NHMO Fish collection

The NHMO Fish Collection of the Natural History Museum contains around 10,000 objects, including 27 holotypes, 11 paratypes and 82 other types. The collection was largely built through expeditions in the first half of the 20th century, of which many targeted the Arctic region (see Johannessen et al. 2023). In addition to these early expeditions, objects were obtained around the globe, including Madagascar, South America, and Antarctica. The collection also includes specimens returned from French Polynesia and Easter Island by Thor Heyerdahl (see Delrieu-Trottin et al. 2025). Most specimens were fixated in formalin upon collection.
