The Invertebrate Zoology collection at Bishop Museum contains over 35,000 cataloged specimen lots, thousands more uncurated lots, and is the repository for over 1000 type specimens of tropical Pacific marine invertebrates!

The IZ collection includes noteworthy material from the mesophotic zone, emerging volcanoes, submerged ancient coral reefs, and the largest marine monument in the world (Papahānaumokuākea Marine National Monument).

This is the most extensive collection of marine invertebrates in the Pacific region, and the only collections in the world devoted solely to marine invertebrates of the tropical Pacific, with the primary focus on the Hawaiian Archipelago.  The Invertebrate Zoology collection is an invaluable resource for understanding Pacific biogeography, evolution, and endemism in the Hawaiian Islands.
