Earth’s astonishing biodiversity is in the invertebrate animals. The Marine Biodiversity Center is the museum’s core facility for the curation of these remarkable animals. Collections come to the museum from a variety of research projects and government agencies.
