Species Distribution: Dwarf Sperm Whale - Hawaii

Published by Pacific Islands Ocean Observing System (PacIOOS) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-07-13T00:00:00.000+00:00
This dataset contains a collection of known point locations of dwarf sperm whales identified through direct human observation via shipborne surveys. This can be useful for assessing species abundance, population structure, habitat use, and behavior. This collection is aggregated from multiple survey periods. Each data point contains attributes for further information about the time and source of the observation. This dataset was compiled by the Pacific Islands Ocean Observing System (PacIOOS) and may be updated in the future if additional data sources are acquired. Cascadia Research Collective (CRC) has been undertaking shipborne surveys for odontocetes in Hawaiian waters since 2000. Photo-identification indicates a small resident population of dwarf sperm whales off of Hawaii Island as well as an offshore population. Less is known about this species around the other Hawaiian islands. For further information, please see: http://www.cascadiaresearch.org/hawaiian-cetacean-studies/dwarf-and-pygmy-sperm-whales-hawaii
