Bishop Museum’s Ichthyology Department, with a focus on the tropical Indo-Pacific region, houses over 40,000 cataloged lots of coral-reef fishes. This collection, primarily preserved in isopropyl alcohol, includes a wide range of specimens from single to over 100 per lot, totaling approximately 100,000 specimens. Notably, the collection features the Holotype of the Megamouth Shark (Megachasma pelagios) among its large specimens. Research in this department has significantly contributed to the taxonomy, systematics, and biogeography of coral-reef fishes, largely due to the work of Dr. John E. “Jack” Randall, who documented over 815 new species. Today, the collection continues to expand, including efforts to document larval fishes, under the guidance of Ichthyology Collections Manager, Calder Atta, building on a legacy of exploration and discovery in marine biology.
