🐬Hector's dolphin

Cephalorhynchus hectori (P.-J.van Bénéden, 1881)

赫氏矮海豚(學名:Cephalorhynchus hectori) ,又名贺氏矮海豚,是侏海豚属下的一種海豚,其下兩個亞種全都生活在新西蘭。其中生活在南島附近的C. h. hectori數量最多,而瀕危的毛伊海豚(C. h. maui)則生活在北島附近海域。据2010/2011年數據顯示,後一亞種僅存55只成年個體。其种加詞來自威灵頓殖民博物館(今新西兰蒂帕帕国立博物馆)館長詹姆斯·赫科特(James Hector,1834–1907),他最早對這种海豚進行了研究,但正式的科學研究則始于比利時動物學家皮埃尔·约瑟夫·贝内登。
