bryde's whale
Bryde's whale or Bryde's whale complex () putatively comprises two species of rorqual and maybe three. The "complex" means the number and classification remains unclear because of a lack of definitive information and research. The common Bryde's whale (''Balaenoptera brydei'', Olsen, 1913), a larger form that occurs worldwide in warm temperate and tropical waters, and the sittang or Eden's whale (''B. edeni'', Anderson, 1878), a smaller form that may be restricted to the Indo-Pacific.〔(【引用サイトリンク】title=Bryde's Whales, Balaenoptera edeni )〕 There is also a smaller, coastal form of ''B. brydei'' off southern Africa, and perhaps another form in the Indo-Pacific which differs in skull morphology, tentatively referred to as the Indo-Pacific Bryde's whale. The recently described Omura's whale (''B. omurai'', Wada et al. 2003), was formerly considered a "pygmy" form of Bryde's, but is now recognized as a distinct species.
''B. brydei'' gets its specific and common name from Johan Bryde, Norwegian consul to South Africa who helped establish the first modern whaling station in the country, while ''B. edeni'' gets its specific and common name from Sir Ashley Eden, former High Commissioner of Burma (Myanmar). Sittang whale refers to the type locality of the species.
==Etymology==
In Japan, early whalers called it or . It preys on the anchovy and it was commonly associated with the skipjack. As modern whaling shifted to the Sanriku area, whalemen confused it for the sei whale; now only applies to the latter. Incidentally, anchovies are dominant prey for both species off Japan. They are now called , for their resemblance to the sei whale.〔Omura, Hidero. (1977). Review of the Occurrence of the Bryde's Whale in the Northwest Pacific. ''Rep. Int. Commn.'' (Special Issue 1):88-91.〕
