description Omura's Whale Overview
Omura's whale (Balaenoptera omurai) is a relatively small species of rorqual baleen whale that was formally identified as a distinct species in 2003. It is distinguished from other Bryde's-like whales by its unique asymmetric coloration, featuring a darker right jaw and a white left jaw. This rare and elusive cetacean is found in tropical and subtropical waters, primarily across the Indo-Pacific region. Due to its relatively recent discovery, its population structure and ecology remain among the least understood of all rorquals.
