About this species
Bryde's whale ( BRUU-dəz), or the Bryde's whale complex, putatively comprises three species of rorqual and possibly four. The "complex" means the number and classification remain unclear because of a lack of definitive information and research. The common Bryde's whale (Balaenoptera brydei, Olsen, 1913) is a larger form that occurs worldwide in warm temperate and tropical waters, and the Sittang or Eden's whale (Balaenoptera edeni, Anderson, 1879) is a smaller form that may be restricted to the Indo-Pacific. Also, a smaller, coastal form of B. brydei is found off southern Africa, and perhaps another form in the Indo-Pacific 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 thought to be a pygmy form of Bryde's, but is now recognized as a distinct species. Rice's whale (B. ricei), which makes its home solely in the Gulf of Mexico, was once considered a distinct population of Bryde's whale, but in 2021 it was described as a separate species.

艾氏鲸(学名:Balaenoptera edeni)又名鳀鲸,为须鲸科须鲸属的动物。在中国大陆,分布于东海、南海等海域,在福建、广东及海南沿海相对常见,一般栖息温暖的近海。该物种的模式产地在缅甸。艾氏鲸在形态上与布氏鲸极为相似,但艾氏鲸的吻部一般更加尖锐,头部整体呈V形,且具有五条脊突(布氏鲸有三条)。相比其他大型须鲸,艾氏鲸是更积极的捕食者,其主要食物为各类小型鱼类。
常见的布氏鲸(Balaenoptera brydei, Olsen, 1913)体型较大,分布于全球温暖的温带和热带水域;而艾氏鲸(Balaenoptera edeni, Anderson, 1879)体型较小,可能仅限于印度洋-太平洋海域。此外,在非洲南部沿海也发现了一种体型较小的布氏鲸近岸型,而印度洋-太平洋海域可能还存在另一种布氏鲸,其头骨形态有所不同,暂且称之为印度洋-太平洋布氏鲸。大村鲸(B. omurai, Wada et al. 2003)曾被认为是布氏鲸的侏儒型,但是现在已被确认为一个独立的物种。赖氏鲸(B. ricei)仅生活在墨西哥湾,曾被认为是布氏鲸的独立族群,在2021年被描述为独立物种。
