Occurrence of Omura’s whale, Balaenoptera omurai (Cetacea: Balaenopteridae), in the Equatorial Atlantic Ocean based on Passive Acoustic Monitoring
The current known distribution of Omura’s whale includes the tropical and warm temperate waters of the westernPacific, Indian, and Atlantic Oceans. Evidence of their presence in the Atlantic Ocean is based on beach castspecimens found on the coasts of Mauritania (North Atlantic) and Northeastern Bra...
