Size differences
The complex includes larger and smaller forms: the common B. brydei is larger, while B. edeni and some coastal/Indo‑Pacific forms are smaller.
Bryde’s Whale
A rorqual complex of warm-temperate and tropical whales, Bryde's whale refers to several closely related forms including Balaenoptera brydei and B. edeni.

Bryde's whale (pronounced BRUU-dəz) refers to a complex of closely related rorquals rather than a single, well‑defined species. The complex putatively comprises three species and possibly four; taxonomy and classification remain unclear due to limited definitive information and research. The common Bryde's whale (Balaenoptera brydei) is described as a larger form with a worldwide distribution in warm temperate and tropical waters. The Sittang or Eden's whale (Balaenoptera edeni) is a smaller form that may be restricted to the Indo‑Pacific. Additional forms include a smaller coastal form off southern Africa and a tentatively recognized Indo‑Pacific form differing in skull morphology. Omura's whale (B. omurai) was formerly considered a pygmy Bryde's whale but is now recognized as a distinct species. Rice's whale (B. ricei), once considered a population of Bryde's whale, was described as a separate species in 2021.
The strongest linked planning options currently surface around destinations such as Mahé and countries such as Seychelles for divers building trips around bryde’s whales.
