Brownell Jr.3 1 Anderson Cabot Center for Ocean Life, New England Aquarium, Boston, MA, United States, 2 National Museum of Nature and Science, Tokyo, Japan, 3 Southwest Fisheries Science Center, NOAA Fisheries, Monterey, CA, United States When the Omura’s whale (Balaenoptera omurai) was first described in 2003, it was known from only three locations: the southern Sea of Japan, and the vicinities of the Cocos (Keeling) Islands and Solomon Islands. Work over the following decade suggested a range limited to the eastern Indo-Pacific, but more recent discoveries in the western Indian Ocean and Atlantic Ocean suggested a more widespread range than previously thought. Here we use all available sources of information, including published papers, unpublished reports, and internet-based accounts, substantiated through genetic, morphological, photographic and acoustic documentation, to compile accounts of Omura’s whales globally. Reports increased precipitously since 2015 after Edited by: publication of the first detailed external description of the species, reflecting the impact Rob Harcourt, of the recently elevated awareness of the species. We report 161 accounts from 95 Macquarie University, Australia locales in the waters of 21 range states, and found that the species is widely distributed Reviewed by: Asha de Vos, in primarily tropical and warm-temperate locations. Currently it is known from all ocean The Sri Lankan Blue Whale Project basins with the exception of the central and eastern Pacific.
