The Invertebrate Zoology Collection at Bishop Museum contains over 35,000 cataloged lots with over 1,000 type specimens. It is the only collection in the world devoted solely to marine invertebrates of the Pacific islands, with its primary focus being the Hawaiian Archipelago. It primarily houses marine animals that span multiple animal groups, including Porifera (sponges), Cnidaria (corals, jellies), Crustacea (crabs, lobsters), and Echinodermata (sea stars, urchins). The collection represents more than 100 years of scientific activity in Hawaiʻi and the Pacific.
